位点保存技术的现状与未来

Current status and future of site preservation techniques

牙槽骨吸收是拔牙后的常见结果,常造成后期种植植入时骨量不足,损害修复后的美学效果。牙周位点保存技术就是在拔牙即刻或者拔牙后所采取的减少牙槽嵴及软组织吸收或增加拔牙窝骨形成的干预措施。应用骨或骨替代材料填充拔牙窝来减少牙槽骨吸收是牙周位点保存技术的最常用方法。该文对位点保存技术的现状、不同骨填充材料的性能进行综述。

Alveolar bone resorption is common outcome after tooth extraction, often resulting in bone deficiency and aesthetic problem in implant and repair. Periodontal sites preservation technology is taken to reduce alveolar bone and soft tissue absorption, or increase bone formation after the tooth extraction. Filling of autogenous bone graft or bone substitute material is the most commonly used method of periodontal sites preservation technology. In the article, the preservation technology status and the properties of different bone filling material were reviewed.
