摘　　要：目的比较3种记录颌位关系方法对全口义齿再修复患者不同时期咀嚼效率的影响。方法随机选择20名全口义齿再修复患者采取自身对照的方法,每位患者分别采用直接咬合法、哥特式弓描记法、哥特式弓联合面弓转移颌位关系法制作3副全口义齿,并比较不同方法下制作的义齿在患者即刻佩戴义齿时、佩戴义齿3个月后的咀嚼效率的差异。结果患者即刻佩戴义齿时咀嚼效率测定结果显示,使用哥特式弓联合面弓转移颌位关系法制作全口义齿的患者咀嚼效率明显高于使用其他2种方法制作全口义齿的患者(P<0.05),而使用直接咬合法与哥特式弓描记法制作全口义齿的患者咀嚼效率没有差异;佩戴义齿3个月后,3组患者的咀嚼效率无明显差异。结论使用哥特式弓联合面弓转移颌位关系法可为患者提供更可靠的颌位记录方法,可以提高患者的即刻咀嚼效率,提高患者的满意度和医生的工作效率。Objective The masticatory efficiency of patients in different periods was evaluated by three methods of recording jaw relations in complete denture replacement. Methods This randomized self-controlled trial included 20 patients, who were subjected to complete denture replacement. Direct interocclusal records, Gothic arch tracing, and combination of Gothic arch tracing and face bow transfer were used. These methods were carried out to evaluate masticatory efficiency after immediately wearing the denture（before occlusal grinding） and three months after occlusal grinding. Results For patients immediately wearing dentures, the masticatory efficiency by combination of Gothic arch tracing and face bow transfer was significantly higher than the other two methods, and the difference was statistically significant（P〈0.05）. Direct interocclusal records and Gothic arch tracing methods exhibited no statistically significant difference. The masticatory efficiency three months after occlusal grinding by the three methods showed no significant difference. Conclusion The combination of Gothic arch and face bow transfer improved the patient＇s masticatory efficiency immediately, the efficiency of doctors, and the satisfaction of patients.
