下半口无牙颌固定修复的分段式修复设计

The segmented restoration design of implant-supported fixed restoration in edentulous mandible

随着现代口腔种植学的发展,越来越多的无牙颌患者寻求种植固定修复。下半口无牙颌进行种植固定修复时,分段修复设计和整体修复设计如何选择是临床医生十分关心的问题。本文从生理、机械、制作、维护四个方面对分段式设计的相关内容进行论述,总结认为下半口无牙颌固定修复,采取分段式设计更为合理,只有当解剖条件受限,无法满足分段式设计方案时,才考虑植入较少的种植体进行整体式修复。

With the development of modern oralimplantology,more and more edentulous patients seek for implant-supported fixed restoration.In the edentulous mandible,to select the segmented restoration design or the one-piece restoration design is a problem that clinicians are very concerned about.This article discusses the related content of segmented restoration design from four aspects:physiology,mechanism,process and maintenance.It is concluded that in the edentulous mandible the segmented design is more reasonable.Only when the anatomical conditions are limited and the segmented design cannot be satisfied,the one-piece design is considered to be applied.
