是咀嚼系统功能的枢纽,口腔修复治疗除了满足美观和功能要求,还应确保通过修复体传导到机体的负荷有利于咀嚼系统健康。由于支持方式的差别,不同类型修复体对于关系的要求有所不同。关系设计制作应该参照个体的生理性,尽量准确复制有关的静态和动态因素,控制误差,使修复体与个体的型达到协调。  is the hub of masticatory system functions. In addition to meeting aesthetic requirements and functional requirements, oral rehabilitation should also ensure that the load transmitted to the body through the prosthesis is beneficial to the health of the chewing system. Due to differences in support methods, different types of prostheses have different requirements for relations.  relationship design and production should be based on individual physiological , as far as possible accurate copy of the static and dynamic factors, control error, so that prosthesis and individual  type to achieve coordination.
