Bi-Ostetic Foam Putty is a sterile bone graft composed of purified fibrillar Type I collagen and Bi-Ostetic (60% hydroxyapatite - 40% tricalcium phosphate) resorbable granules. This device is safe and has excellent biocompatibility. After it is implanted, the graft resorbs and is later replaced by natural bone. Bi-Ostetic Foam Putty is indicated for use in bony voids or gaps that are not intrinsic to the stability of the bony structure. The product should be gently packed into bony voids or gaps of the skeletal system (i.e., the extremities, posterolateral spine and pelvis). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. The product provides a bone void filler that resorbs and is replaced by the growth of new bone during the healing process. In weight bearing situations, the graft is to be used in conjunction with internal or external fixation devices. The fracture defect treated should not exceed 30 ml.
A bioabsorbable, implantable device made of synthetic materials (e.g., ceramics such as tricalcium phosphate or hydroxyapatite) combined with animal-derived bone growth factors (e.g., bovine collagen) intended to replace bone lost through trauma, surgery, or pathological conditions (e.g., osteoporosis); it is not dedicated to dental applications. 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 is typically provided as cancellous blocks, chips, or granules of varying sizes, or mouldable materials.
