Methodology Ten subjects （6 women,4 men; mean age 25.4 years） participated in the study. The mandibular move-ment,sagittal condylar inclination angle,and transversal condylar inclination angle of each subject were recorded with the CADIAX？ using the two clutches,respectively. The characteristics of the tracings of the protrusion,opening,and mediotrusion were analyzed with the t-test statistics at α = 0.05 level. The Kappa values were calculated for an assessment of the congruence of the tracings. Results The results showed that the contour,direction,and dimension of the tracings in the two clutches were approxi-mately same,but the tracings determined by the functional occlusal clutch were more regular and congruent. In the group segment recorded with the tray clutch,opening/ closing paths of one subject showed crossed and time curves of three subjects appeared peak-like changes of velocity,but none were statistically different （P0.05）. Conclusion The research suggests that the functional occlusal clutch should be preferred in the evaluation of the mandibular function,as the tracings with the tray clutch are more likely to produce false positive results.展开更多
目的:分析固定-活动义齿在牙齿重度磨耗伴缺失治疗中的应用效果。方法:回顾性分析2020年2月-2021年10月在笔者医院行口腔修复治疗的88例牙齿重度磨耗伴缺失患者的临床资料,按治疗方式的不同分为对照组(n=43,活动义齿修复)和研究组(n=45...目的:分析固定-活动义齿在牙齿重度磨耗伴缺失治疗中的应用效果。方法:回顾性分析2020年2月-2021年10月在笔者医院行口腔修复治疗的88例牙齿重度磨耗伴缺失患者的临床资料,按治疗方式的不同分为对照组(n=43,活动义齿修复)和研究组(n=45,固定-活动义齿修复)。修复后半年判定两组修复效果,并比较两组患者修复前及修复后半年咀嚼效能、颞下颌关节(Temporomandibularjoint,TMJ)功能、生活质量及修复满意度。结果:研究组修复效果(95.56%)明显高于对照组(81.40%)(P<0.05);修复后两组咬合力、咀嚼效率和修复前相比均明显增高(P<0.05),且研究组高于对照组(P<0.05);修复后两组Helkimo临床功能障碍指数、TMJ功能指数(Fricton指数)中的TMJ紊乱指数评分、口腔健康影响程度量表14(Oral health impact scale 14,OHIP-14)评分和修复前相比均明显降低(P<0.05),且研究组低于对照组(P<0.05);研究组患者修复满意度评分高于对照组(P<0.05)。结论:应用固定-活动义齿对牙齿重度磨耗伴缺失患者进行修复的效果较佳,可明显改善患者咀嚼效能和TMJ功能,有效提高其生活质量,并能够提升患者满意度。展开更多
