Beta-bsm Injectable Bone Substitute Material is a synthetic, biocompatible bone graft substitute material. At the time of use, the powder component is combined with a specified volume of mixing solution and mixed to form a paste. Mixing is facilitated by a syringe-to-syringe mixing system. The resulting paste can be administered to the treatment site under direct visualization using the syringe or manual application. The material can be shaped into a desired form in-situ prior to implantation. After the paste is applied to the treatment site, it hardens at body temperature and converts to an apatitic calcium phosphate material. The end product, poorly crystalline hydroxyapatite (PCHA), is of low crystalline order with a similar chemical and crystalline structure to that of natural bone minerals. Beta-bsm Injectable Bone Substitute Material is an osteoconductive material that is resorbed and replaced by natural bone over time.

Gamma-bsm Moldable Bone Substitute Material is a synthetic, biocompatible bone graft substitute material. At the time of use, the powder component is combined with a specified volume of mixing solution and mixed to form a putty. The resulting putty is administered to the treatment site by manual application. The material can be shaped into a desired form in-situ prior to implantation. After the putty is applied to the treatment site, it hardens at body temperature and converts to an apatitic calcium phosphate material. The end product, poorly crystalline hydroxyapatite (PCHA), is of low crystalline order with a similar chemical and crystalline structure to that of natural bone minerals. Gamma-bsm Moldable Bone Substitute Material is an osteoconductive material that is resorbed and replaced by natural bone over time.

EquivaBone is a biocompatible bone graft substitute material consisting of synthetic calcium phosphate, carboxymethyl cellulose (CMC) and human demineralized bone matrix (DBM). It is supplied in a single use kit as sterile powders and hydration solution that are mixed together at the time of use in the operating room to form flowable putty which is implanted manually or can be extruded through a syringe. After implantation the product hardens at body temperature and resorbs and remodels during the healing process. Each lot of DBM contained within EquivaBone is assayed for osteoinductive potential in an athymic nude mouse model. This may or may not be predictive of EquivaBone osteoinductivity in humans.

Here's an analysis of the provided text to extract the acceptance criteria and study information for the Beta-bsm, Gamma-bsm, and EquivaBone devices:

1. Acceptance Criteria and Reported Device Performance

The acceptance criteria for these devices are primarily based on demonstrating substantial equivalence to predicate devices, especially regarding their intended use and technological characteristics. The performance data is assessed against the requirements outlined in the "Class II Special Controls Guidance Document: Dental Bone Grafting Material Devices (dated April 28, 2005)."

The reported device performance, for all three devices (Beta-bsm, Gamma-bsm, and Equivabone), is that they are "safe and effective for its intended use and performs as well as the predicate device."

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

The documents state that non-clinical testing was performed "consistent with Class II Special Controls Guidance Document: Dental Bone Grafting Material Devices (dated April 28, 2005)."

• Sample Size: The specific sample sizes for non-clinical tests (e.g., in-vitro, bench studies, animal studies) are not detailed in the provided summaries. The summaries only state that testing was performed according to the guidance.
• Data Provenance: The document does not specify the country of origin of the data or whether the studies were retrospective or prospective. Given that they are non-clinical studies for device clearance, they would typically involve studies conducted in a controlled lab environment.

For EquivaBone specifically: There's mention of DBM being "assayed for osteoinductive potential in an athymic nude mouse model." This indicates an animal model study was part of the non-clinical testing for this specific characteristic. The sample size for this mouse model is not provided.

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

No information is provided regarding traditional "ground truth" establishment by experts in the context of diagnostic performance or clinical outcomes for these devices.

Since the submission is for a "Special 510(k) Submission - Alternate Hydration Solution" and relies on non-clinical testing and substantial equivalence, the "ground truth" is established by demonstrating that the modified device (with the alternate hydration solution) maintains the same performance characteristics as the predicate device and meets established material and biological safety standards. This is typically assessed by regulatory bodies (like the FDA) and their expert reviewers, rather than external clinical experts establishing a ground truth for a test set in the way one might for an AI diagnostic device.

4. Adjudication Method for the Test Set

Not applicable. This is not a clinical trial involving human subject adjudication of diagnostic findings. The regulatory review process involves evaluation of non-clinical data by regulatory scientists and engineers.

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

No. An MRMC comparative effectiveness study is not mentioned as it is not typically required for this type of device modification (alternate hydration solution) and regulatory pathway (Special 510(k) based on substantial equivalence and non-clinical data). The focus is on demonstrating that the new hydration solution does not negatively impact the established performance and safety of the device.

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

Not applicable. These are inert/resorbable bone graft substitute materials, not AI algorithms or diagnostic devices.

7. Type of Ground Truth Used

The "ground truth" in this context is implicitly "performance equivalence to the predicate device and adherence to recognized material and biological safety standards." This is established through non-clinical testing (e.g., material characterization, biocompatibility testing, mechanical properties, resorbability studies) as outlined by the "Class II Special Controls Guidance Document: Dental Bone Grafting Material Devices."

For EquivaBone, an additional "ground truth" element for osteoinductivity is established via the athymic nude mouse model for each lot of DBM.

8. Sample Size for the Training Set

Not applicable. These are physical medical devices, not AI models that require training sets. The "training" for the device's development would involve R&D and engineering, but not in the AI sense.

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

Not applicable, as there is no "training set" in the context of AI. The development process for these medical devices involves established engineering and scientific principles, quality systems, and regulatory guidelines to ensure safety and effectiveness.
