摘　　要：目的探讨不同程度前牙牙体缺损玻璃纤维桩核修复的临床疗效。比较前牙重度牙体缺损运用冠延长术和未运用冠延长术后玻璃纤维桩修复的临床效果。方法临床选择182例前牙缺损患者的共295颗患牙,按牙体缺损程度分3类:Ⅰ类、Ⅱ类和Ⅲ类,按缺损程度所有患牙分为A、B、C、D、E五组,A组为Ⅰ类牙体缺损62颗,B组为Ⅱ类牙体缺损77颗,C组为Ⅲ类牙体缺损并保留2 mm以上牙本质肩领的患牙59颗,D组为Ⅲ类牙体缺损48颗,E组为Ⅲ类牙体缺损49颗,A、B、C、D四组均采用玻璃纤维桩核修复,E组采用牙冠延长术牙体颈部获得至少2 mm大小的牙本质肩领后采用玻璃纤维桩核修复。结果 A、B、C、D、E各组治疗成功率分别为100%、100%、96.6%、85.4%、97.9%,其中A、B、C、E四组之间两两比较无显著性差异(P>0.05),D、E两组之间比较有显著性差异(P<0.05)。结论前牙牙体缺损颈部留有至少2 mm大小的牙本质肩领,玻璃纤维桩核修复能达到较好的效果,牙冠延长术后玻璃纤维桩核能有效修复重度前牙缺损。Objective To study the clinical effects of glass-fiber post on anterior teeth with varying ferrule heights and configurations.To compare the clinical effects of glass-fiber post following surgical crown lengthening or not on severe anterior teeth defect.Methods 295 anterior teeth with varying ferrule heights were divided into Ⅰ、Ⅱ、Ⅲdegree teeth defects.All teeth were divided into five groups：A、B、C、D、E.Group A：62 teeth with Ⅰdegree defect;Group B：77 teeth with Ⅱdegree defect;Group C：59 teeth with Ⅲdegree defect;Group D：48 teeth with Ⅲ degree defect;Group E：49 teeth withⅢ degree defect;The groups of A、B、C、D were restored with glass-fiber post;The teeth of group E gained ferrule no less than 2mm following surgical crown lengthening and were restored with glass-fiber post.Results The success rates of group A、B、C、D、E were 100%、100%、96.6%、85.4%、97.9%respectively.The difference between A、B;A、C;A、E;B、C;B、E;C、E was not significant（P0.05）.The difference between D、E was significant（P0.05）.Conclusions The clinical effect of glass-fiber post was satisfying in the restoration of anterior teeth defect,with ferrule no less than 2mm.Glass-fiber post crown restoration following surgical crown lengthening could effectively restore severe anterior teeth defect.
