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

Study Details

1. 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.

2. 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.

3. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

   • This information is not provided in the 510(k) summary.

4. 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.

5. 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.

6. 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.

7. 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.

8. How the ground truth for the training set was established:

   • Not applicable. See point 7.

Here's an analysis of the acceptance criteria and supporting study details based on the provided document:

1. Table of Acceptance Criteria and Reported Device Performance

For all listed devices (Geistlich Bio-Gide®, Geistlich Bio-Gide® Shape, Geistlich Bio-Gide® Compressed, Geistlich Bio-Gide® Perio, Geistlich Combi-Kit Collagen, Geistlich Perio-System Combi-Pack, Geistlich Mucograft® and Geistlich Mucograft® Seal), the acceptance criteria are not explicitly stated as numerical thresholds. Instead, the criterion for acceptance is that the material properties remain unchanged when using an alternate supplier of porcine raw material compared to the predicate devices. The reported device performance is that these properties did remain unchanged.

Specific Performance Studies Conducted:

• Elongation: Verified to be unchanged.
• Suture pull-out test: Verified to be unchanged.
• Swelling: Verified to be unchanged.
• Differential Scanning Calorimetry (DSC): Verified to be unchanged.
• Collagenase digestion (to assess degradation): Verified to be unchanged.
• Scanning Electron Microscopy (SEM) (to assess optical differences): Verified to be unchanged.
• Viral safety evaluation per ICH Q5A(R1) and ISO 22442-3:2007: Verified (leveraged from K171050).
• Biocompatibility, sterilization, shelf-life, and clinical performance: Leveraged from the applicant's own predicate devices, implying these aspects also remained consistent.

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the numerical sample size for "test sets" in the traditional sense of a clinical trial. Instead, the performance studies were conducted on "representative product" for each device to verify material properties. The provenance of this "representative product" is not specified (e.g., country of origin). The studies appear to be laboratory-based and not involving patient data, so the terms "retrospective" or "prospective" are not applicable.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

This information is not provided in the document. The studies performed are physical and chemical characterizations of the material, not clinical evaluations requiring expert interpretation of results. The "ground truth" for these tests would be the established scientific methods and parameters for each test.

4. Adjudication Method for the Test Set

This information is not provided. Given the nature of the physical and chemical tests, it's unlikely a human-based adjudication method (like 2+1 or 3+1) would be used. The results of these tests are typically objectively measured and compared to established specifications or to the predicate device's performance.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No, an MRMC comparative effectiveness study was not done. This submission is for a material change (alternate raw material supplier) and not a new diagnostic or therapeutic device requiring human interpretation of results.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

This question is not applicable. The device is a physical bone grafting material/membrane, not a software algorithm.

7. The Type of Ground Truth Used

The ground truth used for these studies is based on objective physical and chemical material properties and standards. The performance of the modified devices (with the alternate raw material supplier) was compared to the known performance and characteristics of the predicate devices. The determination of "unchanged" would rely on laboratory measurements meeting predefined specifications or falling within an acceptable range relative to the predicate device.

8. The Sample Size for the Training Set

This question is not applicable. This submission is about a physical medical device and a change in its raw material supplier. There is no machine learning model or "training set" involved.

9. How the Ground Truth for the Training Set Was Established

This question is not applicable, as there is no training set for an AI/ML model.

Geistlich Bio-Gide® Shape is a pure collagen membrane with a bilayer structure. The porous surface (facing the bone) allows the ingrowth of bone forming cells into the membrane, and the dense surface (facing the soft tissue) prevents the ingrowth of fibrous connective tissue into the bone defect. The membrane is made of collagen without further cross-linking, and is sterilized by gamma irradiation. The Geistlich Bio-Gide® Shape membrane has a pre-shaped form with a maximum width and height of 14mm x 24mm, respectively. With the exception of the size and shape, Geistlich Bio-Gide® Shape is the same as its predicate device, Geistlich Bio-Gide® Perio (K112575).

Geistlich Bio-Gide® Compressed is a pure collagen membrane with a bilayer structure. The porous surface (facing the bone) allows the ingrowth of bone forming cells into the membrane, and the dense surface (facing the soft tissue) prevents the ingrowth of fibrous connective tissue into the bone defect. The membrane is made of collagen without further cross-linking, and is sterilized by gamma irradiation. The Geistlich Bio-Gide® Compressed membrane is available in two different sizes, 13 x 25 mm and 20 x 30 mm. With the exception of the size and a minor difference during manufacturing to mark the dense surface of the membrane, which should face the soft tissue, Geistlich Bio-Gide® Compressed is the same as its predicate device, Geistlich Bio-Gide® Perio.

The provided text describes Geistlich Bio-Gide® Shape and Geistlich Bio-Gide® Compressed, which are collagen membranes used as bone grafting materials. The 510(k) submission argues for their substantial equivalence to predicate devices, rather than establishing acceptance criteria for a new device's performance metrics. As such, explicit acceptance criteria with numerical targets and a study designed to prove the device meets those new acceptance criteria (as would be typical for novel devices with distinct performance claims) are not presented in this document.

Instead, the documentation focuses on demonstrating that the new devices are substantially equivalent to existing legally marketed predicate devices by showing they have:

• The same intended use.
• Similar technological characteristics.
• Similar performance and safety profiles.

The "studies" described are primarily to support this claim of substantial equivalence by showing that material properties, biocompatibility, and clinical outcomes are consistent with the predicate and reference devices.

Therefore, for this specific submission:

1. Table of Acceptance Criteria and Reported Device Performance:

Since the submission is for substantial equivalence, formal acceptance criteria in the traditional sense of a new performance threshold are not explicitly stated for Geistlich Bio-Gide® Shape or Geistlich Bio-Gide® Compressed. Instead, the "acceptance criteria" are implied to be "demonstrates substantial equivalence to the predicate device" based on the following characteristics and their performance relative to the predicate:

2. Sample Size Used for the Test Set and Data Provenance:

• Geistlich Bio-Gide® Shape & Compressed (for testing against predicate):
  • Test Set Sample Size: Not applicable in the context of a new efficacy study. The "test set" here refers to the actual manufactured devices (Geistlich Bio-Gide® Shape and Compressed) subjected to physical/chemical, sterility, biocompatibility, and usability testing to confirm they meet specifications and are comparable to the predicate. The exact number of units tested for each characteristic is not specified.
  • Data Provenance: The manufacturing and testing data are from Geistlich Pharma AG, Switzerland. This is directly related to the newly submitted devices.
• Clinical Data (from reference devices):
  • An animal study related to Geistlich Bio-Gide® (K960724).
  • A clinical study of 75 patients examining Geistlich Bio-Gide® as a barrier membrane for guided bone regeneration in simultaneous implant placement.
  • Another clinical study involving 15 patients and 16 Geistlich Bio-Gide membranes for defect filling.
  • Several clinical studies on Geistlich Bio-Gide® for guided tissue regeneration procedures in periodontal defects:
    • Recession defects: 20 patients (pairs of defects).
    • Furcation defects: 52 grade II mandibular molar furcation defects; 21 patients with 31 furcation defects.
    • Intrabony defects: 22 paired intrabony defects; 28 patients (each with one intrabony defect); 124 patients (each with at least one intrabony defect); two studies with 4 intrabony defects each.
  • Data Provenance for Clinical Studies: The specific countries of origin for these clinical studies are not provided in the document. They are generally referenced as "clinical testing data from the K960724 and K042197 reference devices," implying these studies were conducted prior to this submission and are being cited to support the equivalence claim. The studies appear to be prospective clinical trials assessing the performance of the reference device.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:

• Not directly applicable. "Ground truth" in this context would typically refer to a definitive diagnosis or outcome for a diagnostic device. For these devices (bone grafting materials), the assessment criteria are objective (e.g., meeting chemical specifications, biocompatibility, histological evaluation in animal models, and clinical outcomes reported in existing literature).
• The clinical studies referenced would have involved clinicians (dentists, periodontists) who assessed the outcomes and established the "truth" for those studies. However, the exact number and qualifications of these experts are not provided in this summary.

4. Adjudication Method for the Test Set:

• Not applicable as this is not a diagnostic device requiring human adjudication in the described testing. Assessment involves laboratory tests, biocompatibility assays, and clinical outcomes from human studies, not consensus of human readers on images or test results.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

• No, a MRMC comparative effectiveness study was not done. This type of study is typically associated with diagnostic imaging devices where human readers interpret medical images with and without AI assistance to measure improvements in diagnostic accuracy or efficiency.

6. Standalone Performance (Algorithm Only without Human-in-the-Loop Performance):

• Not applicable. These devices are physical materials (collagen membranes) for bone grafting, not algorithms or software. Their performance is assessed through material properties, biocompatibility, and clinical outcomes, not as a standalone algorithm.

7. Type of Ground Truth Used:

• For material and biocompatibility testing: Laboratory Assay Results, Chemical Specifications, Histological Evaluation (animal study).
• For clinical studies (referenced for Geistlich Bio-Gide® family): Clinical Outcomes (e.g., gain of root coverage, decrease of recess depth, pocket reduction, gain in clinical attachment level (CAL), vertical/horizontal defect fill, radiographic appearance, and histological evaluation in some cases), and Safety Data (adverse events). These are objective clinical measurements and observations.

8. Sample Size for the Training Set:

• Not applicable. These are physical medical devices, not AI/ML algorithms that require training sets. The "training" for these devices would be the extensive research and development and prior clinical experience with similar collagen membranes.

9. How the Ground Truth for the Training Set Was Established:

• Not applicable, as this is not an AI/ML device that uses a training set.
