目的探讨可摘牙合重建对重度牙合磨损伴双侧后牙游离缺失患者的髁状突移位的调位作用。方法根据治疗前及传统可摘义齿和可摘牙合重建义齿戴用后双侧颞颌关节侧位体层摄片上关节间隙线性测量值，对４２侧髁状突位置进行评判分析。结果治疗前髁状突后移位和上移位分别为８５．７％（３６／４２）和５４．８％（２３／４２），可摘义齿戴用和可摘牙合重建治疗后髁状突调整居中心分别为２６．２％（１１／４２）和７８．６％（３３／４２），左右侧关节对称性亦以可摘牙合重建治疗为佳。结论高覆盖可摘牙合重建治疗可达完全调整髁状突移位作用，而可摘义齿修复不能有效地调整髁状突达正常位置
OBJECTIVE: To investigate the role of dislocated reconstructions in the adjustment of mandibular condyle shift in patients with severe occlusal wear and bilateral free tooth loss. Methods According to the linear measurement of the joint space between the preoperative and the traditional removable denture and the removable denture reconstruction denture, the location of 42 lateral condyles was evaluated. Results The posterior condyle displacement and uplift were 85.7% (36/42) and 54.8% (23/42) respectively before treatment, and the removable denture The sudden center of congenital heart disease were 26.2% (11/42) and 78.6% (33/42), respectively. The symmetry of the left and right joints was also treated with removable dental reconstruction. Conclusions High coverage removable denture reconstruction can completely adjust the effect of condylar shift, but the removable denture can not effectively adjust the condylar protrusion to the normal position
