Inion GTR™ Tack Description The Inion GTR™ Biodegradable Tacks are intended to be used with the biodegradable membrane by fastening the membrane in position. The use of Inion GTR™ Tacks with the biodegradable membrane is indicated for surgical treatment of periodontal defects (e.g. class II furcation defects, intrabony defects and recession type defects), for pre-implant and peri-implant surgery and for covering bone defects and empty sockets. Fig. 1 The plastic dispenser with 4 Tacks, TCK-2013 The Inion GTR™ Biodegradable Tacks are made of degradable copolymers composed of L-Lactide acid, D-lactic acid, and trimethylene carbonate. These polymers degrade in vivo by hydrolysis into alpha-hydroxy acids that are metabolized by the body. The Inion GTR™ Tacks are provided in a plastic dispenser and supplied as sterile, single use products.
