摘要
目的 :探讨铸造桩核烤瓷全冠在后牙牙体缺损修复中的价值。方法 :选择后牙残根、残冠的 16 4颗牙 ,在修复前行完善根管治疗术 ,再采用铸造桩核烤瓷冠的方法修复缺损。通过 3～ 2 4个月的复查结果进行临床效果评价。结果 :该修复体固位力强 ,边缘密合性好且耐磨 ,经过修复后 2年复查 ,有效率达 95 .12 %。结论 :铸造桩核烤瓷全冠是一种效果良好的后牙残根、残冠的修复方式。
Objective To investigate the effect of cast post-core porcelain fused to metal crown on the restoration of residual root and crown of molars.Methods One hundred and sixty-four residual roots and crowns of molars were treated with root canal therapy and restored by cast core porcelain fused to metal crown. The restoration effect was assessed at the 3rd, 6th , 12th, and 24th month.Results The strength of dental prosthesis retention, marginal fitness,and strength of crowns were satisfactory. The effective rate reached 95.12% during the 2 year follow-up.Conclusion The cast post-core porcelain fused to metal crown is a better method in treating the residual root and crown of molars.
