The provided FDA 510(k) clearance letter and associated S510(k) summary documents describe a class II medical device, Geistlich Bio-Gide and its variants, which are resorbable bilayer membranes and bone grafting materials. This submission is for a determination of substantially equivalent to a predicate device.
Crucially, this document is focused on demonstrating substantial equivalence based on material characteristics, manufacturing processes, and performance data for the device itself (a physical membrane and bone grafting material), not on the performance of an AI/ML powered device.
Therefore, most of the requested information regarding acceptance criteria, training/test sets, expert adjudication, MRMC studies, standalone performance, and effect sizes for AI assistance are not applicable to this type of medical device submission. The "study that proves the device meets the acceptance criteria" in this context refers to the non-clinical performance testing conducted to confirm the physical and biochemical properties of the new device are equivalent to the predicate device, especially after changes to supplier and manufacturing processes.
Here's an attempt to extract relevant information and note the inapplicable sections based on your request:
Acceptance Criteria and Device Performance (for a physical medical device)
1. A table of acceptance criteria and the reported device performance
Since this is not an AI/ML device, the acceptance criteria are not typically expressed in terms of accuracy, sensitivity, or specificity. Instead, they are based on physical, chemical, and biological properties demonstrating equivalence to a predicate device. The performance data provided is primarily comparative to the predicate.
Acceptance Criterion (Implied) | Reported Device Performance (Summary from Document) |

The "analysis" column in the provided tables consistently states "The material of construction is identical," "The sizes offered are identical/similar," etc., implying the acceptance criterion is indeed identity or substantial similarity to the predicate.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample Size for Test Set: Not explicitly stated as a single "test set" in the context of an AI/ML model. The performance data consists of various physical, biochemical, and experimental tests. The number of samples for each specific test (e.g., number of membranes for tensile strength testing) is not provided.
- Data Provenance: Not specified regarding country of origin. The studies are described as "in vitro and in vivo biocompatibility," "sterilization," "shelf-life," "bench," and "clinical performance studies" leveraged from previous predicate device submissions (e.g., K212463, K171643). These are likely a mix of lab-based and potentially historical clinical data. It is not specified if these are prospective or retrospective studies; however, given they are leveraged from previous clearances, they would be historical for this specific submission.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Not Applicable. This is not an AI/ML diagnostic device requiring expert interpretation or ground truth establishment in that manner. The "ground truth" for a resorbable membrane involves objective physical, chemical, and biological measurements, and comparison to established standards and predicate device characteristics, not expert consensus on image interpretation.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not Applicable. No human adjudication method is described or relevant for the physical and chemical performance tests conducted on this medical device.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- Not Applicable. This is not an AI-assisted device, so MRMC studies are not relevant.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not Applicable. This is not an AI algorithm. Its "standalone" performance refers to its intrinsic physical and chemical properties.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- Not Applicable / Different Context. The "ground truth" for this device's performance is established by:
- Objective Measurements: Results of standardized physical and biochemical tests (e.g., SEM, porosity, tensile strength, DSC, solubility, degradation, molecular weight, hydration capacity, suture pull-out force).
- Regulatory Standards: Compliance with ISO and ASTM standards (e.g., ISO 10993-1, ISO 11137 series, ISO 22442-3, ASTM F2450-18, ASTM F2150-19, ASTM F2212-20).
- Predicate Device Data: Comparison and leveraging of performance data (biocompatibility, sterilization, shelf-life, bench, clinical) from previously cleared predicate devices. The claim is substantial equivalence, meaning it performs as safely and effectively as the legally marketed predicate.
8. The sample size for the training set
- Not Applicable. This is a physical medical device, not an AI/ML model, so there is no "training set."
9. How the ground truth for the training set was established
- Not Applicable. As there is no training set for an AI/ML model, this question does not apply.
Summary of the Study Proving Device Meets Acceptance Criteria (in this context):
The "study" conducted for the Geistlich Bio-Gide product family in this 510(k) submission primarily consists of a comprehensive battery of non-clinical performance tests combined with the leveraging of existing performance data from previously cleared predicate devices. The purpose of these tests was to demonstrate that modifications (e.g., new slaughterhouse, non-significant manufacturing changes) did not alter the fundamental safety and effectiveness of the device, making it substantially equivalent to its predicates.
The non-clinical tests included:
- Physical and Biochemical Testing: SEM (surface morphology), porosity, tensile strength, DSC (onset temperature), suture pull-out force, solubility, enzymatic degradation, SDS-PAGE (molecular weight distribution), and hydration capacity. For Geistlich Bio-Gide Forte and Compressed, handling properties were also evaluated.
- Other Experimental Testing: Viral safety according to ISO 22442-3:2007.
These tests, performed on the modified devices, aimed to show that their properties were consistent with a product that would continue to perform as intended and as safely and effectively as the predicate devices. The acceptance criteria were implicitly that the new devices exhibit equivalent performance characteristics to the cleared predicate devices, as supported by these various in vitro and experimental studies and referencing past clinical data from the predicates.

This document is a 510(k) clearance letter for a bone grafting material, Geistlich Bio-Oss® and Geistlich Bio-Oss Pen®. The core claim of the submission (K251786) is that the new devices are "substantially equivalent" to previously cleared predicate devices.
The request asks for information typically found in an FDA submission for AI/ML-enabled devices, particularly those involving diagnostic aids. This 510(k) submission, however, is for a physical medical device (bone grafting material) and does not involve AI or algorithms for diagnostics or image analysis. Therefore, many of the requested elements are not applicable to this type of traditional medical device clearance.
Here's a breakdown of the requested information based on the provided document, highlighting what is not applicable:
Acceptance Criteria and Device Performance for Geistlich Bio-Oss® and Geistlich Bio-Oss Pen® (K251786)
It is crucial to understand that this 510(k) is for a physical bone grafting material, not an AI/ML-enabled diagnostic device. Therefore, the "acceptance criteria" and "study that proves the device meets the acceptance criteria" are focused on demonstrating substantial equivalence to predicate devices through material properties, manufacturing consistency, biocompatibility, sterilization, and basic handling characteristics, rather than diagnostic performance metrics (e.g., sensitivity, specificity, AUC) and reader studies typically associated with AI.
The primary "acceptance criterion" for this 510(k) is demonstrating substantial equivalence to the predicate devices, particularly concerning the addition of an alternate raw material supplier and minor manufacturing/release testing changes, without raising new questions of safety or effectiveness.
1. A table of acceptance criteria and the reported device performance
For a physical bone grafting material, the "acceptance criteria" relate to material composition, physical properties, biocompatibility, sterility, and manufacturing consistency. The provided document details the comparison of characteristics to the predicate and references studies demonstrating these aspects.
Acceptance Criteria Category (Implied by Submission) | Reported Device Performance (as described in 510(k)) |
---|---|
Material Composition | Identical to predicate: purified spongiosa (cancellous) bovine bone mineral granules. (New: alternate raw material supplier for bovine material, deemed not to raise new safety/effectiveness questions.) |
Form | Identical to predicate: Granules or block form. Geistlich Bio-Oss Pen® is granules pre-filled in a syringe-like applicator. |
Particle Size | Identical to predicate: 0.25 – 1.0 mm, 1.0 – 2.0 mm. |
Block Size | Identical to predicate: ~1 x 1 x 2 cm. |
Single-Use | Identical to predicate: Yes. |
Sterilization Method | Identical to predicate: Gamma, X-ray (Geistlich Bio-Oss® only). |
Manufacturing Methods | Non-significant changes to manufacturing facilities and equipment. Deemed not to raise different questions of safety/effectiveness. |
Release Testing Methods | Non-significant changes to release testing methods. Deemed not to raise different questions of safety/effectiveness. |
Biocompatibility | Leverage results from predicate/reference devices (K120601, K240661). Conforms to ISO 10993-1:2018. |
Sterilization & Shelf-Life | Leverage results from predicate/reference devices (K120601, K240661). Conforms to ISO 11137-1/2/3 and ISO 11607-1/2. |
Viral Inactivation | Leverage results from reference devices (K242510, K240661). Conforms to ISO 22442-1/2/3. |
Handling and Performance (Bio-Oss Pen) | Qualitative and quantitative handling and performance studies (and usability study) undertaken to support design modifications to the syringe. (Details are not in the provided text, but mentioned as having been done.) |
Clinical Performance (General) | Leverage results from predicate/reference devices (K120601, K240661, K122894, K970321) for bench and non-clinical/clinical performance. No new clinical trials were explicitly required or presented in this summary for the "substantial equivalence" claim. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Not Applicable in the typical AI/ML context. For a physical device like a bone graft, "test set" would typically refer to batches subjected to quality control, biocompatibility testing, or perhaps animal studies for efficacy. The document references leveraging prior studies for performance data.
- Data Provenance: The document does not specify the country of origin for the leveraged study data or whether it was retrospective or prospective, as this level of detail is not required for a 510(k) summary focused on substantial equivalence of a material.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Not Applicable. This pertains to establishing ground truth for diagnostic image interpretation, which is not relevant for a bone grafting material. Ground truth for a bone graft is established through material characterization, biocompatibility testing (e.g., cytotoxicity, sensitization, implantation tests analyzed by pathologists), and gross/histological evaluation in animal models. These "experts" would be materials scientists, toxicologists, and veterinary pathologists, but their number and specific qualifications are not detailed in this 510(k) summary because new studies of this nature were not performed for this submission; prior data was leveraged.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not Applicable. This refers to consensus methods for establishing ground truth in diagnostic studies (e.g., by radiologists). This is irrelevant for a bone grafting material.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- Not Applicable. This is specific to AI-enabled diagnostic devices assessing human reader performance. This device is a physical bone graft.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not Applicable. This is specific to the performance of an AI algorithm in isolation. This device does not have an AI algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- For this type of device, "ground truth" for performance relates to:
- Material Characterization: Physical and chemical properties confirmed through lab assays (e.g., composition, particle size, porosity).
- Biocompatibility: Established through standardized in vitro and in vivo tests (e.g., cytotoxicity, irritation, sensitization, genotoxicity, implantation tests), with histological and pathological evaluations of tissues for reaction.
- Sterility: Confirmed through microbiological testing.
- Viral Safety: Demonstrated through validated viral inactivation processes.
- Bench and Non-clinical/Clinical Performance: Based on previous studies (potentially animal models or human clinical data from the predicate) demonstrating the material's ability to integrate with bone, support bone formation, etc. The document generally mentions "bench and non-clinical/clinical performance" data leveraged from predicates.
8. The sample size for the training set
- Not Applicable. This refers to AI model training data. This device does not use an AI model.
9. How the ground truth for the training set was established
- Not Applicable. This refers to how data used to train an AI model was labeled or validated. This device does not use an AI model.
In summary, the provided FDA 510(k) letter is for a traditional physical medical device. The concepts of "acceptance criteria" and "study proving device meets acceptance criteria" for such devices revolve around demonstrating that the new device (or changes to an existing one) meets established safety and performance benchmarks relevant to its physical and biological function, primarily by showing substantial equivalence to existing, cleared devices. This is a fundamentally different assessment from that of an AI/ML diagnostic tool, which would necessitate the detailed information requested in the prompt.

SwissGraft X is intended for the following uses:
- augmentation or reconstructive treatment of the alveolar ridge
- filling of infrabony periodontal defects
- filling of defects after root resection, apicoectomy, and cystectomy
- filling of extraction sockets to enhance preservation of the alveolar ridge
- elevation of the maxillary sinus floor
- filling of periodontal defects in conjunction with products intended for Guided Tissue Regeneration (GTR) and Guided Bone Regeneration (GBR)
- filling of peri-implant defects in conjunction with products intended for Guided Bone Regeneration (GBR).
SwissGraft X is a biocompatible bone mineral matrix and is manufactured from purified spongiosa (cancellous) bovine bone mineral granules. SwissGraft X serves as a matrix consisting of interconnected macro- and micropores. The material is highly porous, hydrophilic, and has a large inner surface area. SwissGraft X is sterilized by x-ray irradiation. SwissGraft X is provided in granule form.
The provided document is an FDA 510(k) clearance letter for a bone grafting material called "SwissGraft X." It does not describe an AI medical device or present a study comparing the device's performance against acceptance criteria in the manner typically expected for AI/software-as-a-medical-device (SaMD) clearances.
Instead, this document describes a traditional medical device (bone grafting material) seeking clearance based on substantial equivalence to a predicate device. The performance data section refers to standard biocompatibility, sterilization, shelf-life, and packaging validation, along with characterization of structural, mechanical properties, and granule size distribution – all common for a physical medical product.
Therefore, many of the requested elements (e.g., acceptance criteria for diagnostic performance, sample size for test set, number of experts, adjudication method, MRMC study, standalone performance, ground truth types for training/test sets) are not applicable to the information contained in this specific FDA clearance letter for SwissGraft X.
Here's an analysis based on the available information, with notes where information is not present or not applicable to an AI device:
1. Table of Acceptance Criteria and Reported Device Performance
As "SwissGraft X" is a bone grafting material and not an AI or diagnostic device, the acceptance criteria relate to its physical and biological properties rather than diagnostic performance metrics (like sensitivity, specificity, AUC). The document refers to "testing against final product specifications" and "characterization of structural and mechanical properties" for the new product line's smaller granule sizes and different filling weights compared to the predicate device. Specific numerical acceptance criteria or performance values are not detailed in this summary, but the conclusion states that these evaluations support substantial equivalence.
Acceptance Criteria Category (Implied from Performance Data) | Reported Device Performance |
---|---|
Material Biocompatibility | Results from applicant's own predicate device (K240661) were leveraged. Implied to meet established standards. Specific results not provided in this summary. |
Sterilization Efficacy | Results from applicant's own predicate device (K240661) were leveraged. Implied to meet established standards for X-ray sterilization. Specific results not provided in this summary. |
Shelf-Life Stability | Results from applicant's own predicate device (K240661) were leveraged. Implied to demonstrate stability over its intended shelf life. Specific results not provided in this summary. |
Packaging Validation | Results from applicant's own predicate device (K240661) were leveraged. Implied to ensure package integrity and sterility. Specific results not provided in this summary. |
Final Product Specifications | "Testing against final product specifications" undertaken. Implied to meet all defined specifications for the device. Specific numerical specifications or results not provided in this summary. |
Pore, Surface, and Internal Structure Characteristics | "Characterization of structural and mechanical properties" undertaken. Implied to be comparable to the predicate device within acceptable ranges. Specific results not provided in this summary. |
Liquid Uptake | "Characterization of structural and mechanical properties" undertaken. Implied to be comparable to the predicate device within acceptable ranges. Specific results not provided in this summary. |
Granule Size Distribution | "Characterization of structural and mechanical properties" undertaken (including Granule size distribution). The device has a reduced granule size range (0.25-0.6 mm) compared to the predicate (0.25-1.0 mm, 1.0-2.0 mm), but this was the specific change being evaluated and found to be sufficiently similar for substantial equivalence. Specific results not provided in this summary, but the conclusion of substantial equivalence implies acceptable performance. |
2. Sample Size Used for the Test Set and Data Provenance
This information is not provided in the 510(k) summary as it typically would be for a clinical validation or AI performance study. The "Performance Data" section states that results from the applicant's own predicate device (K240661) were "leveraged" for biocompatibility, sterilization, shelf-life, and packaging validation. For the specific differences (granule size and filling weights), "testing against final product specifications" and "characterization of structural and mechanical properties" were undertaken. The exact sample sizes for these bench tests are not disclosed.
Data Provenance: The manufacturer is "Geistlich Pharma AG" based in Wolhusen, Switzerland. The predicate device's data was used, but details on the provenance of those original studies are not given here. The studies mentioned are primarily bench/laboratory based for material characterization, not typically clinical or retrospective/prospective data sets in the AI sense.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Those Experts
This concept is not applicable here. The device is a physical bone grafting material, not a diagnostic AI that requires expert-established ground truth for performance evaluation. Its performance is assessed through laboratory tests (e.g., material characterization, sterilization validation) against technical specifications, not against expert clinical diagnoses.
4. Adjudication Method for the Test Set
Not applicable. There is no "test set" in the context of expert adjudication for diagnostic accuracy.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No. This is a clearance for a bone grafting material, not an AI device, so MRMC studies are not relevant.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Not applicable. "SwissGraft X" is not an algorithm or software. It is a physical bone grafting material.
7. The Type of Ground Truth Used
For a physical device like SwissGraft X, "ground truth" refers to established scientific/engineering principles, material standards, and validated test methods (e.g., for biocompatibility, sterility, material properties) rather than clinical ground truth (like pathology or expert consensus). The product is evaluated against its own "final product specifications" and characterization results are compared against those of the predicate device.
8. The Sample Size for the Training Set
Not applicable. The device is a physical product, not an AI model that requires a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable. The device is a physical product, not an AI model that requires a ground truth for a training set.

SwissMembrane X is intended for the following uses:
- augmentation around implants placed in immediate extraction sockets;
- augmentation around implants placed in delayed extraction sockets;
- localized ridge augmentation for later implantation;
- alveolar ridge reconstruction for prosthetic treatment;
- filling of bone defects after root resection, cystectomy, removal of retained teeth;
- guided bone regeneration in dehiscence defects; and
- guided tissue regeneration procedures in periodontal defects.
SwissMembrane X Socket is intended for the following uses:
- augmentation around implants placed in immediate extraction sockets;
- augmentation around implants placed in delayed extraction sockets;
- localized ridge augmentation for later implantation;
- alveolar ridge reconstruction for prosthetic treatment;
- filling of bone defects after root resection, cystectomy, removal of retained teeth;
- guided bone regeneration in dehiscence defects.
SwissMembrane X and SwissMembrane X Socket are resorbable collagen membranes made of porcine collagen. The porous surface (facing the bone) allows the ingrowth of bone forming cells, and the dense surface (facing the soft tissue) prevents the ingrowth of fibrous connective tissue into the bone defect. The membranes are made of collagen without further cross-linking and are sterilized by gamma irradiation.
SwissMembrane X is provided in the following variants and sizes:
- SwissMembrane X D-Line
- 13 x 25 mm (rectangle)
- 25 x 15/25 mm (trapezoid)
- 30 x 25/40 mm (trapezoid)
- SwissMembrane X Socket D-Line
- 14 x 24 mm
The provided FDA 510(k) Clearance Letter for SwissMembrane X and SwissMembrane X Socket indicates that the device has been cleared based on substantial equivalence to a predicate device, Geistlich Bio-Gide® and Geistlich Bio-Gide® Shape (K212463).
This type of clearance (510(k)) generally means that the device does not require new detailed performance data to prove safety and effectiveness if it can demonstrate through comparison that it is as safe and effective as a legally marketed predicate device. Therefore, the document does not describe acceptance criteria for performance, nor does it detail a study proving device performance against specific metrics in the way one might expect for a novel device or a device involving an AI component.
The document explicitly states:
"Non-clinical data was not deemed necessary to support the extension to the product line. As the subject devices fall within the range of size configurations cleared under the predicate device, there is no new worst-case configuration."
"Results from biocompatibility, sterilization, shelf-life, packaging validation, bench and clinical performance studies from the applicant's own predicate device (K212463) were leveraged in support of substantial equivalence."
Because the clearance is based on substantial equivalence to an existing and already cleared device, the typical requirements for a new performance study with specific acceptance criteria, test sets, and ground truth establishment (as is common for AI/ML-driven devices or novel diagnostic tools) are not present or reported in this 510(k) summary.
Therefore, the following information cannot be extracted from this document as no new performance study, in the sense of demonstrating a device's de novo performance against predefined metrics, was conducted or reported for this submission.
Based on the provided document, the following information cannot be extracted for the reasons stated above:
-
A table of acceptance criteria and the reported device performance: Not applicable. Performance data against specific acceptance criteria for a new study is not provided, as substantial equivalence was based on the predicate device's data.
-
Sample sized used for the test set and the data provenance: Not applicable. No new test set for proving performance was described. The submission leveraged existing data from the predicate device.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. No new ground truth establishment process for a performance study is described.
-
Adjudication method for the test set: Not applicable. No new test set requiring adjudication is described.
-
If a multi-reader multi-case (MRMC) comparative effectiveness study was done: Not applicable. No MRMC study described. The device is a physical bone grafting material/membrane, not one that typically involves human readers assisted by AI.
-
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable. No algorithm is involved.
-
The type of ground truth used: Not applicable. No new performance study requiring independent ground truth is described.
-
The sample size for the training set: Not applicable. This is not an AI/ML device; therefore, no training set is relevant.
-
How the ground truth for the training set was established: Not applicable. No training set is relevant.
Summary of what the document DOES state regarding "performance data":
The "Performance Data" section (Page 7) explicitly states that "Non-clinical data was not deemed necessary to support the extension to the product line." It further clarifies that "Results from biocompatibility, sterilization, shelf-life, packaging validation, bench and clinical performance studies from the applicant's own predicate device (K212463) were leveraged in support of substantial equivalence."
This means the acceptance criteria and performance data for this particular 510(k) submission refer back to the studies and their results that supported the initial clearance of the predicate device (K212463). The current submission argues that since SwissMembrane X and SwissMembrane X Socket are essentially variants (different shapes and sizes within an existing range) of the already cleared predicate device, no new performance studies are required. They are considered "substantially equivalent" based on identical materials, manufacturing, sterilization, and similar use cases, and the safety and efficacy of the underlying technology have already been established by the predicate device's clearance.

-
filling of contained peri-implant defects of limited size to include 3-wall defects of a size up to 4 mm x 5 mm x 4 mm.
Geistlich Bio-Flow® is a flowable, sterile, biocompatible bone mineral plus collagen matrix consisting of Geistlich Bio-Oss® granules (K122894) and processed Geistlich Bio-Gide® collagen (K212463) in an 80:20 (dry weight) ratio. Geistlich Bio-Flow® is provided as dry granulated material pre-filled in a mixing syringe (0.2 cc or 0.5 cc fill volumes). Cannulas and a syringe for applying saline or blood to hydrate the product prior to extrusion are included with the product.
The provided text is a 510(k) Summary for a medical device (Geistlich Bio-Flow®), which focuses on demonstrating substantial equivalence to a predicate device rather than presenting a traditional clinical study with defined acceptance criteria and performance metrics for a diagnostic or AI-based device. This document describes the device, its intended use, and non-clinical performance data to support its safety and effectiveness. It does not contain an "acceptance criteria" table with specific thresholds or a detailed study of an AI device's performance against ground truth as would be found in a typical AI/diagnostic device submission.
However, I can extract the relevant information from the document that best approximates the requested points based on the nature of this submission. Since this is a bone grafting material, the "performance" is assessed through non-clinical (material characterization and animal) studies rather than a multi-reader, multi-case study, or standalone AI performance.
Here's an interpretation based on the provided text:
1. A table of acceptance criteria and the reported device performance
The document doesn't explicitly state quantitative acceptance criteria or a performance table in the format typically used for AI/diagnostic devices (e.g., sensitivity, specificity thresholds). Instead, "performance" is demonstrated through various non-clinical tests and a non-clinical animal study, with the overarching "acceptance criterion" being comparable performance to the predicate device in relevant biological and material characteristics.
Acceptance Criteria (Implied from the study's aim) | Reported Device Performance |
---|---|
Biocompatibility: Device demonstrates biological safety. | Positive: Biocompatibility Studies per ISO 10993-1:2018 (Cytotoxicity, Sensitization, Irritation/Intracutaneous Reactivity, Acute Systemic Toxicity, Material Mediated Pyrogenicity, Subacute Systemic Toxicity, Subchronic Systemic Toxicity, Chronic Systemic Toxicity, Implantation (local tissue reaction), Genotoxicity, Hemocompatibility) all performed and found acceptable (implied by clearance). |
Physical and Chemical Properties: Material characteristics are suitable for intended use. | Positive: Characterization of chemical properties (Chemical composition, Amino Acid Composition, Molecular Weight Distribution of Soluble Proteins, Enzymatic Collagen Degradation, Collagen Solubility) and physical properties (Porosity and morphology, Particle (Granule) Size, Volume Changes after Incubation) were performed. Characterization of Mineral Component (Bovine Bone Mineral) via FTIR spectroscopy and X-ray diffraction was performed. Outcomes are not explicitly detailed but are presumed acceptable for substantial equivalence. Handling and extrusion studies (Extrusion Force, Material Handling with Blood, Extrudable Volume, Organic and Inorganic Content of Extruded Material) were also performed successfully. |
Sterilization and Packaging: Device maintains sterility and integrity. | Positive: Sterilization Validation per ISO 11137-1:2006, ISO 11137-2:2013, and ISO 11137-3:2017. Packaging Validation per ISO 11607-1:2019, ASTM F1980:2007, ASTM F1886/F1886M:2016, ASTM F88:2015, ASTM F1929:2015, and ASTM F2096:2011. |
Stability: Device remains stable over shelf life. | Positive: Product stability testing per ICH Q1A(R2) and Collagen stability studies (Molecular Weight Distribution of Soluble Protein 18-months storage, Enzymatic Collagen Degradation 18-months storage, Collagen Solubility 18-months storage) were performed. |
Biological Performance (Animal Study): Device promotes bone regeneration and exhibits comparable resorption to predicate. | Positive: In a non-clinical animal performance study, no signs of adverse local tissue effects were observed with Geistlich Bio-Flow® at any time-point. At both 8 and 12 weeks, the bone substitute performance of the test and control groups (Geistlich Bio-Flow® vs. Geistlich Bio-Oss® Collagen) was comparable with respect to relevant parameters, such as Defect Fill Area, Bone Regeneration Height, and Bone-to-Granule-Contact. |
2. Sample size used for the test set and the data provenance
- Test Set (Animal Study): The document states "a non-clinical performance study was conducted to support the indications for use for the device," and "In a study assessing new bone growth and device resorption (4, 8, and 12 weeks), at both 8 and 12 weeks, the bone substitute performance of the test and control groups was comparable."
- Sample Size: The document does not specify the exact number of animals or defects studied.
- Data Provenance: Non-clinical (animal study). No country of origin is specified. It is a prospective study as it involved conducting tests with the device.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- This information is not applicable to this type of submission. The performance study was an animal model, not a human reader study requiring expert interpretation to establish ground truth for a diagnostic output.
4. Adjudication method for the test set
- This is not applicable as it was not a human reader study. The animal study results would likely be evaluated by veterinary histopathologists or researchers in a blinded manner, but no specific adjudication method (like 2+1) is mentioned.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, if so, what was the effect size of how much human readers improve with AI vs without AI assistance
- No, an MRMC comparative effectiveness study was not done. This device is a bone grafting material, not a diagnostic or AI-assisted device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- No, a standalone performance study in the context of an algorithm or AI was not done.
7. The type of ground truth used
- For the non-clinical performance study (animal study), the "ground truth" would be established by histological analysis (e.g., measurements of new bone formation, defect fill, and resorption characteristics) and potentially other quantitative analyses in the animal model. This falls under outcomes data simulation in an animal model.
8. The sample size for the training set
- This concept (training set) is not applicable to the evaluation of this bone grafting material. There is no AI model being trained.
9. How the ground truth for the training set was established
- This concept is not applicable as there is no AI model or training set.

Device 300397 Putty is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. Device 300397 Putty is indicated to be gently packed into bony voids or gaps of the skeletal system (i.e., posterolateral spine, ilium and pelvis). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. The product provides a bone void filler that resorbs and is replaced with bone during the healing process.
Device 300397 Putty must be used with blood or autogenous bone marrow aspirate and autograff in posterolateral spine.
Device 300397 Putty is an osteoconductive, porous, resorbable bone graft substitute which consists of calcium phosphate granules (a-TCP and hydroxyapatite) and Type I and III porcine collagen. The single-patient, single-use product is supplied in three (3) sizes as a sterile, dry block. When mixed with autogenous bone marrow aspirate, blood or sterile non-pyrogenic saline, the product forms a moldable non-setting putty (net volume: 2.5 cc, 5 cc or 10 cc).
The provided text is a 510(k) Summary for a medical device (Device 300397 Putty), which is a premarket notification for demonstrating substantial equivalence to a legally marketed predicate device. This type of submission focuses on comparing a new device to an existing one, rather than presenting a detailed clinical study with acceptance criteria, sample sizes, and ground truth establishment in the way typically seen for a novel diagnostic or AI device.
Therefore, the requested information components related to acceptance criteria, specific study design for proving acceptance criteria for an AI/diagnostic device, sample sizes for test/training sets, expert ground truth establishment, adjudication methods, MRMC studies, and standalone performance metrics are not applicable to this document.
This document describes a device approval process based on demonstrating substantial equivalence in terms of intended use, technological characteristics, and safety and performance through various tests, primarily non-clinical, not a study designed to meet specific performance metrics against a defined ground truth for a diagnostic outcome.
However, I can extract information regarding the safety and performance studies that were conducted to support the substantial equivalence claim.
Here's a summary based on the provided document, addressing the closest relevant points:
1. Acceptance Criteria and Reported Device Performance:
The document does not specify quantitative acceptance criteria in the manner of diagnostic performance metrics (e.g., sensitivity, specificity, AUC). Instead, the "acceptance criteria" are implicitly met by successful execution and favorable results of the numerous safety and performance tests to demonstrate substantial equivalence to the predicate device. The "reported device performance" is described qualitatively through these tests.
Category | Specific Test | Description of Performance (Implicitly Meets Acceptance) |
---|---|---|
Chemical Properties | Amino Acid Composition, Product Composition, Phase Analysis, FT-IR, SEM, Molecular Weight Distribution, Onset Temperature and Enthalpy of Protein Denaturation, Enzymatic Collagen Degradation | The device components (calcium phosphate granules, porcine collagen) were characterized. The use of a different TCP polymorph compared to the predicate was deemed not to raise different safety/effectiveness concerns due to similar structural composition and chemical stoichiometry. Identified raw material sources for porcine collagen were previously cleared. |
Physical Properties | Pore Size and Pore Size Distribution, Particle Size Distribution, Weight, Dimension, and Density, Determination of Hydrated Volume | Granule size is slightly larger than the predicate but demonstrated through performance testing not to raise new concerns. |
Material Handling | N/A (Studies Conducted) | N/A |
Sterilization | ISO 11137-1:2006, ISO 11137-2:2013, and ISO 11137-3:2017 | Validation successfully executed. |
Packaging | ISO 11607-1:2019, ASTM F1980:2007, ASTM F1886/F1886M:2016, ASTM F88:2015, ASTM F1929:2015, and ASTM F2096:2011 | Validation successfully executed. |
Product Stability | ICH Q1A(R2) | N/A (Studies Conducted) |
Transport Simulation | ISTA 3A | N/A (Studies Conducted) |
Biocompatibility | ISO 10993-1:2018 (comprising Cytotoxicity, Sensitization, Irritation/Intracutaneous Reactivity, Acute Systemic Toxicity, Material Mediated Pyrogenicity, Subacute Systemic Toxicity, Subchronic Systemic Toxicity, Genotoxicity, Implantation (local tissue reaction), Hemocompatibility, Chronic Systemic Toxicity, Elemental Impurities Analysis) | Successfully executed. Local tissue reaction was evaluated in accordance with ISO 10993-6:2016. |
In Vivo Performance | NZ White Rabbit Single Level Spinal Fusion Model | Device 300397 Putty hydrated with BMA or blood and mixed 1:1 with autograft demonstrated: |
- Progression in healing vs. time when implanted on decorticated transverse processes in the posterolateral space.
- Further healing at host decorticated transverse process interfaces with new bone formation and active osteoblasts.
- New bone formation directly on the graft material surfaces.
- Confirmed progression and maturation of fusions via histology.
- Bone remodeling and new marrow spaces at the decorticated host transverse process interface, with an association with a reduction in local inflammatory cells. Performance evaluated per FDA guidance for calcium salt bone void fillers. |
2. Sample Size and Data Provenance (for test set for AI/diagnostic devices):
- Not applicable for this 510(k) submission as it's not an AI/diagnostic device.
- For the in vivo animal study, the model used was the NZ White Rabbit Single Level Spinal Fusion Model. The specific number of animals is not provided in this summary. This is a prospective animal model study.
3. Number of Experts and Qualifications (for ground truth for AI/diagnostic devices):
- Not applicable as there is no mention of establishing ground truth by human experts for a diagnostic task.
- The evaluation of the in vivo study results (e.g., histology interpretation, assessment of bone formation) would typically be performed by veterinary pathologists or experts in orthopedics/bone regeneration, but their specific number and qualifications are not detailed in this summary.
4. Adjudication Method (for test set for AI/diagnostic devices):
- Not applicable for this type of device and submission.
5. MRMC Comparative Effectiveness Study:
- No, an MRMC comparative effectiveness study for human readers with and without AI assistance was not done, as this is not an AI/diagnostic device.
6. Standalone Performance Study:
- No, a standalone algorithm-only performance study was not done, as this is not an AI/diagnostic device.
- The "standalone" performance for this device is represented by the in vivo animal study where the device's ability to promote bone healing was directly assessed.
7. Type of Ground Truth Used:
- For the in vivo animal study, the "ground truth" for assessing bone healing and tissue reaction was based on histology (microscopic examination of tissue samples) and observation of fusion progression in the animal model. This could be considered similar to "pathology" for human studies, reflecting direct biological evidence of effect.
8. Sample Size for Training Set:
- Not applicable as this is not an AI/machine learning device that requires a training set.
9. How Ground Truth for Training Set Was Established:
- Not applicable as this is not an AI/machine learning device.

- Trauma wounds (abrasions, lacerations,second-degree burns, and skin tears)
- Draining wounds
- Tunneled/undermined wounds
The device is intended for one-time use.
Geistlich Wound Matrix PLUS is an animal-sourced, acellular extracellular matrix (ECM) wound dressing that is derived from porcine tissue. The porcine tissue undergoes processing to remove proteins and inactivate viruses. The device is intended for use in the management of wounds. Wound Matrix PLUS is terminally sterilized using gamma irradiation in its packaging.
The device is offered in various sizes and can be shaped to the required dimension using standard sterile instruments (scissors or scalpel).
The device is intended to be used by licensed healthcare practitioners and will be supplied sterile for single one-time use.
This appears to be an FDA 510(k) summary for a medical device called Geistlich Wound Matrix PLUS. It demonstrates substantial equivalence to a predicate device rather than presenting a study proving performance against specific acceptance criteria.
Therefore, the requested information cannot be fully extracted as such a study is not provided in this document. The document primarily focuses on demonstrating that the new device (Geistlich Wound Matrix PLUS) is as safe and effective as a legally marketed predicate device (ACell Inc.'s Cytal Wound Matrix) and a reference device (Geistlich Fibro-Gide) based on similar technological characteristics and performance data leveraged from the reference device.
However, I can extract information related to the performance data presented, which are mainly biocompatibility and viral inactivation studies, and explain why the other requested information is not applicable here.
Summary of Device Acceptance Information (Based on 510(k) Submission for Substantial Equivalence)
The provided document describes the Geistlich Wound Matrix PLUS seeking 510(k) clearance for substantial equivalence to a predicate device, ACell Inc.'s Cytal Wound Matrix (K152721), and referencing Geistlich Fibro-Gide (K171050) for performance data. This type of submission relies on demonstrating that the new device has similar technological characteristics and safety/effectiveness profiles to already cleared devices, rather than presenting a de novo study with explicit acceptance criteria for performance metrics like sensitivity or specificity.
1. A table of acceptance criteria and the reported device performance:
Since this is a 510(k) submission for substantial equivalence based on biocompatibility and viral inactivation leveraged from a reference device, there are no explicit "acceptance criteria" presented in the sense of performance thresholds for a diagnostic or AI device (e.g., minimum sensitivity, specificity, or AUC). Instead, the performance criteria are that the device demonstrates biocompatibility and viral safety.
Test (Standard) | Acceptance Criteria (Implied for 510(k)) | Reported Device Performance (Result for Wound Matrix PLUS / Fibro-Gide) |
---|---|---|
Cytotoxicity (ISO 10993-5) | Non-cytotoxic | Non-cytotoxic |
Irritation (ISO 10993-10) | Not irritant | Not irritant |
Sensitization (ISO 10993-10) | Not sensitizing | Not sensitizing |
Acute systemic toxicity (ISO 10993-11) | No acute systemic toxicity | No acute systemic toxicity |
Pyrogenicity (USP ) | Non-pyrogenic | Non-pyrogenic |
Genotoxicity (ISO 10993-3) | Non-mutagenic, Not genotoxic | Non-mutagenic, Not genotoxic |
Local tissue response (ISO 10993-6) | Acceptable local tissue response; No systemic toxicity | Local tissue effects: slight irritant. Systemic toxicity: No evidence of systemic toxicity |
Subchronic systemic toxicity (ISO 10993-11) | No subchronic toxicity | No subchronic toxicity |
Chronic systemic toxicity (ISO 10993-11) | No chronic toxicity | No chronic toxicity |
Chemical Characterization (ISO 10993-18) | No product-related semi-volatile organic compounds detected | No product-related semi-volatile organic compounds were detected |
Viral Inactivation (ISO 22442-3, ICH Q5A) | Support viral safety | Results support the viral safety of the device |
Expiration Dating / Shelf Life (ISO 11607) | Support intended shelf life | Product shelf life of three years supported |
Sterility Assurance Level (SAL) | SAL of 10-6 | SAL of 10-6 |
2. Sample size used for the test set and the data provenance:
- Sample size for Biocompatibility Tests: The specific number of animals or cell cultures used for each biocompatibility test (e.g., number of rabbits for irritation, guinea pigs for sensitization, mice for systemic toxicity, rats for implantation) is not explicitly stated in this summary. These are standard in vitro/in vivo biological tests.
- Data Provenance: The biocompatibility and viral inactivation testing "was leveraged from the previously reviewed and cleared reference device (Geistlich Fibro-Gide (K171050) that is identical in composition and technology to the subject device." This implies the tests were conducted with the Fibro-Gide device. The location or specific laboratory where these tests were performed is not mentioned, nor is whether the data was retrospective or prospective relative to the Fibro-Gide submission.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This is not applicable as the studies are focused on material properties (biocompatibility, viral safety, shelf life) and not on diagnostic accuracy requiring expert consensus or ground truth establishment in a clinical context.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- This is not applicable for biocompatibility and material property testing, which are lab-based assessments not requiring adjudication by experts.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- This is not applicable. Geistlich Wound Matrix PLUS is a wound dressing (a physical matrix), not an AI-assisted diagnostic or imaging device. Therefore, no MRMC study or human reader assistance analysis was performed.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- This is not applicable. The device is a wound dressing, not an algorithm or software. The performance data relates to its physical and biological properties.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- For biocompatibility tests, the "ground truth" is established by standard biological and chemical assays measuring specific toxicological endpoints (e.g., cell viability for cytotoxicity, inflammatory response for irritation, DNA damage for genotoxicity, systemic effects for toxicity tests).
- For viral inactivation, the ground truth relates to the measured reduction in viral titers.
- For shelf life, the ground truth is stability over time based on physical and functional properties.
8. The sample size for the training set:
- This is not applicable. There is no AI component or machine learning model that would require a "training set."
9. How the ground truth for the training set was established:
- This is not applicable, as there is no training set for this device.

Here's an analysis of the provided text regarding the acceptance criteria and supporting study for the Geistlich Bio-Gide family of devices.
Important Note: The provided document is an FDA 510(k) summary, which focuses on demonstrating "substantial equivalence" to a predicate device rather than presenting a detailed de novo device performance study with specific acceptance criteria and detailed clinical outcomes for a novel device. As such, direct "acceptance criteria" and "device performance" in a quantitative sense (like sensitivity/specificity targets) for a new algorithm are not explicitly stated in this type of document. Instead, the "acceptance criteria" here are implicitly meeting the performance characteristics and indications for use of the predicate device, backed by non-clinical and clinical data on the predicate.
Acceptance Criteria and Reported Device Performance
Acceptance Criteria (Implicit from Predicate Equivalence) | Reported Device Performance (Leveraged from Predicate Studies) |
---|---|
Material characteristics equivalent to predicate. | Identical (Porcine collagen) |
Manufacturing and sterilization methods equivalent to predicate. | Identical (Gamma sterilization) |
Packaging and size equivalent to predicate. | Similar sizes for Bio-Gide; identical for Bio-Gide Shape, Bio-Gide Compressed, Bio-Gide Perio, Combi-Kit Collagen, and Perio-System Combi-Pack |
Biocompatibility in accordance with ISO 10993-2018. | Leveraged from predicate (K192042), indicating compliance. |
Sterilization effectiveness (SAL) in accordance with ISO 11137-1:2006, ISO 11137-2:2013, ISO 11137-3:2017. | Leveraged from predicate (K192042), indicating compliance. |
Shelf-life stability equivalent to predicate. | Leveraged from predicate (K192042), indicating stability. |
Similar bench performance to predicate. | Leveraged from predicate (K192042), implying similar performance. |
Clinical performance for various dental defect types (e.g., bone growth, defect size reduction, alveolar ridge preservation). | "Complete wound closure is not required when used in extraction sites and alveolar ridge defects with an average vertical defect length and alveolar ridge width up to 5.7 mm and 18 mm, respectively. The Bio-Gide collagen membrane successfully performed its intended function by creating space to allow for vertical bone fill to occur and providing better alveolar ridge preservation compared to controls." (Based on 15 clinical studies involving 297 unique patients). |
Study Details
-
Sample Size used for the test set and the data provenance:
- Test Set Sample Size: 297 unique patients across 15 clinical studies.
- Data Provenance: Not explicitly stated (e.g., country of origin). The studies appear to be historical clinical studies from the applicant's predicate devices (K192042), making them retrospective in nature for this submission.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This information is not provided in the 510(k) summary. Given that the studies involved "evaluation for new bone growth and defect size" and "alveolar ridge preservation," the evaluations were likely performed by dental or oral surgery professionals, but their specific number or qualifications are not detailed.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- This information is not provided in the 510(k) summary.
-
If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No MRMC study was done. This is a medical device submission for a physical bone grafting material/membrane, not an AI or imaging diagnostic device that would involve human readers or AI assistance in interpretation.
-
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is not an algorithm or AI device.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- The ground truth appears to be clinical outcomes data from human patients, including measurements of new bone growth, defect size reduction, and alveolar ridge preservation. These outcomes would have been evaluated by clinicians, potentially by consensus or standardized measurement protocols, but the specifics are not detailed.
-
The sample size for the training set:
- Not applicable. This is not a machine learning or AI device that requires a training set. The "performance data" section leveraged historical clinical studies from the predicate device as evidence of safety and effectiveness for the subject device.
-
How the ground truth for the training set was established:
- Not applicable. See point 7.
