摘　　要：目的:分析利用前伸下颌法辅助直接咬合法核对全口义齿水平颌位关系的临床疗效。方法:对50例无牙颌患者病例采用直接咬合法转移水平颌位关系,分别采用前伸下颌法(实验组n=28)和传统方法(对照组n=22)对已转移的水平颌位关系进行核对。在完成修复后采用吸光度法检测2组患者全口义齿的咀嚼效率,及义齿使用3个月后问卷调查患者的总体满意度,进行统计学分析。结果:全口义齿初戴调牙合后,覆牙合、覆盖的变化量实验组均小于对照组,差异具有统计学意义(P<0.05)。两组咀嚼效率测量值实验组大于对照组,差异具有统计学意义(P<0.05)。义齿使用3个月后满意度调查结果,美观程度、固位功能及语音功能两组差异无统计学意义(P>0.05),而咀嚼功能及舒适性实验组得分大于对照组,差异具有统计学意义(P<0.05)。结论:利用前伸下颌法辅助直接咬合法转移并核对全口义齿水平颌位关系更符合生理功能,为全口义齿修复提供更可靠的颌位记录核对方法,一定程度上提高全口义齿咀嚼功能及舒适度。Objective：To observe the clinical effects of forward mandibular method auxiliary record horizontal jaw positions of complete dentures .Methods：Fifty patients were selected and subjected to complete denture .The methods of hori-zontal jaw relationship recording were used for the direct interocclusal records , including experimental group （ n=28 ） using the method of mandibular protrusion ,and the control group （ n=22 ） .The mastication efficiency of horizontal jaw position in different groups were examined by the method of chewing peanut .A questionaire on the satisfaction was used in this study in order to analyse the valitity of the complete dentures , and the results were statistically analyzed .Results：After occlusion grinding ,there were statistically significant differences in the chang overbite , the overjet and the mastication efficiency be-tween the two groups .Also there were statistically significant differences in the patient satisfaction in mastication and comfor between two groups .Conclusion：Use a forward mandibular method to check the horizontal jaw positions of complete dentures with physiological functions ,and provide more reliable recording of checking jaw position for the patients of complete denture that effectively improve denture masticatory function and comfort .
