Centric relation (CR) was used in the complete dentures for edentulous jaws firstly. Then, CR was gradually applied in the clinical diagnosis and treatment of dentate jaws. Regarding the application of CR in dentate jaws, there are many doubts about its rationality. For instance, should CR be the core of diagnosis and treatment of temporomandibular disorders? Should CR be used as the jaw position of establishing occlusion in occlusal reconstruction? Should CR serve as the target jaw position in orthodontic treatment? Meanwhile, varieties of CR clinical applications are objective. According to the existing evidence, this paper summarizes the applicable conditions of several main clinical situations with little controversy. We preliminarily put forward the decision tree for the clinical application of CR, which can be used as a reference in clinical practice.
正中关系（centric relation，CR）最初应用于无牙颌全口义齿，随后逐渐应用于有牙颌的临床诊断和治疗。关于 CR 在有牙颌中的应用，存在诸多争议，例如 CR 是否应作为颞下颌关节紊乱病诊断和治疗的核心？CR 是否应作为咬合重建中建立咬合的颌位？CR 是否应作为正畸治疗的目标颌位？同时，CR 的各种临床应用也是客观存在的。基于现有证据，本文对几种争议较小的主要临床情况的适应证进行了总结，初步提出了 CR 临床应用的决策树，可为临床实践提供参考。
