This document is a 510(k) clearance letter for a bone screw, not a study evaluating an AI/software as a medical device (SaMD). Therefore, the provided text does not contain the information requested in your prompt regarding acceptance criteria and studies proving device performance for an AI/SaMD.
The 510(k) summary focuses on demonstrating "substantial equivalence" of the new Bone Screw device to existing predicate devices based on:
- Indications for Use: The new device has the same intended use as the predicate.
- Technological Characteristics: Similarities in material (Titanium Alloy), manufacturing process (machined), design, and sterilization method (Gamma Irradiation).
- Performance Testing: Non-clinical tests (Driving Torque, Axial Pullout Strength, Torsional Strength) were conducted to show the new device performs comparably to the predicate, especially regarding a new smaller thread diameter.
- Biocompatibility and Shelf-life: Leveraged data from the predicate device due to material and packaging similarities.
- MR Compatibility: Assessed using scientific rationale and published literature, not a study with acceptance criteria.
Therefore, I cannot extract the requested information as it pertains to an AI/SaMD from this document.

Device Name:** USTOMED Bone Fixation/Bone Augmentation Systems - PIN
Regulation Number: 21 CFR 872.4880
Systems - PIN
Common Name: Pin
Product Codes: DZL Intraosseous Fixation Screw or Wire, Reg. #872.4880
USTOMED Bone Fixation/Bone Augmentation Systems – PIN is intended for fastening membranes during bone regenerative treatment.
USTOMED Bone Fixation/Bone Augmentation Systems – PIN consists of a titanium pin. The Pin can be used to fasten third-party non-absorbable PTFE and titanium-reinforced membranes up to a thickness of 1.0mm cleared by FDA for stabilization and support of bone grafts in dento-alveolar bony defect sites (product code JEY). After fulfilling its supportive function, which is typically achieved within three to nine months, the Pin must be removed, as it is not intended to remain in the body permanently.
The Pin are intended for single use and provided non-sterile for cleaning and sterilization by the user before use.
This 510(k) clearance letter pertains to a Class II medical device, the USTOMED Bone Fixation/Bone Augmentation Systems - PIN. The letter states that the device has been found substantially equivalent to a predicate device (NEOSS Ltd.'s Membrane Tack, K201561).
The information provided in this 510(k) summary focuses primarily on demonstrating substantial equivalence through a comparison of technological characteristics and performance testing to ensure the device meets established safety and performance standards. It does not describe a clinical study of diagnostic performance, but rather engineering and material tests typical for an implantable device with a mechanical function.
However, based on the provided text, we can describe the acceptance criteria and study that proves the device meets those criteria:
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria | Reported Device Performance |
---|---|
Dimensional Verification of Specifications Met | Acceptance criteria were met for all tests performed. |
Validation Testing of Recommended End User Device Reprocessing Procedures | Acceptance criteria were met for all tests performed. |
Mechanical Testing in Accordance with ASTM F543-17 | Acceptance criteria were met for all tests performed. |
Evaluation of Biocompatibility in Accordance with ISO 10993-1 | Acceptance criteria were met for all tests performed. |
Cytotoxicity in Accordance with ISO 10993-5 | Acceptance criteria were met for all tests performed. |
Materials Chemical Analysis in Accordance with ISO 10993-18 | Acceptance criteria were met for all tests performed. |
2. Sample Size Used for the Test Set and Data Provenance
The document does not specify the exact sample sizes for each test mentioned (dimensional verification, reprocessing validation, mechanical testing, biocompatibility, cytotoxicity, materials chemical analysis). These are likely engineering and laboratory tests, not clinical trials with patient data. Therefore, "data provenance" in terms of country of origin of patient data or retrospective/prospective is not applicable to these types of tests. The data provenance would be laboratory testing conducted by the manufacturer or a contracted lab.
3. Number of Experts Used to Establish Ground Truth and Their Qualifications
This information is not applicable to the types of tests described. These are not diagnostic accuracy studies requiring expert reads of images or clinical assessments to establish ground truth. The "ground truth" for these tests is established by the specifications and standards (e.g., ASTM F543-17, ISO 10993).
4. Adjudication Method for the Test Set
Not applicable. The tests described are laboratory and engineering tests with objective pass/fail criteria based on established standards, not subjective assessments requiring expert adjudication.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No. An MRMC study is relevant for diagnostic devices where human readers interpret medical images or data, often with and without AI assistance, to assess changes in diagnostic performance. This device is a bone fixation pin and therefore, this type of study is not relevant for its clearance.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Yes, in a sense. The "performance testing" described (dimensional verification, mechanical testing, biocompatibility, etc.) are all standalone tests of the device's physical and material properties, independent of human interaction during testing, beyond setting up the experiment. This device is not an AI algorithm, so the term "algorithm only" is not directly applicable.
7. The Type of Ground Truth Used
The ground truth for these performance tests is based on engineering specifications, material science standards (e.g., ISO 10993, ASTM F543-17), and documented reprocessing protocols. For example, for dimensional verification, the ground truth is the specified dimensions from the device design. For mechanical testing, the ground truth is the expected mechanical properties as defined by the ASTM standard for a similar device. For biocompatibility, the ground truth is the absence of adverse biological reactions as defined by ISO standards.
8. The Sample Size for the Training Set
Not applicable. This device is a physical medical device, not an AI/ML algorithm that requires a "training set" of data.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this type of device.

Pin with a flat head for the fixation of resorbable and non-resorbable membranes.
This is a 510(k) summary for a medical device (MP Pin without thread, flat head) which is seeking substantial equivalence to a predicate device. This type of submission relies on demonstrating that the new device is as safe and effective as a legally marketed predicate device, rather than proving efficacy in the way a pharmaceutical might.
Therefore, the requested information, which is typically associated with clinical trials, statistical performance metrics, and AI/software device studies, is largely not applicable or present in this document.
Here's an breakdown based on the provided text, addressing why some information is absent:
1. A table of acceptance criteria and the reported device performance
The document does not specify formal "acceptance criteria" in the sense of performance metrics (e.g., sensitivity, specificity, accuracy) that an AI or diagnostic device would undergo. Instead, substantial equivalence is based on:
Acceptance Criterion (Implicit for 510(k)) | Reported Device Performance (from document) |
---|---|
Intended Use/Indications for Use: Identical to predicate device | The MP Pins without thread, flat head are indicated for the fixation of apical membrane ends at the local bone in order to avoid micromobility of the membrane. They allow for the fixation of resorbable and non-resorbable membranes. (Identical to predicate) |
Material: Same as predicate device | Composed of the same titanium alloy (3.7165 6Al-4V ELI) as the predicate device. |
Principle of Operation: Identical to predicate device | Identical principles of operation (i.e., the fixation of resorbable and non-resorbable membranes). |
Safety - Biocompatibility: No cytotoxicity observed | Cytotoxicity testing per ISO 10993-5 showed results confirming biological safety. |
Safety - Sterilization: Validated as per standard | Sterilization validation performed per ISO 17664 and ISO 17665-1. |
Safety - New Risks: No new risks identified compared to predicate | Differences in dimensions due to pin head geometry (flat head vs. hexagonal) do not raise new risks with regard to safety or performance, as determined by internal validation based on IEC 62366-1. |
2. Sample size used for the test set and the data provenance
This information is not applicable as this submission is for a mechanical medical device (a pin) and does not involve AI or software that would typically have a "test set" of patient data. The "performance data" refers to standard mechanical and biological testing.
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 for the reasons stated above.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This information is not applicable for the reasons stated above.
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 information is not applicable as this device is a physical medical pin and does not involve AI assistance for human readers.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This information is not applicable as this device is a physical medical pin and does not involve an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the biocompatibility testing, the "ground truth" would be the standard biological response according to ISO 10993-5, where the absence of cytotoxicity is the desired outcome. For sterilization, the "ground truth" is compliance with the specified ISO standards for sterility. For mechanical and dimensional evaluation, the "ground truth" relates to engineering specifications and comparison to the predicate device's design, assessed through internal validation.
8. The sample size for the training set
This information is not applicable as this submission is for a mechanical medical device and does not involve a "training set" in the context of machine learning or AI.
9. How the ground truth for the training set was established
This information is not applicable for the reasons stated above.
In summary: The provided document is a 510(k) summary for a physical medical device. The "study" proving it meets acceptance criteria consists of standard engineering, biocompatibility, and sterilization testing, not clinical trials or AI performance evaluations as would be implied by many of the questions. The acceptance criteria are primarily focused on demonstrating substantial equivalence to a predicate device in terms of intended use, materials, fundamental operation, and safety.

The document describes the KLS Martin Oral-Max Implants - MR Conditional, a bundled submission of various osteosynthesis systems and screws intended for use in craniomaxillofacial surgery. The purpose of this submission is to support the conditional safety and labeling modification of these devices in the magnetic resonance (MR) environment.
Here's an analysis of the acceptance criteria and the study that proves the device meets them:
1. A table of acceptance criteria and the reported device performance
The acceptance criteria are implied by the non-clinical tests conducted to support MR Conditional safety, aligning with relevant ASTM standards and FDA guidance. The reported device performance is that the devices can be safely scanned under specified conditions.
Acceptance Criteria (from ASTM/FDA Guidance) | Reported Device Performance (Summary from Submission) |
---|---|
Magnetically induced displacement force within acceptable limits (ASTM F2052-21) | Not explicitly quantified but implied as acceptable for MR Conditional labeling. |
Magnetically induced torque within acceptable limits (ASTM F2213-17) | Not explicitly quantified but implied as acceptable for MR Conditional labeling. |
Image artifacts within acceptable limits (ASTM F2119-07, R2013) | Not explicitly quantified but implied as acceptable for MR Conditional labeling. |
RF-induced heating (ASTM F2182-19e2) resulting in a temperature rise below 6 ℃ | Achieved under specified scanning conditions: 1.5 T/64 MHz and 3 T/128 MHz at a whole-body averaged specific absorption rate (wbSAR) of 2 W/kg or head SAR of 3.2 W/kg for an hour-long scanning session. |
2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)
The testing involved computational modeling and simulation (CM&S). The "test set" in this context refers to the simulated scenarios and device configurations.
- Sample Size for Test Set: "the entire portfolio of KLS Martin maxillofacial implants" was simulated. This implies that all devices grouped under "KLS Martin Oral-Max Implants - MR Conditional" were included in the simulations. The document also mentions "various in-vivo device positions and landmarks," "worst-case single and multiple devices," and simulations in "10 cm increments." This suggests a comprehensive set of simulated scenarios rather than a traditional physical sample size.
- Data Provenance: Not explicitly stated as "country of origin" or "retrospective/prospective" in the same way clinical data is. The data is generated through computational modeling and simulation using MED Institute's FDA-qualified Medical Device Development Tool (MDDT) and the Duke virtual human anatomy. This is a form of prospective simulation data.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable in the traditional sense for this type of non-clinical, simulation-based study. The "ground truth" for the RF-induced heating simulations is derived from the established physics and engineering principles embedded in the FDA-qualified MDDT and the Duke virtual human anatomy model. The expertise lies in the development and validation of these computational tools and the interpretation of the simulation results by experts in MR safety and medical device engineering at MED Institute and the submitting company. The document does not specify the number or qualifications of individual experts validating the computational model, but implies that the MDDT itself is "FDA-qualified," indicating a level of expert review and agreement on its methodology.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set
Not applicable. Adjudication methods like "2+1" or "3+1" are typically used for consensus building among human expert readers for clinical studies, especially when establishing ground truth from image interpretation. This study is based on physical property testing and computational simulations, not human interpretation of clinical data.
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 a study involving human readers or AI-assisted diagnostic performance. It focuses on the physical safety of implants in an MR environment.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
The RF-induced heating assessment involved "Computational modeling and simulation (CM&S) ... using MED Institute's FDA-qualified Medical Device Development Tool (MDDT) and in a clinically relevant position within the Duke virtual human anatomy." This is a standalone algorithm/model-based assessment without a human-in-the-loop for the performance evaluation itself. Human experts design the simulations, configure the models, and interpret the results, but the "performance" (temperature rise, SAR calculations) is computed by the algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
For the non-clinical tests:
- Magnetically induced displacement force, torque, and image artifacts: The "ground truth" is based on the physical properties of the materials and device designs, measured or calculated according to established ASTM standards (F2052-21, F2213-17, F2119-07).
- RF-induced heating: The "ground truth" for the simulations is derived from the established electromagnetic physics and thermal dynamics principles implemented in the FDA-qualified Medical Device Development Tool (MDDT) and applied to the Duke virtual human anatomy model. The MDDT's qualification process by the FDA implicitly establishes the reliability of its results as a form of "ground truth" for simulation-based assessments.
8. The sample size for the training set
Not applicable. This is a non-clinical study for MR safety assessment, not a machine learning model requiring a training set in the typical sense. The "training" for the MDDT is its initial validation and qualification against known physical phenomena and experimental data, which is a separate process from this submission.
9. How the ground truth for the training set was established
Not applicable, as there is no training set for a machine learning model in this context. The "ground truth" for qualifying the simulation tool (MDDT) would have been established through extensive validation against experimental measurements and recognized physical theories.

Trade/Device Name: SAVE GBR Regulation Number: 21 CFR 872.4880
Product Code: DZL
- Panel: Dental
- Regulation Number: 872.4880
- Device Class: Class II
- .
The device is intended for use in stabilizing and fixating bone filling material and/or barrier membranes used for guided bone/tissue regeneration in the oral cavity. Single patient use only.
SAVE GBR is manufactured by Ti-6Al-4V ELI. The SAVE GBR is composed of GBR Screw and Bone Tack and these screws and tacks are used to fix barrier membranes in bone regeneration procedures.
The diameter of the GBR screw is 1.4 and length is 3.9, 4.38, 5.9, 6.38, 7.9 and 8.38mm. The diameter of the Bone Tack is 2.5 and length is 2.6 and 4.1mm.
These screws and tacks are implanted for a maximum duration of 6 months. The SAVE GBR is provided sterile.
The subject device is compatible with the OssBuilder membrane cleared in K172354.
The provided document is a 510(k) premarket notification for the "SAVE GBR" device, which is an intraosseous fixation screw or wire used in guided bone/tissue regeneration in the oral cavity. This document focuses on demonstrating substantial equivalence to predicate devices rather than proving the device meets specific acceptance criteria through a standalone clinical study.
Therefore, much of the requested information regarding "acceptance criteria and the study that proves the device meets the acceptance criteria" in terms of clinical performance metrics (like sensitivity, specificity, accuracy, or human reader improvement with AI) is not applicable to this type of regulatory submission.
The document describes non-clinical testing performed to demonstrate the safety and effectiveness of the device compared to its predicates. The "acceptance criteria" here are typically compliance with relevant international standards and equivalence to predicate devices in terms of material, design, and performance characteristics.
Here’s a breakdown of the information that can be extracted from the provided text, addressing the points where applicable:
1. Table of Acceptance Criteria and Reported Device Performance
Note: The FDA 510(k) process for this device type doesn't establish numerical "performance" criteria in the way a diagnostic AI device might have sensitivity/specificity targets. Instead, "acceptance criteria" are compliance with standards and demonstration of equivalence to legally marketed predicates. The "reported device performance" reflects how the device met these engineering and material standards.
Acceptance Criterion (Standard/Requirement) | Reported Device Performance / Assessment |
---|---|
Material Composition | Ti-6Al-4V ELI (ASTM F136 compliant) |
Biocompatibility | Demonstrates biocompatibility (leveraged results from K210080 due to same material/manufacturing) |
Sterilization | Gamma Sterilization (ISO 11137-1, ISO 11137-2 compliant) |
Shelf Life | 8 years (ASTM F1980-07 compliant) |
Packaging | Compliant with relevant standards |
Bacterial Endotoxin Test | Compliant (ANSI/AAMI ST72:2011, USP , USP referenced) |
Mechanical Properties (GBR screw): | Torsion: Conducted |
Driving Torque: Conducted | |
Axial Pullout Strength: Conducted (ISO 19023, ASTM F543-17 compliant) | |
Mechanical Properties (Bone Tack): | Torsion: Conducted |
Axial Pullout Strength: Conducted | |
MR Environment Condition | Evaluated using scientific rationale and published literature per FDA guidance. |
Substantial Equivalence (GBR Screw) | Demonstrated to K170697 (Primary Predicate) and K182881 (Reference Device) in dimensions, material, indications, and technological characteristics. Differences in screw design, anodizing, and sterilization addressed. |
Substantial Equivalence (Bone Tack) | Demonstrated to K170697 (Primary Predicate) and K182881 (Reference Device) in designs, material, indications, and technological characteristics. Difference in sterilization addressed. |
The following questions are not applicable to this 510(k) submission as it concerns a physical medical device (implants) and not a diagnostic or AI-driven system that would typically undergo such evaluations.
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. This document describes non-clinical (biocompatibility, mechanical, sterilization) testing of a physical implant device, not a diagnostic algorithm tested on a dataset of patient cases.
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. Ground truth for a diagnostic algorithm is not relevant here. The ground truth for device safety and performance relies on validated laboratory methods and engineering standards.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not Applicable. This pertains to expert review of diagnostic cases, which is not relevant for this physical 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. MRMC studies are for diagnostic interpretation improvement with AI. This document is for a physical implantable device.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
- Not Applicable. This refers to the performance of an algorithm; it is not relevant for this physical device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- The "ground truth" for this device's regulatory clearance is compliance with recognized international standards (e.g., ISO, ASTM for materials, sterilization, mechanical properties) and demonstration of substantial equivalence to legally marketed predicate devices through comparative testing and analysis. This is based on objective measurements and verified material properties, not clinical expert consensus on diagnostic images or patient outcomes.
8. The sample size for the training set
- Not Applicable. There is no "training set" in the context of an AI algorithm for this device. Testing involves samples of the physical device for non-clinical evaluations.
9. How the ground truth for the training set was established
- Not Applicable. No training set; ground truth is established by engineering and materials science standards.

Trade/Device Name: Micro Screw System, Micro Screw System Basic Regulation Number: 21 CFR 872.4880
|
| Product Code: | DZL |
| Regulation No: | 872.4880
The Micro Screw System, Micro Screw System Basic are developed and manufactured to be used as non-active bone surgery implants for the treatment of bone fractures, especially for the fixation of transplanted bone blocks during the augmentation process in the oral cavity and maxillomandibular surgical field. Note: Micro Screws are not intended to remain in the body permanently. After they have fulfilled their supportive function such as is the case after healing of a transplant, or healing of a fracture, for example, they need to be removed completely.
The Micro Screw System, Micro Screw System Basic are used for the safe fixation and stabilisation of cortical bone grafts. These systems contain osteosynthesis screws made of surgical stainless steel with diameters of 1.0 mm and 1.2 mm.
This is a 510(k) premarket notification for a medical device called the "Micro Screw System, Micro Screw System Basic". This type of submission is for demonstrating substantial equivalence to a legally marketed predicate device, rather than proving safety and effectiveness through clinical trials with specific acceptance criteria in the same way a PMA (Premarket Approval) would.
Therefore, the structure of the response will be different as the document does not contain information about a study designed to meet specific performance acceptance criteria in the typical sense for an AI/ML device. Instead, the "study" is a set of non-clinical bench tests comparing the new device to a predicate device to show equivalence.
Here's an analysis based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance
Since this is a 510(k) for a physical medical device (micro screws), the "acceptance criteria" are primarily established by recognized standards and requirements for substantial equivalence to a predicate device, rather than explicit numerical performance targets like sensitivity/specificity for an AI system. The "reported device performance" are the results of bench tests demonstrating compliance with these standards and comparability to the predicate.
Acceptance Criteria Category (implied by standards & predicate comparison) | Reported Device Performance (Micro Screw System, Micro Screw System Basic) |
---|---|
Material Properties: | |
- Standard for Wrought Stainless Steel (ASTM F138, ISO 5832-1) | Meets ASTM F138 (UNS S31673) and ISO 5832-1. Same material as predicate. |
- Biocompatibility (ISO 10993-1, -5, ISO 7405) | Biocompatibility risk assessment conducted. Shown non-cytotoxic. Similar material/manufacturing as predicate. Safe regarding auxiliary substances. |
Mechanical Performance (ASTM F543-17): | |
- Torsional Properties (yield strength, max torque, breaking angle) | Higher insertion torques, higher maximal torque, comparable final ratio (~9 vs. ~10). Breaking angle equivalent to predicate. Ductility acceptable. |
- Driving Torque | Substantially equivalent to predicate. |
- Axial Pullout Strength | Comparable values to predicate. |
Sterilization: | |
- Validation according to ISO 17664, 17665-1, 11737-1/2, AAMI ST79/ST81, ISO 14937, DIN EN 868-2. | Successfully steam sterilized in 3 independent cycles following reprocessing instructions. |
Shelf-life: | Delivered non-sterile (same as predicate). |
Design: (Implicit comparison to predicate) | Self-tapping thread, cylindrical shank, atraumatic apex, flat drill head with square bore, smooth screw surface for simple removal. (Similar to predicate). |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: The document does not specify a numerical sample size for the mechanical performance tests (e.g., how many screws were tested for torsional properties). It mentions "Several performance tests have been performed."
- Data Provenance: The tests are "Non-Clinical Bench Testing" conducted by the manufacturer, Hager & Meisinger GmbH. The country of origin for the data is Germany (where the company is based), but the standards used are international (ASTM, ISO, AAMI, DIN EN). This is retrospective data, as it describes tests already performed.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
This information is not applicable in the context of this 510(k) submission for a physical device. Ground truth for mechanical properties is established through standardized physical measurements and material science, not human expert consensus.
4. Adjudication Method for the Test Set
Not applicable. Adjudication methods like 2+1 or 3+1 are used for expert consensus in clinical studies, particularly for AI/ML performance evaluation, not for physical device bench testing.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size
Not applicable. This is not an AI/ML device, and an MRMC study is relevant for evaluating the impact of AI on human reader performance, which isn't the scope of this submission.
6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study Was Done
Not applicable. This device does not involve an algorithm.
7. The Type of Ground Truth Used
The "ground truth" for this device's evaluation is primarily:
- Physical Measurements: Directly measured properties like torque, angle, and pullout force.
- Material Standards Compliance: Verification against established chemical and mechanical specifications for surgical stainless steel (e.g., composition, strength).
- Biological Standards Compliance: Verification against established ISO standards for biocompatibility, typically involving in-vitro tests (e.g., cytotoxicity) and risk assessments.
- Predicate Device Data: Performance characteristics of the previously cleared predicate device (K080430, STOMA Bone Block Screw) serve as a de facto "ground truth" for demonstrating substantial equivalence.
8. The Sample Size for the Training Set
Not applicable. This is not an AI/ML device, so there is no training set in the sense of machine learning.
9. How the Ground Truth for the Training Set Was Established
Not applicable. There is no training set.

The Biomet Microfixation OmniMax MMF System is indication of mandibular and maxillary fractures to maintain proper occlusion during surgery and for post-operative fracture healing in adults and adolescents (age 12 and older) in whom permanent teeth have erupted.
The Biomet Microfixation OmniMax MMF System is composed of metallic plates (arch bars) and locking screws that provide temporary stabilization of mandibular and maxillary bone during fracture healing and/or temporarily maintain a stable occlusion during surgery. Mandibular and Maxillary Fixation (MMF) is achieved through application of fixation plates and locking screws to bone; wire or elastics are then secured around hooks.
The OmniMax MMF system includes a fixation plate (also known as an arch bar) that has an in-plane bend to provide an initial approximation of mandibular and maxillary anatomy. The plate also features slots for locking screw fixation. These slots allow for a maximum of 12 fixation points in the bone as well as screw placement variation within the slot to avoid tooth roots. The OmniMax locking screws are 2.0mm in diameter and vary in length from 7mm to 11mm. The screw head also features a low-profile design to minimize irritation and palpability.
The document provides information about the Biomet Microfixation OmniMax MMF System, specifically for its 510(k) submission, K202969. It describes the device, its indications for use, and a comparison to a predicate device. However, it does not contain information about acceptance criteria or a study proving the device meets acceptance criteria in the way typically associated with diagnostic AI/ML device submissions (e.g., performance metrics like sensitivity, specificity, AUC).
Instead, the non-clinical performance data section focuses on validation testing for the cleaning process and biocompatibility assessment as the primary acceptance criteria for this specific submission, which seems to be an update or modification rather than a completely new device that requires extensive clinical performance evaluation.
Here's a breakdown of the information available based on your request, highlighting what is present and what is explicitly stated as not necessary or not evaluated:
Acceptance Criteria and Device Performance
Acceptance Criteria | Reported Device Performance |
---|---|
Cleaning Validation: Meets standards outlined in FDA guidance document "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling." | "Testing passed all Cleaning validation meets the standards outlined in FDA guidance document acceptance criteria." |
Biocompatibility Assessment: Adherence to predicate device standards per ISO 10993-1, following manufacturing process flow updates and review of contact materials. | "Process monitoring results and review of contact materials has passed acceptance criteria established by the predicate device per ISO 10993-1." |
Study Details (Based on the provided document)
