摘　　要：目的:评价上下牙列重度磨损的咬合重建固定修复的临床效果。方法:采用金合金烤瓷冠、桥和铸造金合金冠、桥为12例上下牙列重度磨损、正常咬合关系丧失的患者进行咬合重建修复,分别于修复前、最终修复后1、3、6个月进行咀嚼效能的检测;记录修复前后垂直距离进行统计分析;检查基牙的健康状况以及义齿使用情况。结果:冠桥修复前后咀嚼效能差异有统计学意义(F=8.241,P<0.01);修复前后垂直距离差异有统计学意义(T=13.415,P<0.001);修复2年内患者对义齿的固位效果、舒适度与美观性较为满意。结论:应用金合金烤瓷冠和铸造金合金冠进行咬合重建修复的临床效果满意,垂直距离增高,咀嚼效能提高。Objective：To evaluate the clinical effects on occlusal reconstruction using cast gold-alloy crowns and porcelin crowns fused to gold-alloy metal. Methods ：Twelve patients with abnormal occlusion were treated with occlusal reconstruction using east gold-alloy crowns and porcelin crowns fused to gold-alloy metal. The vertical dimensions before and after treatment were tested. The masticatory efficiency before and lmonth,3 months and 6 months after treatment were tested.Results：The differences of the mastieatory efficiency between the stages before and after treatment were significant.The difference of the vertical dimension before and after treatment was significant. Conclusion：The results showed good clinical effects in increasing masticatory efficiency.
