THE Graft Bone Substitute is a natural and porous bone mineral matrix available in cancellous granules packaged in vial or syringe. It is produced by removal of all organic components from porcine bone. The composition of THE Graft Bone Substitute meets the requirements of ASTM F1581 Standard Specification for Composition of Anorganic Bone for Surgical Implants. Due to its natural structure of macro and microscopic structures, the anorganic bone mineral of THE Graft Bone Substitute is physically and chemically comparable to the mineralized matrix of human bone.

Further to the right, the words "Dental Biologics Solution" are stacked vertically in a smaller, purple font. 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 favored 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. THE Graft Bone Substitute is not intended to be marketed or sold with multiple components and/or accessories. | Type | Model No. | Particle Size<br>(mm) | Capacity | Packaging | |------------------------|-----------|-----------------------|----------|--------------------------| | Cancellous<br>Granules | TG-AS25 | 0.25 ~ 1.00 mm | 0.25 cc | Syringe +<br>Tyvek Pouch | | | TG-AS05 | | 0.50 cc | | | | TG-AS10 | | 1.00 cc | | | Cancellous<br>Granules | TG-BS25 | 1.00 ~ 2.00 mm | 0.25 cc | Syringe +<br>Tyvek Pouch | | | TG-BS05 | | 0.50 cc | | | | TG-BS10 | | 1.00 cc | | ### List of product models seeking clearance in this submission: Previous submission information: Previous submission: THE Graft Bone Substitute(K173188) This submission is to change syringe package material from the predicate.
