摘　　要：目的研究电子面弓辅助固定修复义齿制作对恢复后牙咬合功能的作用。方法本研究选取单侧2个牙位以上的末端咬合游离的固定修复患者16例,共39颗基牙。比较采用传统技术与数字化口内扫描、电子面弓、虚拟[牙合]架CAD/CAM技术制作固定义齿的修复效果差异。并通过口内咬合纸印迹法、调[牙合]时间和T-Scan Ⅲ数字化咬合分析仪,比较两组修复体的咬合功能。结果(1)两种方法制作的修复体在咬合面早接触点、调[牙合]时间上均有明显统计学差异(P<0.01);(2)两组修复体调[牙合]后,两侧后牙咬合均匀,均未发现明显早接触点。结论采用电子面弓辅助制作的固定修复体可以更加精确地恢复患者咬合功能,减少临床调[牙合]时间,有利于降低医疗成本,从而为精准地恢复后牙固定修复体的咬合功能提供理论和数据参考。Objective To study the effect of restoration on posterior occlusal function using fixed partial denture assisted by mandibular movement analyzer.Methods In this study,16 cases with 39 abutments were selected with unilateral terminal occlusal dissociation at more than 2 dental positions.Effects of fixed posterior partial denture were compared between the traditional technology and digital intraoral scanning&mandibular movement analyzer&virtual articulator system&CAD/CAM technology.The occlusal functions of the two groups were compared by articulating paper imprinting,occlusal adjustment time and T-Scan Ⅲ digital occlusal analyzer.Results①There were significant differences in the early contact point and occlusal adjustment time of the occlusal surface between the two groups(P<0.01).②After the adjustment of the two groups of prostheses,both posterior teeth occluded evenly,and no obvious early contact points were found.Conclusion The fixed prosthesis made with the aid of mandibular movement analyzer can more accurately restore the occlusal function of patients.Using mandibular movement analyzer reduces occlusal adjustment time,and helps reduce the medical cost.It provides theoretical and data reference for accurately restoring the occlusal function of fixed posterior dental prosthesis.
