摘要: 目的:比较使用下颌运动描记仪、蜡牙合记录及硅橡胶咬合记录测量青年人群中个别正常牙合前伸髁道斜度、侧方髁道斜度的一致性,为临床应用提供理论依据。方法:从本学院高年级本科生中选取32例个别正常牙合,使用Zebris下颌运动描记仪(JMA)、牙合蜡以及咬合记录硅橡胶分别测量受试者的前伸髁道斜度和侧方髁道斜度。结果:下颌运动描记仪测量结果的一致性好于蜡牙合记录及硅橡胶咬合记录,其测量结果分别与蜡牙合记录及硅橡胶咬合记录比较,前伸、侧方髁道斜度均有统计学差异(P<0.05);蜡牙合记录与硅橡胶咬合记录比较,前伸、侧方髁道斜度均无统计学差异(P>0.05)。结论:使用Zebris下颌运动描记仪(JMA)获取前伸、侧方髁道斜度一致性好,灵敏度高且操作便捷,有良好的临床推广价值。

Abstract: Objective: To compare the consistence of measurement of sagittal condylar inclination and transversal condylar inclination of individual normal occlusion in young people with mandibular motion recording device,wax record and silicone rubber occlusal record. Methods: Thirty-two individual normal occlusion from senior students of our college were selected. Zebris mandibular motion recording device (JMA), wax and occlusal recording silicone rubber were used to measure the sagittal condylar inclination and transversal condylar inclination, respectively. Results: The consistence of mandibular motion recording device was better than wax record and silicone rubber occlusal record. There were statistically significant differences in sagittal condylar inclination and transversal condylar inclination between Zebris and wax record (P<0.05) and between Zerbis and silicone rubber occlusal record (P<0.05), however, no significant difference between wax record and silicone rubber occlusal record (P>0.05). Conclusion: Zebris mandibular motion recording device (JMA) has good consistence,high sensitivity and convenience, so it has good clinical promotion value.
