摘　　要：目的探讨两种不同的修复方式用于根管治疗后后牙楔状缺损修复治疗的效果。方法选取2017年1月至6月石家庄市第一医院口腔科收治的60例根管治疗后后牙楔状缺损修复患者,根据患者主观选择修复方式分为A组和B组,各30例。A组采用纤维桩+复合树脂+氧化锆烤瓷冠修复,B组采用金属桩核+金属烤瓷冠修复。对比两组修复成功率,修复前后的牙龈菌斑指数、牙龈指数、牙周探诊深度及修复后的效果。结果修复后6个月复查,两组患者修复成功率比较差异无统计学意义(100. 00%vs 93. 33%,P>0. 05)。修复后1年复查,A组患者的修复成功率高于B组,差异有统计学意义(96. 67%vs 73. 33%,P<0. 05)。修复后1年,A组患者的菌斑指数、牙龈指数、牙周探诊深度均低于B组,差异有统计学意义(P<0. 05,P<0. 01)。修复后1年,A组患者修复体的边缘密合性高于B组(P<0. 05)。两组修复体表面光滑、颜色匹配、固定良好率差异无统计学意义(P>0. 05)。结论采用纤维桩+复合树脂+氧化锆烤瓷冠修复管治疗后后牙楔状缺损的效果优于金属桩核+金属烤瓷冠修复。Objective To compare the effects of two different repair methods for root canal therapy on the posterior wedgeshaped defects. Methods Sixty patients with posterior wedge-shaped defect repair after root canal treatment from January 2017 to June 2017 were selected and divided into group A and group B(n = 30,each) according to the patient’ s supervisor. Fiber post,composite resin and zirconia porcelain crown repair were used in group A,and metal post core and metal porcelain crown repair were used in group B. The repair success rate,gingival plaque index before and after repair,gingival index,periodontal probing depth and the effect after repair were compared between two groups. Results After 6 months of repair,there was no significant difference in success rate of repair between two groups(100. 00% vs 93. 33%,P >0. 05). After one year of repair,the success rate in group A was statistically higher than that in group B(96. 67% vs73. 33%,P< 0. 05);the plaque index,gingival index and periodontal probing depth were significantly lower than those in group B(P< 0. 05,P< 0. 01);the edge adhesion in patient’s prosthesis in group A was higher than that in group B(P<0. 05). There were no statistically differences in the surface smoothness,color matching and fixation rate between two groups(P >0. 05). Conclusion The effect of fiber post,composite resin and zirconia porcelain crown repair is better than metal post core and metal porcelain crown repair on the posterior teeth wedge defect after root canal therapy.
