PURcrystals™ BioCeramic Nanocrystals are a mixture with a nominal composition of 60% hydroxyapatite and 40% beta-tri-calcium phosphate. These materials have been the topic of extensive clinical studies for a several decades. PURcrystals™ is safe and has excellent biocompatibility. After it is implanted, the implant resorbs and is later replaced by natural bone. PURcrystals™ is a natural choice for sparing patients the trauma of autograft harvesting. It also provides a safe alternative to human or animal cadaver bone that completely eliminates the potential for disease transmission.
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.
