Intended Use

Collagen Dental Membrane - Conformable PP is intended for use in oral surgical procedures as a resorbable membrane material for use in: - Simultaneous use of GBR-membrane and implants - Augmentation around implants placed in immediate extraction sockets - Augmentation around implants in delayed extraction sockets - Localized ridge augmentation for later implantation - Alveolar ridge reconstruction for prosthetic treatment - Filling of bone defects after root resection, cystectomy or removal of retained teeth - Guided bone regeneration in dehiscence defects and - Guided tissue regeneration procedures in periodontal defects.

Device Story

Collagen Dental Membrane - Conformable PP is a resorbable, single-layered collagen matrix derived from purified porcine peritoneum; used in oral surgery as a barrier to facilitate guided bone and tissue regeneration. Device acts as a physical scaffold to support healing in defects around implants, extraction sockets, and periodontal sites. Supplied sterile via gamma irradiation for single-use. Clinicians place the membrane over the surgical site to prevent soft tissue ingrowth into bone defects, promoting predictable bone regeneration. Benefits include biocompatibility, conformability to surgical sites, and eventual resorption, eliminating need for secondary removal surgery.

Clinical Evidence

No clinical data. Substantial equivalence established via bench testing and animal studies. Bench testing included membrane thickness, conformability, suture strength, permeability, and hydrothermal transition temperature. Biocompatibility testing (ISO 10993) confirmed non-cytotoxicity, non-sensitization, non-mutagenicity, and non-pyrogenicity. Animal studies (rabbit intraoral, rat subcutaneous) evaluated in vivo stability and local tissue response compared to predicate (BioGide®).

Technological Characteristics

Material: Purified porcine peritoneum. Form: Single-layered, nonfriable, conformable membrane. Thickness: 0.1–0.8 mm. Sterilization: Gamma irradiation. Biocompatibility: ISO 10993 compliant. Physical properties: Permeable, conformable, suture-compatible.

Indications for Use

Indicated for patients undergoing oral surgical procedures requiring a resorbable membrane for guided bone or tissue regeneration, including implant site augmentation, ridge reconstruction, and bone defect filling.

Regulatory Classification

Identification

# 6. Summary/Comparison of Technical Characteristics

Collagen Dental Membrane-Conformable PP and its predicate devices have similar technological characteristics. 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 |
|------------------------------|-----------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Cytotoxicity | Agarose Overlay, ISO<br>10993-5 | Non-cytotoxic; No evidence of causing any cell<br>lysis or toxicity. |
| Sensitization | Guinea Pig<br>Maximization, ISO<br>10993-10 | No evidence of causing delayed dermal contact<br>sensitization in the guinea pig. The test article<br>was not considered a sensitizer in the guinea pig<br>test. |
| Intracutaneous<br>Reactivity | Intracutaneous Study in<br>Rabbits, ISO 10993-10 | Under the conditions of the study, there was no<br>erythema or edema from the extract injected<br>intracutaneously into rabbits. The test article<br>extract met the requirements of the test since the<br>difference between the mean score of the test<br>extract and the corresponding control was<br>passing. |
| Acute Systemic<br>Toxicity | Acute Systemic Toxicity<br>in Mice, ISO 10993-11 | No mortality or evidence of systemic toxicity. |
| Genotoxicity | Bacterial Reverse<br>Mutation Study, ISO<br>10993-3 | Non-mutagenic to Salmonella typhimurium and<br>to Escherichia coli strain WP2uvra. |

| Test | Test Method/Model | Results |
|-----------------------------------------------|------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Mouse Lymphoma<br>Assay, ISO 10993-<br>3:2003 | | None of the test article treatments induced<br>substantial increases in the number of revertant<br>colonies. Based on the criteria and conditions of<br>the study protocol, the test article is considered<br>non-mutagenic. |
| Pyrogenicity | Rabbit Pyrogen study-<br>USP <151> | Non-pyrogenic |
| Muscle<br>Implantation | Muscle Implantation<br>Study in Rabbits, 2<br>Weeks, ISO 10993-6 | The macroscopic reaction was not significant<br>compared with the sponsor provided control<br>article (bovine tendon collagen membrane) and<br>not significant as compared to the negative<br>control article (HDPE). Microscopically, the test<br>article was classified as a nonirritant as<br>compared to the sponsor provided control article<br>and as a moderate irritant as compared to the<br>negative control article. |
| Subchronic<br>Toxicity | Subcutaneous<br>implantation study in rat. | Minimum tissue reaction up to 24 weeks of<br>implantation and no adverse tissue reaction to<br>the 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.
