摘　　要：目的:研究运用下颌运动轨迹描计法记录无牙颌颌位关系。方法:随机选取无牙颌志愿患者8名,制作牙合托并利用JT-3D下颌轨迹描记仪记录患者习惯性开闭口运动轨迹,寻找下颌姿势位点,引导患者运动至该位点矢状位上方2 mm处,咬合记录硅橡胶固定颌位关系,转导至牙合架。重新制作牙合托,戴入患者口腔,采用息止颌间隙法及后牙咬合法验证颌位关系是否正确。结果:8名受试患者运用下颌运动轨迹描计法取得的颌位关系均通过传统颌位记录方法得以论证。结论:下颌运动轨迹描计法记录无牙颌颌位关系可行,较传统颌位关系记录更为直观、便捷。Objective： The objective of this study was to apply mandibular kinesiograph to recording the maxillomandibular relation of edentulous patients. Methods： Eight volunteer edentulous patients were selected randomly,prepared impression and plaster model,fabricated occlusion rim. Then JT-3 D mandibular kinesiograph meter was used to record habitual opening and closing movement and mandibular postural position（ MPP）. The patients were guided to close mouth 2 mm above the MPP on sagittal plane. At the position the maxillomandibular relation was fixed with the occlusal record silicone rubber.Freeway space and posterior teeth occlusion methods were used to verify the relation correctly. Results： The maxillomandibular relation of all the edentulous patients was correct by applying mandibular kinesiograph. Conclusion： Mandibular kinesiograph can be applied to record the maxillomandibular relation of edentulous patients more intuitively and conveniently than traditional methods.
