摘　　要：目的:探讨哥特氏弓测定无牙颌正中颌位的准确性。方法:比较30例无牙颌患者分别使用4种方法(lvoclar哥特氏弓、Girrbach哥特氏弓、诱导法恒基托.诱导法蜡基托)测定正中颌位的临床效果。结果:哥特氏弓测定正中颌位的准确性高于另两种方法。lvoclar哥特氏弓结构简单小巧,操作方便,使用主要受(牙合)间距离大小的限制;Girrbach哥特氏弓结构复杂,经久耐用,对技工要求高,使用受(牙合)间距离大小和腭穹隆形态的限制。结论:并非所有患者都能使用口内哥特氏弓确定无牙颌水平方向的正中颌位;在可以使用口内哥特氏弓的病例中,哥特氏弓准确性更高。Objective：To investigate the veracity of Gothic arch transferring centric relation position of edentulous jaws. Methods：The veracity of centric relation position of four methods（Ivoclar Gothic arch, Girrbach Gothic arch, inducement constant base using inducement way, wax base using inducement way） were compared during 30 edentulous patients. Results： The veracity of Gothic arch was higher than that of other two methods. Ivoclar Gothic arch was laconic and cabinet, easy to operate, mainly restricted by maxillomadibular distance. Girrbach Gothic arch was made of complex structure, demand high level of mechanic, mainly restricted by maxillomadibular distance and palatal vault shape, but wear well. Conclusion;Not all of the patients can use intraoral Gothic arch to determine horizontal centric relation position of edentulous jaws. The veracity is higher than routine inducement method if the patient can use Gothic arch.
