摘　　要：【目的】探讨纤维桩、树脂核结合全瓷冠修复体的临床应用及其优、劣势。【方法】161例患者的190颗残根、残冠经完善的根管治疗后,采用制作玻璃纤维桩、双固化树脂核恢复基牙外形并行氧化锆全瓷冠修复。【结果】纤维桩组95颗修复体经24个月的临床随访观察,2颗桩核折断(其中12的桩核在9个月折断,34桩核于19个月时折断),1颗桩核松动(7个月),2颗边缘可探及微小缝隙,所有修复体颜色匹配度均完好,修复效果满意,成功率为96.9%。与金属桩组比较(成功率为84.2%),差异具有统计学意义(P<0.05)。【结论】玻璃纤维桩、双固化复合树脂、氧化锆全瓷冠是目前修复牙体大面积缺损的临床较理想的修复体。[Objective] To study the fiber post and resin core combined with clinical application of all-ceramic crown restorations and their advantages and disadvantages.[Methods]In 161 patients 190 residual roots and crowns,after perfect root-pipe treatment, the production of glass fiber post, dual curing resin core recovery of abutment teeth shape parallel zirconia all-ceramic crown restoration. [Results]Fiber post 95 restorations after 24 months of clinical follow-up observation, 2 broken post and core （12, post and core in the nine month break, 34 nuclear in the 19 months to break）, 1 teeth post-core loosening （7 months）, 2 edge detection and tiny gap, all restorations color matching degree are in good condition, satisfactory repair, the success rate for 96.9%. And the metal pile group （84.2% success rate）, the difference was statistically significant （P 0.05）. [Conclusion]Glass fiber post, dual curing composite resin, zirconia all-ceramic crown is the repair of big dentinal body defect the more ideal clinical restoration.
