Intended Use

OssGuide is recommended for: - Simultaneous use of GBR-membrane (OssGuide) and implants; - Augmentation around implants placed in immediate extraction sockets; - Augmentation around implants placed in delayed extraction sockets; - Localized ridge augmentation for later implantation; - Alveolar ridge reconstruction for prosthetic treatment; - Aid regeneration of bone defects after root resection, cystectomy, removal of retained teeth; - Guided bone regeneration in dehiscence defects

Device Story

OssGuide is a sterile, single-use, bioresorbable collagen membrane derived from porcine pericardium. Used in dental surgery by clinicians to facilitate guided bone regeneration (GBR). The membrane acts as an occlusive physical barrier, placed between the mucoperiosteal flap and the bone defect to prevent epithelial and connective tissue ingrowth. It provides a scaffold for bone regeneration and is resorbed by host tissue within 24 weeks. Clinicians trim the membrane to fit the defect, placing it dry or hydrated, and secure it with sutures or tacks. The device benefits patients by promoting bone healing in dental defects and around implants.

Clinical Evidence

No human clinical data. Evidence consists of in vitro characterization (physicochemical, tensile strength, suture pull-out) and an in vivo animal study in beagle dogs (n=20). The animal study compared OssGuide to Bio-Gide/Bio-Oss, demonstrating sufficient GBR effect for alveolar bone regeneration with complete biodegradation by 24 weeks.

Technological Characteristics

Bioresorbable membrane made of purified porcine pericardium collagen. Porous, fibrous, bilayer structure. Dimensions: 15x20mm to 30x40mm. Sterilized via gamma irradiation. Complies with ASTM F2212 (physicochemical), ISO 10993 (biocompatibility), ISO 11607-2 (packaging), and ISO 22442 (animal tissue control).

Indications for Use

Indicated for patients requiring guided bone regeneration (GBR) in dental procedures, including implant site augmentation (immediate/delayed extraction sockets), localized ridge augmentation, alveolar ridge reconstruction, and bone defect regeneration following root resection, cystectomy, or tooth removal.

Regulatory Classification

manufacturing process. The OssGuide has a porous and fibrous microstructure that prevents the ingrowth of fibrous tissue into the bone defect.

OssGuide is packed by a packaging material composed of a transparent side and is easy to use by open system of easy peel type. It is easy to check the OssGuide, because one side of packaging is transparent closed by double packing system in order to protect OssGuide from microbial formation and moisture penetration. Then this packaged OssGuide is sterilized by gamma irradiation. The packaging contains the OssGuide and one Tyvek material template.

The surgical procedure consists of placing of an occlusive physical barrier between the connective tissue and the bone defect to prevent the migration of the epithelial and connective tissue cells into the defect. The periodontal defect or bone defect is exposed by a mucoperosteal flap and basic surgical procedures (e.g. curettage) are performed. The clinician should perform thorough debridement and efficient planing of the defect. Space-making material such as autologous bone or bone substitute may be used to fill the defect. OssGuide can be placed either dry or hydrated. OssGuide can be trimmed to the size and shape of the defect in a dry or wet state using scissors. A piece of sterile Tyvek may be used as a template for membrane sizing and trimming. OssGuide should overlap the walls of the defect by at least 2 mm to allow complete bone contact and to prevent gingival connective tissue invasion below the material. The membrane may be secured in place with sutures, tacks, or by means of sufficient contact with the mucoperiosteal flap to avoid displacement and micro motion during healing. To facilitate proper healing, ensure that there is tension-free primary closure of the soft tissue flap covering the membrane.

OssGuide a bioresorbable scaffold that is eventually resorbed by host tissue. OssGuide is substantially resorbed within 24 weeks after implantation.

The OssGuide is available to the United Sates market in 5 sizes as shown below. They are supplied sterile and intended for single use only.

#### 08. Non-Clinical Test Conclusion

The determination of substantial equivalence was based on an assessment of non-clinical performance data obtained from in vitro characterization studies, an in vivo animal study, biocompatibility testing.

In vitro product characterization testing was performed to demonstrate substantial equivalence of the subject device to its predicate device in biochemical, mechanical properties. The test results demonstrated that the proposed device complies with the following standards:

- · Physicochemical Characterization per ASTM F2212
- Tensile strength testing
- · Suture pull-out strength testing

Validation of packaging, shelf life, transport and sterilization are performed as following:

- · Validation of Primary and Secondary barrier packaging per ISO 11607-2
- Validation of shelf life per ASTM F1980 using age accelerated and real-time aged samples
- · Validation of transport packaging per ASTM D4169
- · Validation of sterilization parameters per ISO 11137

Biocompatibility of the subject device was evaluated in accordance with ISO 10993-1 as followings:

- · Cytotoxicity per ISO 10993-5
- · Sensitization per ISO 10993-10
- · Irritation per ISO 10093-10
- · Subchronic Toxicity per ISO 10993-11
- · Genotoxicity per ISO 10993-3
- · Implantation per ISO 10993-6
- · Material mediated pyrogenicity per USP

Results indicate that the device's biocompatibility profile is acceptable.

The pyrogenicity of OssGuide was tested in vivo using the Rabbit Pyrogen Test as per USP <151>, and the test article was judged as nonpyrogenicity sample testing plan, the endotoxin (LAL) testing will be conducted on every batch of OssGuide products.

The manufacturing control of animal tissue components is performed as following:

- · Controls on sourcing, collection, and handling per ISO 22442-2
- · Viral Inactivation per ISO 22442-3

Animal study was conducted in the alveolar bone defect of beagle dogs to evaluate the in vivo performance and degradation of the OssGuide, supporting substantial equivalence. The study was conducted on 20 animals followed for 4, 8, 12 and 24 weeks. When comparing OssGuide with the predicate device, Bio-Gide with Bio-Oss bone graft material as a positive control, it showed sufficient GBR effect for the alveolar bone regeneration on the alveolar bone defect of beagle dogs. OssGuide maintained their contour until 8 weeks, lost most of its integrity after 12 weeks, and disappeared by biodegradation at 24 weeks.
