Collagen Dental Membrane - Conformable PP is a white, nonfriable, resorbable, single layered, conformable collagen membrane matrix manufactured from purified porcine peritoneum. Collagen Dental Membrane - Conformable PP is sterilized by gamma irradiation and is supplied sterile, non-pyrogenic and for single use only.
The collagen dental membrane has a thickness of approximately 0.1 to 0.8 mm and is available in the following sizes 12 x 25 mm. 15 x 20 mm, 25 x 25 mm, 20 x 30 mm, and 30 x 40 mm.
The provided document describes a 510(k) premarket notification for a medical device called "Collagen Dental Membrane - Conformable PP". The purpose of this notification is to demonstrate substantial equivalence to legally marketed predicate devices, not typically to prove device performance against specific acceptance criteria in a clinical setting.
Therefore, the document does not contain information on acceptance criteria in the sense of predefined numerical thresholds for clinical performance metrics, nor does it describe a study specifically designed to establish such performance. Instead, it relies on demonstrating equivalence through non-clinical (bench and animal) testing and the existing clinical history of its predicate devices.
However, I can extract the information on the non-clinical tests performed. Please note that "acceptance criteria" here refers to the expected outcome of these non-clinical tests (e.g., non-cytotoxic, non-mutagenic), rather than clinical performance metrics.
Here is the information based on the document:
1. A table of acceptance criteria and the reported device performance:
| Test | Acceptance Criteria (Expected Outcome) | Reported Device Performance (Results) |
|---|---|---|
| Biocompatibility Testing | ||
| Cytotoxicity | Non-cytotoxic | Non-cytotoxic; No evidence of causing any cell lysis or toxicity. |
| Sensitization | No sensitization | No evidence of causing delayed dermal contact sensitization in the guinea pig. The test article was not considered a sensitizer in the guinea pig test. |
| Intracutaneous Reactivity | No significant erythema or edema | Under the conditions of the study, there was no erythema or edema from the extract injected intracutaneously into rabbits. The test article extract met the requirements of the test since the difference between the mean score of the test extract and the corresponding control was passing. |
| Acute Systemic Toxicity | No mortality or systemic toxicity | No mortality or evidence of systemic toxicity. |
| Genotoxicity (Bacterial Reverse Mutation) | Non-mutagenic | Non-mutagenic to Salmonella typhimurium and to Escherichia coli strain WP2uvra. |
| Genotoxicity (Mouse Lymphoma Assay) | Non-mutagenic | None of the test article treatments induced substantial increases in the number of revertant colonies. Based on the criteria and conditions of the study protocol, the test article is considered non-mutagenic. |
| Pyrogenicity | Non-pyrogenic | Non-pyrogenic |
| Muscle Implantation | Non-irritant (or comparable to control) | The macroscopic reaction was not significant compared with the sponsor provided control article (bovine tendon collagen membrane) and not significant as compared to the negative control article (HDPE). Microscopically, the test article was classified as a nonirritant as compared to the sponsor provided control article and as a moderate irritant as compared to the negative control article. |
| Subchronic Toxicity | Minimum/no adverse tissue reaction | Minimum tissue reaction up to 24 weeks of implantation and no adverse tissue reaction to the host. |

In particular, the Collagen Dental Membrane-Conformable PP and its predicates are similar with respect to intended use, material (porcine peritoneum), form, sizes, thickness, physical integrity, permeability and conformability.
Nonclinical Tests Submitted
The substantial equivalence of Collagen Dental Membrane-Conformable PP and its predicates was demonstrated based on in vitro characterization studies, biocompatibility studies, in vivo animal studies, and clinical history of the predicate devices.
In vitro product characterization testing was performed to demonstrate substantial equivalence of the subject device to its predicate devices. A series of bench tests were conducted which included an evaluation of physical properties such as membrane thickness, conformability, suture strength, and an evaluation of physicochemical properties such as product permeability and hydrothermal transition temperature.
A series of in vitro and in vivo biocompatibility testing was performed to assess safety of the Collagen Dental Membrane-Conformable PP as an implantable material. The device passed all applicable FDA Blue Book Memorandum G95-1and ISO 10993-1 testing for the biological evaluation of medical devices.

| Test | Test Method/Model | Results |
|---|---|---|
| Mouse LymphomaAssay, ISO 10993-3:2003 | None of the test article treatments inducedsubstantial increases in the number of revertantcolonies. Based on the criteria and conditions ofthe study protocol, the test article is considerednon-mutagenic. | |
| Pyrogenicity | Rabbit Pyrogen study-USP <151> | Non-pyrogenic |
| MuscleImplantation | Muscle ImplantationStudy in Rabbits, 2Weeks, ISO 10993-6 | The macroscopic reaction was not significantcompared with the sponsor provided controlarticle (bovine tendon collagen membrane) andnot significant as compared to the negativecontrol article (HDPE). Microscopically, the testarticle was classified as a nonirritant ascompared to the sponsor provided control articleand as a moderate irritant as compared to thenegative control article. |
| SubchronicToxicity | Subcutaneousimplantation study in rat. | Minimum tissue reaction up to 24 weeks ofimplantation and no adverse tissue reaction tothe host. |
In addition to the in vitro characterization tests, animal studies using a rabbit intraoral model, as well as a rat subcutaneous model were conducted to evaluate the in vivo stability and local tissue response to the subject device as compared to its predicate device (BioGide®).
Viral inactivation studies were performed to ensure the viral safety of the product.
Clinical Test Submitted
Given the similarities between Collagen Dental Membrane - Conformable PP and the predicate devices, it was determined that a clinical study would not be necessary to demonstrate substantial equivalence.
7. Conclusion of Non-clinical Studies
The results of the in vitro product characterization and biocompatibility testing, as well as the animal study show that Collagen Dental Membrane-Conformable PP is safe and substantially equivalent to the identified predicate devices.
§ 872.3930 Bone grafting material.
(a)
Identification. Bone grafting material is a material such as hydroxyapatite, tricalcium phosphate, polylactic and polyglycolic acids, or collagen, that is intended to fill, augment, or reconstruct periodontal or bony defects of the oral and maxillofacial region.(b)
Classification. (1) Class II (special controls) for bone grafting materials that do not contain a drug that is a therapeutic biologic. The special control is FDA's “Class II Special Controls Guidance Document: Dental Bone Grafting Material Devices.” (See § 872.1(e) for the availability of this guidance document.)(2) Class III (premarket approval) for bone grafting materials that contain a drug that is a therapeutic biologic. Bone grafting materials that contain a drug that is a therapeutic biologic, such as biological response modifiers, require premarket approval.
(c)
Date premarket approval application (PMA) or notice of product development protocol (PDP) is required. Devices described in paragraph (b)(2) of this section shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.
