Overview of the possibility of bone replacement for the purpose of pre-prosthetic preparation of the patient

Introduction. The loss of the jaw bone, especially in area alveolar process, can significantly complicate procedure prosthetic rehabilitation patients. reason for bones are physiological and pathological processes. Materials. Bone replacements widely used reconstruction bone defects. optimal characteristics these materials biocompatibility, bioinertness, biofunctionality a special canalicular intercanalicular system. Alloplastic inorganic, synthetic, biocompatible bioactive with osteoinductive potential. Hydroxyapatite is preparation based on calcium phosphate. It has high low immunogenicity good osteoconductive characteristics. Poor properties poor mechanical resistance as well degree resorption. Therefore, research chemically modified hydroxyapatites containing different ions was started. Conclusion. Calcium be replaced by various metal like cobalt, aluminum, nickel, manganese, chromium, copper liquid medium.
