金属、烤瓷修复体修复牙列重度磨耗后的咀嚼效能

The masticatory efficiency of the metals porcelain prostheses restoration for severe tooth wear

目的:运用金属或烤瓷修复技术修复牙列重度磨耗伴牙列缺损的临床效果。方法:先采用过渡性牙合垫(牙合垫式义齿)恢复患者的垂直距离,正中关系。改善TMD症状,再改用金属、烤瓷修复技术重建咬合,观察患者的临床感受,咀嚼效率。结果:45例患者,修复后主观感觉良好,咀嚼效率提高,TMD症状改善或消失。结论:金属、烤瓷冠修复牙列重度磨耗、牙列缺损患者,修复后美观、舒适、咀嚼效率与正常牙列相似。

Objective：To explore a new method and it＇s clinical efficiency of porcelain technique on severe tooth wear and dentition defect. Methods ： The transitional occlusal pad restored the vertical dimension and centric relation, decreased TMD syrnptoms. The porcelain technique was used to reconstruct the occlusal relationship, their prognoses and patients＇ satisfactory were recorded. Results ： 45 patients suffered from serious dental abrasion, whose clinical symptoms got much better and masticatory efficiency improved significantly. Conclusion ： Porcelain is an aesthetic and comfortable technique to improve patients＇ masticatory efficiency significantly which is similar to real tooth.
