正中关系的研究现状

Research progress on centric relation

正中关系(CR)在近一个世纪以来一直是一个极具争议性的话题。虽然它涉及口腔修复学、正畸学及学等多个学科,是一种非常重要的颌位关系,但是,对于它的明确定义、获取方式及与颞下颌关节紊乱病(TMD)之间的关系等问题仍缺乏统一的意见。了解CR确切含义、正确地获取方法对于有效开展临床工作有着重要的意义。本文对关于CR的定义、获取方式及与TMD之间的关系等方面作一综述。

Centric relation （CR） has been a controversial subject for over a century. Although it is an important factor of occlusion, and closely related to prosthodontics, orthodontics and gnathology, scientists have never come to consensus on a clear definition, a correct way of determination or a clear relationship with temporomandibular disorder（TMD） of CR. The purpose of this paper is to review the controversial subjects above.
