(牙合)架(articulator)又称咬合器,是口腔矫形临床常用的一种器械。用以固定患者的上下颌模型,可保持上下牙弓的正中(牙合)位,或上下颌弓的正中关系和垂直距离,以便在口外进行排牙和调磨咬合。复杂的(牙合)架因能较精确地摹拟下颌的功能运动,故可用来研究咬合与下颌运动的关系,或颞下颌关节疾病的诊断和治疗等。一、(牙合)架的分类验架的种类很多,分类方法也较多,本文仅提出两种分类法:①按其摹拟下颌运动
(Occlusal) articulator (articulator), also known as articulator, orthodontics is a commonly used clinical equipment. The maxillary and mandibular models, which are used to secure the patient, maintain the median occlusion of the upper and lower dental arch, or the median and vertical distance of the upper and lower jaw to allow for tooth extraction and buffing outside the mouth. Complex (occlusal) frame because it can more accurately simulate the functional movement of the mandible, it can be used to study occlusal and mandibular movement relationship, or the diagnosis and treatment of temporomandibular joint disease. First, classification of (occlusal) frame A large number of classification frame, classification methods are more, this article presents only two categories: ① according to imitate the jaw movement
