研究目的:

在重度牙周炎患牙和牙列的牙周再生中通过保留肉芽组织的治疗方式,探索利用牙周内窥镜辅助下的有效清创,在不翻瓣的情况下获得牙周再生的有利空间和血供,联合植骨材料或生长因子的应用,并采用激光辅助杀菌和生物学刺激调节牙周局部微环境,龈下喷砂获得维护期的有效菌斑控制,本课题的重点在于评估上述方案对重度牙周炎患牙和牙列保存治疗的可行性,为重度牙周炎患牙和牙列的保存性治疗提供新的思路。  

Objectives of Study:

In the treatment of periodontal regeneration of teeth and dentition with severe periodontitis, effective debridement assisted by periodontal endoscopy was explored to obtain favorable space and blood supply for periodontal regeneration without flap turnover, combined with the application of bone graft materials or growth factors, and laser assisted sterilization and biological stimulation were used to regulate the local periodontal microenvironment, subgingival sandblasting In order to achieve effective plaque control in the maintenance period, the focus of this project is to evaluate the feasibility of the above scheme for the preservation treatment of teeth and dentition with severe periodontitis, and to provide a new idea for the preservation treatment of teeth and dentition with severe periodontitis.
