EquiMatrix™ is a sterile, natural, non-antigenic, porous bone mineral matrix produced by the removal of organic compounds from equine bone. Due to its natural structure EquiMatrix™ is physically and chemically comparable to the mineralized matrix of human bone. The anorganic bone matrix of EquiMatrix™ has a macro and microporous structure similar to human bone. The formation and in-growth of new bone at the implantation site of EquiMatrix™ is favored due to its trabecular architecture, interconnecting macro and micro pores, and its natural consistency. It is supplied as cancellous (spongiosa) or cortical granules in a single use container, packaged in a secondary thermoform blister, and sterilized by v-irradiation.
The provided document is a 510(k) summary for the EquiMatrix™ Natural Bone Mineral Matrix. It describes the device, its intended use, and argues for its substantial equivalence to a predicate device, Bio-Oss®.
Here's an analysis of the provided text in relation to your request about acceptance criteria and a study proving device conformance:
The document does not describe an AI/ML device. It is a regulatory submission for a medical device (bone grafting material) that is a physical product, not a software algorithm. Therefore, many of your specific questions related to AI/ML device performance (like sample sizes for test sets, data provenance, ground truth establishment by experts, MRMC studies, standalone performance, training sets) are not applicable to this document.
However, I can extract information related to the device's "performance" and "acceptance criteria" as understood in the context of this biological material.
1. Table of Acceptance Criteria and Reported Device Performance
For this type of device, "acceptance criteria" are typically demonstrating equivalence to a recognized standard or predicate device in terms of material properties, biocompatibility, and intended biological function (e.g., bone formation). The document argues for substantial equivalence to Bio-Oss®.
| Item | Acceptance Criteria (based on equivalence to predicate/standards) | Reported Device Performance (EquiMatrix™) |
|---|---|---|
| Intended Use | Used as an adjunctive therapy in restoring bony defects (matching predicate) | Used as an adjunctive therapy in restoring bony defects. Applications include augmentation/reconstruction of alveolar ridge, filling various bone defects (periodontal, post-resection/cystectomy, extraction sockets), maxillary sinus floor elevation, and use with GTR/GBR products. |
| Target Population | Human oral, periodontal (matching predicate) | Human oral, periodontal |
| Dosage Form | Granules contained in single use container (matching predicate) | Granules contained in single use container |
| Granule Sizes | 0.25 mm to 1.0 mm or 1.0 mm to 2.0 mm granules (matching predicate) | 0.2 mm to 1.0 mm or 1.0 mm to 2.0 mm granules (Slight difference in lower bound of smaller size, but deemed equivalent) |
| Material | Anorganic naturally derived osteoconductive hydroxyapatite bone mineral (matching predicate) | Anorganic naturally derived osteoconductive hydroxyapatite bone mineral (from equine bone) |
| Source Bone | Biological source for anorganic bone mineral. Not explicitly an "acceptance criteria" beyond general material characteristics from xenograft, but the difference from predicate (equine vs. bovine) is a key point of comparison. | Equine bone |
| Physical Morphology | Trabecular, interconnecting macro and micro pores (matching predicate) | Trabecular, interconnecting macro and micro pores (similar to human bone) |
| Biocompatibility | Biocompatibility as per ISO 10993 and FDA's "Class II Special Controls Guidance Document: Dental Bone Grafting Devices" (matching predicate's inherent biocompatibility) | Biocompatible, demonstrated by: Genotoxicity, Intracutaneous reactivity, Maximization and sensitization, Pyrogen, Acute systemic injection, Cytotoxicity, Implantation, Preclinical safety and efficacy testing, Clinical case series. Confirmed product safety. |
| Performance (Bone Formation) | Osteoconductive and supports bone formation (matching predicate's known function) | Supports bone formation; "formation and in-growth of new bone at the implantation site of EquiMatrix™ is favored due to its trabecular architecture, interconnecting macro and micro pores, and its natural consistency." Animal studies showed both products (EquiMatrix™ and Bio-Oss®) grew new bone and resorbed at similar rates. Clinical case series resulted in "defect healing and formation of new bone of sufficient quality to obtain dental implant placement." |
| Chemical Composition | Similar to predicate's chemical composition (based on chemical analyses, XRD, FT-IR, and ICP analysis) | Similar to Bio-Oss® based on chemical analyses, XRD, FT-IR, and ICP analysis. Organic material removed, product specifications established to limit protein content. |
| Sterilization Process | Sterile by Gamma irradiation (matching predicate) | Sterile by Gamma irradiation (achieving SAL 1 x 10⁻⁶) |
| Chemical Safety | Biocompatible (matching predicate) | Biocompatible |
| Pyrogen Free | Yes (matching predicate) | Yes |
| Shelf Life | Acceptable shelf-life demonstrated. Predicate's shelf life is "determined by manufacturer," so the criteria is to have a valid, determined shelf life. | 3 years |
Since this is a non-AI/ML device, the following points are not applicable or cannot be extracted from the document:
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Not applicable as this is not an AI/ML device. The document mentions "several animal studies" and a "clinical case series" but does not provide sample sizes or data provenance details for these studies.
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 as this is not an AI/ML device. Ground truth, in a clinical sense for this device, would be histological analysis of bone growth, clinical outcomes (implant placement success), and assessment of defect healing, typically done by attending clinicians or pathologists, but not "experts establishing ground truth for a test set" in the AI/ML context.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not applicable as this is not an AI/ML 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 as this is not an AI/ML device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable as this is not an AI/ML device.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)
- For the biological performance of the device (bone formation), the document implies:
- Histological assessment: Implied by "formation and in-growth of new bone," likely from the animal studies.
- Clinical outcomes data: Mention of "defect healing and formation of new bone of sufficient quality to obtain dental implant placement" from the "clinical case series" suggests clinical assessment of surgical sites and successful subsequent treatment.
- Physico-chemical characterization: Ground truth for material properties (composition, morphology) is established through analytical techniques like XRD, FT-IR, ICP analysis.
8. The sample size for the training set
- Not applicable as this is not an AI/ML device.
9. How the ground truth for the training set was established
- Not applicable as this is not an AI/ML device.

Device Description
EquiMatrix™ is a sterile, natural, non-antigenic, porous bone mineral matrix produced by the removal of organic compounds from equine bone. Due to its natural structure EquiMatrix™ is physically and chemically comparable to the mineralized matrix of human bone. The anorganic bone matrix of EquiMatrix™ has a macro and microporous structure similar to human bone. The formation and in-growth of new bone at the implantation site of EquiMatrix™ is favored due to its trabecular architecture, interconnecting macro and micro pores, and its natural consistency. It is supplied as cancellous (spongiosa) or cortical granules in a single use container, packaged in a secondary thermoform blister, and sterilized by v-irradiation.
Technological Aspects of Particulate Bone Grafting
Particulate bone grafts (cancellous and cortical) are widely used in dentistry for the treatment of periodontal bone defects, prevention of alveolar resorption following tooth extraction, and to augment deficient and atrophic sites prior to implant placement.
Although autogenous tissue has been traditionally regarded as the gold standard for bone regeneration, it has the disadvantage of limited availability, increased patient morbidity, and irregular resorptive patterns. Therefore, other sources of graft material including allogenic, alloplastic, and xenogenic particles have been developed and studied as an osteoconductive matrix for new bone formation.
Xenoarafts of bovine origin have proven to be especially useful for guided bone regeneration in stabilizing the blot clot, promoting revascularization and maintaining space during wound healing. There is also an inherent advantage in these xenografts for sinus augmentation and in the aesthetic zone as a foundation for implant and dental reconstruction due to the slower resorption rate.

K///816
Equimatrix is a particulate natural bone mineral derived from horses which is proposed as an alternative xenograff material for use where dental bone grafting is required for treatment of periodontal defects and implant site development.
Basis for Substantial Equivalence
EquiMatrix™ and Bio-Oss® have a similar physical and chemical structure. Both are porous, biocompatible bone grafts that facilitate the formation and mineralization of new bone by the osteoblast. The primary difference between the two products is the source bone: EquiMatrix™ is manufactured from equine (horse) bones, while Bio-Oss® is manufactured from bovine (cows) source material.
The following table summarizes the basis for the Sponsor's substantial equivalence determination:
