摘要
重度牙周炎造成牙周软硬组织的严重破坏,患牙拔除后会进一步导致牙槽骨不可逆吸收和软组织塌陷缺如,若拔牙同期行位点保存术可减少牙周炎患牙剩余牙槽骨的过度吸收,有效保存牙龈组织,为后期种植修复创造良好的牙周基础条件,从而获得令人满意的种植修复的功能和美学效果。文章就牙周炎患牙拔除后位点保存的意义,牙周炎对位点保存的影响,牙周炎患牙拔除后位点保存技术操作要点、种植时机及效果评价等做一综述。
Severe periodontitis causes serious damage to the periodontal tissue,and tooth extraction due to periodontitis leads to further irreversible bone resorption and poor soft tissue contour. Immediate alveolar ridge preservation after tooth extraction can reduce excessive bone resorption,preserve soft tissue effectively,and create favorable periodontal condition for implant prosthesis,so as to obtain satisfactory functional and esthetic outcome. The objective of this review is to discuss the significance of alveolar ridge preservation after tooth extraction due to periodontitis,the influence of periodontitis on alveolar ridge preservation,the operation points of this technique,the timing for implantation,and the evaluation of treatment outcome.
