RESUMO
Bone grafts [Alograft. Autograft and synthetic bonegraft] are used to rapaire bone defects. According to several technical and medical problems. synthetic bone grafts [B.G] are perefered to others. Nova Bone is an ABG which in more available in Iran, now .So we conducted this study to evaluate it. 62 Patients with bone defects who needs bone graft during 1 year, under went Nova Bone graft. F/U data we analysed, according to graft failure and calcium formation. 6 patients out of 62 had been failed to form calcium after 20 weeks of F/U .[9.7%]. There were no other Complications [infection and noninfectious]. Using SBG [including Nova Bone] has been advocated recently due to several problems including Allografts and Autografts. Favorable results [90.3% calcium formation] in patients with Nova Bone grafts [alone or in combination with auto and Allograft] Propose the regular use of it for patients need bone grafts
