纤维桩树脂核与金属铸造桩核修复前牙缺损的临床效果比较

目的比较纤维桩树脂核与金属铸造桩核修复前牙缺损的临床效果。方法临床分别选择90颗前牙患者,年龄19～62岁,已经过完善的根管治疗,分别采用纤维桩树脂核与金属铸造桩核材料制作烤瓷桩冠修复,6个月～3年后对修复效果进行临床对比评价。结果经过6个月～3年的随访观察,结合临床检查和X线检查,纤维桩树脂核组90颗患牙修复体良好,无松动,无折裂,烤瓷冠边缘密合。金属铸造桩核组2颗患牙根折,2颗患牙桩核松动脱落,10颗患牙龈缘出现灰色素沉着,其余78颗患牙修复良好。结论使用纤维桩树脂核可以达到满意的修复效果,较金属铸造桩核更适于前牙缺损的修复。

The comparision of the clinical effect of glass fiber post and core & cast metal post and core in the resto-ration of anterior teeth defect

Objective To compare the clinical effect of glass fiber post and core cast metal post and core in the restoration of anterior teeth defect.Methods 90 anterior teeth,age from 19 to 62,under went excellent endodontic treatment,restored with PFM crown by glass fiber post and core metal post and core,after 6 months～3 year.Results During 6 months～3 years clinical observation,with the help of clinical examine,and X-ray,good results were found in aspects of the retention,marginal adaption in the group of 90 cases glass fiber post and core.2 teeth were found root fracture in the group of cast metal post and core.2 post and core were loose.Gingival grey line was found around 10 teeth.The rest 78 teeth restorations functioned well.Conclusion Clinical effect of glass fiber post and core was satisfying,better then cast metal post and core in the restoration of anterior teeth defect.
