Intended Use

THE Graft Bone Substitute is intended for use as a bone grafting material in dental surgery such as: - Filling of extraction sockets to enhance preservation of the alveolar ridge - Elevation of maxillary sinus floor

Device Story

THE Graft Bone Substitute is a resorbable, porcine-derived cancellous bone graft material composed of hydroxyapatite. It functions as a natural, porous mineral matrix with interconnected macro and micro pores that support trabecular architecture. Used in dental surgery, the material is packed into bony sites (extraction sockets or maxillary sinus floor) by a clinician. It acts as a scaffold, gradually resorbing and being replaced by new bone during the healing process. The device is supplied sterile in vials or syringes for single-use.

Clinical Evidence

Evidence includes non-clinical bench testing (ASTM F1581 compliance), comprehensive biocompatibility testing (ISO 10993 series: cytotoxicity, sensitization, reactivity, toxicity, genotoxicity, implantation), and sterilization/viral inactivation validation. In-vivo dog model testing and clinical data were provided to assess performance as an implantable material; all acceptance criteria were met.

Technological Characteristics

Material: Porcine cancellous bone (hydroxyapatite). Structure: Porous, irregular-shaped particles with interconnected macro/micro pores. Dimensions: 0.2–0.355 mm, 0.25–1.0 mm, or 1.0–2.0 mm. Sterilization: Gamma irradiation (ISO 11137, SAL 10^-6). Compliance: ASTM F1581. Packaging: Glass vial or syringe in Tyvek pouch.

Indications for Use

Indicated for dental surgery patients requiring alveolar ridge preservation via extraction socket filling or maxillary sinus floor elevation.

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

*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.

DEVICE DESCRIPTION THE Graft Bone Substitute is a resorbable bone graft material made of porcine cancellous bone consisting of Hydroxyapatite(HA). THE Graft Bone Substitute is a natural and porous bone mineral matrix available in cancellous granules packaged in a vial or syringe. It is manufactured by removal of most organic components from porcine bone. The composition of THE Graft Bone Substitute meets the requirements of ASTM F1581 Standard Specification for Composition of Anorqanic Bone for Surgical Implants. Due to its natural structure of macro and microscopic structures, the anorqanic bone mineral of THE Graft Bone Substitute is physically and chemically comparable to the mineralized matrix of human bone. When packed into a bony site, THE Graft Bone Substitute is gradually resorbed and replaced with new bone during the healing process. The formation and ingrowth of new bone at the implantation site of THE Graft Bone Substitute is due to its trabecular architecture, interconnecting macro and micro pores and its natural consistency. THE Graft Bone Substitute is supplied sterile, non-pyrogenic, and for single use only. ### VI. INDICATIONS FOR USE THE Graft Bone Substitute is intended for use as a bone grafting material in dental surgery such as: - Filling of extraction sockets to enhance preservation of the alveolar ridge । - Grafting of maxillary sinus floor । ### VII. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE THE Graft Bone Substitute is substantially equivalent to the predicate device: Porcine Anorganic Bone Mineral K140714, in which the basic features, raw materials, material composition, intended uses, technological characteristics and performance characteristics are similar. THE Graft Bone Substitute and the predicate device have similar Indications for Use. Both devices are intended for the same population and sterilized by gamma irradiation. The devices are made of biocompatible calcium phosphate bone mineral derived from porcine cancellous tissue adequate for bone formation. The devices feature trabecular-like characteristics, including interconnected macro and micro pores. {5}------------------------------------------------ Image /page/5/Picture/0 description: The image contains the logo for Purgo Dental Biologics Solution.
