牙周炎是由于牙菌斑中的微生物所引起的牙周支持组织的慢性感染性疾病,表现为进行性附着丧失和牙槽骨吸收,最后导致牙齿松动,已经成为我国成年人丧失牙齿的首位原因。牙周炎治疗的重点在于消除炎症的基础上有效修复牙周炎造成的牙槽骨缺损。本研究使用羟基磷灰石生物陶瓷治疗牙周骨下袋,通过与单纯翻瓣术的疗效比较,探索新的骨代用材料在牙周病患者中的应用前景。1资料与方法 Periodontitis is a chronic infectious disease of periodontal support tissues caused by microorganisms in plaque and manifests as progressive attachment loss and alveolar bone resorption that eventually leads to tooth loss and has become the first adult loss tooth in our country the reason. The focus of periodontitis treatment is to eliminate inflammation based on the effective repair of periodontitis caused by alveolar bone defects. In this study, hydroxyapatite bioceramic was used to treat the periodontal osteosarcoid pouch, and its potential application in periodontal disease patients was explored by comparing with the curative effect of simple flap surgery. 1 data and methods
