Tribio® DP Wedge is a bone void filler consisting of 60% hydroxyapatite (HA) and 40% beta-tri-calcium phosphate (TCP). These materials have been the topic of extensive clinical studies for several decades. The device provides a scaffold around which new bone can grow. A series of surface reactions on the particles results in the formation of a calcium phosphate layer that is substantially equivalent in composition and structure to the hydroxyapatite found in bone mineral. After implantation, the device resorbs and is later replaced by natural bone.
A bioabsorbable, implantable device made of a synthetic material(s) intended to replace bone lost through trauma, surgery, or pathological conditions (e.g., osteoporosis); it is not dedicated to dental applications and does not include an antimicrobial agent(s). It may be made of ceramics (e.g., tricalcium phosphate or hydroxyapatite), bioactive glasses/minerals/metals (e.g., strontium), or bioabsorbable polymers. Also referred to as a graft, matrix, or void filler, it typically provides an osteoconductive scaffold that promotes bone growth, and is used to fill cystic defects, repair fractures, and/or extend autogenous bone grafts. It may have adhesive properties.
