牙列重度磨耗附着体咬合重建修复临床效果分析

目的探讨牙列重度磨耗伴游离端缺损用Snap附着体咬合重建修复临床效果。方法对照组38例行牙台垫式可摘义齿修复，观察组38例行Snap附着体修复。随访0．5-3．0年，从主观感受、口腔检查和X线检查分析修复效果。结果面容恢复均满意。对照组7例不满意美观，8例固位差，7例咀嚼效果差，基牙有龋坏、松动和脱落。观察组1例固位差，基牙无龋坏，松动度无明显变化；基牙牙周及牙槽骨无变化，组间比较差异有统计学意义（P〈0．05）。结论牙列重度磨耗伴双侧游离端缺损用Snap附着体咬合重建修复效果优于抬垫式可摘局部义齿。

Clinical effect of attachment in patients with etensive tooth wear during occlusal rehabilitation

Objective To evaluate the clinical effects of occlusal rehabititon with snap attachment in patients of extensive tooth wear with dentition defect.Methods The control group had 38 subjects for occlusal rehabilitation with jaw pad-type removable dentures and the observation group had 38 subjects for occlusal rehabilitation with snap attachment.Results The subjects of two groups were all satisfied with their facial recovery.In the control group,7 subjects were not satisfied with the appearance of their dentures,and 8 subjects were not satisfied with the retention of the dentures,also 7 subjects were not satisfied with the low ability of masticatory and the abutment teeth were decayed,loose or lost.In the observation group,1 subject was not satisfied with the retention of the denture,and the abutment tooth did not decay,also the movability did not change significantly,and the periodontal tissue and the alveolar bone had no change.The differences of two groups were statistically significant(P < 0.05).Conclusion Snap attachment is better than the jaw pad-type removable denture in the occlusal rehabilitation for patients with extensive tooth wear and extensive dentition defect in double side.
