本文主要就用于修复牙周骨缺损的生物陶瓷之选择,动物实验和临床研究以及有关的生物陶瓷特性加以综述。一、问题的提出修复牙周病引起的骨缺损一直是牙周病治疗的棘手问题。用自体骨或异体骨移植诱导骨形成以修复骨缺损,是临床上常用的有一定疗效的方法之一。然而,用自体骨移植,口内取骨量有限,要取得足够的自体骨,常需自其它部位进行手术取骨。这既增加患者痛苦,也不易为患者所接受。术后可能发生牙根吸收和粘连。异体骨移植克服了自体骨移植的缺点,但异体骨有抗原性,使用前需经一定的处理,贮藏需一定的条 This review focuses on the selection of bioceramics used in the repair of periodontal bone defects, animal experiments and clinical studies, and the bioceramic properties involved. First, the problem proposed Repair of periodontal bone defects caused by the treatment of periodontal disease has been a thorny issue. Bone autologous or allogeneic bone graft induced bone formation to repair bone defects, is clinically used to have a certain effect of one of the methods. However, with autologous bone grafts, limited intraoral osseointegration, to obtain adequate autologous bone, often require surgery from other parts of the bone. This not only increases patient suffering but also is not easily accepted by the patient. Root resorption and adhesions may occur after surgery. Allogeneic bone graft to overcome the shortcomings of autologous bone graft, but allogenic bone antigenicity, to be treated before use, the need to store a certain section
