Intended Use

THE Graft Collagen is recommended for: - Filling of extraction sockets to enhance preservation of the alveolar ridge.

Device Story

THE Graft Collagen is a bone grafting material composed of 85% porcine-derived cancellous bone mineral matrix and 15% porcine tendon-derived Type I collagen. The device acts as a scaffold for new bone formation; collagen provides structural integrity and handling characteristics, allowing the material to be trimmed or molded to fit various defect shapes. Used by dental clinicians in clinical settings for alveolar ridge preservation. The device is supplied sterile via gamma irradiation. Clinical benefit includes facilitating bone augmentation and defect filling. The healthcare provider implants the material into the defect site to support bone regeneration.

Clinical Evidence

No clinical trials were conducted. Evidence consists of bench testing (physicochemical properties, Ca/P ratio, compressive strength), biocompatibility (ISO 10993 series), sterilization validation (ISO 11137, SAL 10^-6), and animal origin controls (ISO 22442). In-vivo performance was evaluated in a beagle mandibular intraoral model comparing the subject device to the primary predicate via histology, histomorphometry, and Micro-CT at 4, 8, 12, 16, and 24 weeks, demonstrating substantial equivalence.

Technological Characteristics

Material: Porcine-derived hydroxyapatite bone mineral and Type I collagen. Form: Block. Sterilization: Gamma irradiation (SAL 10^-6). Biocompatibility: Compliant with ISO 10993. Animal origin controls: ISO 22442-2/3. Non-pyrogenic per USP <85>.

Indications for Use

Indicated for filling of extraction sockets to enhance preservation of the alveolar ridge in patients requiring bone grafting.

Regulatory Classification

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.

Special Controls

The logo is clean and modern, suggesting a focus on scientific and biological solutions for dental care. The subject device is substantially equivalent to the primary predicate device K122894 in indication for use, function, material, design, biocompatibility and sterilization. Differences include the size range, composition of bone mineral and collagen, and animal origin of bone mineral. #### Discussion on the differences - · Size range - The subject and primary predicate devices can be trimmed to fit the defect shapes, so the sizes do not affect usage. - Composition of bone mineral and collagen - The subject device contains 85% The Graft Bone Substitute (K173188) granules and 15% porcine collagen. The primary predicate device contains 90% Bio-Oss® granules and 10% porcine collagen. In both devices, granules serve as a scaffold for new bone and collagen is used to hold the granules. So, composition of collagen does not affect to the intended use. - · Animal origin of bone mineral - Bone mineral of the subject device is derived from porcine and that of the predicate device is derived from bovine. The animal origin is different, but the safety of material was verified through biocompatibility tests and virus inactivation validation. ## 8. Conclusion Based on the information provided, the subject device is substantially equivalent to the primary predicate device.
