摘　　要：暂时冠、桥是永久性固定修复体完成粘固前的一种过渡性修复。作者给１００例适应做固定修复的病人做了过渡性暂时冠、桥，共计１３２个修复体，其中单冠１２０个，固定桥１２个，对促进永久固定修复的成功和取得病人信任起了很大帮助。文中介绍了暂时冠桥制作的常用几种方法。并对暂时冠、桥的作用及设计要求进行了讨论。The preparation of teeth for fixed prosthetic restorations needs the temporary restoration for various reasons.Once the enamel has been removed, a vital tooth of the sensitive dentin is exposed to the oral environment. If left unprotected teeth, the patient would experience a significant amount of sensitivity to the various stimulations to which the tooth is exposed. In addition, exposed dentin is much more susceptible to caries than enamel is. The prepared tooth is also lacking contact mesiodistally as well as occlusally with its counterparts in the dentition. It is not uncommon for th prepared tooth to drift mesially or distally or to extrued in an occlusal direction. This movement would, of course, cause problems in seating the final restoration. Temporization also allows for the testing of both the esthetic and functional design of the final restoration.This paper showed some fabricating methods for temporary crown and bridge and discussed the effect on the temporary crown and bridge and its needs for design.
