牙周病骨缺损是临床牙齿松动脱落的主要原因之一。本研究采用与骨组织成份相似的HAC植入牙周骨缺损区。结果证明,羟磷灰石陶瓷(HAC)与牙槽骨、牙根有良好的组织相容性。组织学观察发现,HAC植入后为新生骨组织包绕,结合为HAC-骨质复合体,可长期存留于新形成的骨组织内而不被吸收。研究结果表明HAC具有骨引导能力,是修复牙周骨缺损的良好材料。 Periodontal disease bone defect is one of the main reasons for the clinical loss of teeth. In this study, HACs similar to bone tissue were implanted into the periodontal defects. The results show that hydroxyapatite ceramics (HAC) and alveolar bone, root has good histocompatibility. Histological observation showed that, after implantation of HAC, nascent bone tissue is surrounded and combined with HAC-bone complex, which can be retained in the newly formed bone tissue for a long time without being absorbed. The results show that HAC has osteoconductive ability and is a good material for repair of periodontal defects.
