正中关系获取方式及评价体系的研究现状

正中关系(Centric Relation,CR)是上下颌关系的唯一稳定参考位,是咬合重建时重要的参考颌位。它涉及到口腔修复学、牙合学及正畸学等多个学科。目前,正中关系是近一个世纪以来牙科学领域最受争议的话题,对于正中关系的定义、获取方式及其评价标准等问题,学术界尚不能达成共识。因此,了解CR的确切概念、正确地获取方法及如何评价其精确程度对于口腔临床工作有着重要的意义。本文就正中关系的概念、获取方式及其评价体系等方面作一综述。

Recording Methods and Appraisal Systems of Centric Relation.

Centric relation (CR) is the only stable position between maxilla and mandible. It is also a vital jaw relation during the reconstruction of a proper occlusion.CR is an important factor to occlusion, which is also closely related to prosthodontics, gnathology and orthodontics. CR has been a controversial subject for over a century. There is no consensus on the clear definition, the correct way to determine, and the appraisal method, which is very important for the clinical work. This review aims to review the controversial subjects mentioned above.
