【摘要】 目的:前瞻性研究短冠磨牙3种修复方式的临床效果，为短冠磨牙修复方式的选择提供依据。方法:对68颗根管治疗后的短冠磨牙分别进行二硅酸锂增强玻璃陶瓷高嵌体(A组，36颗)、纤维分体桩氧化锆高嵌体(B组，17颗)、铸造纯钛分体桩金属高嵌体(C组，15颗)修复，3年后对修复体进行临床评价。结果:A组、B组、C组的修复成功率分别是88.9%,94.1%和80.0%,修复体生存率分别是88.9%、100.0%和93.3%,基牙生存率分别是100.0%、100.0%和93.3%,三组比较差异均无统计学意义(P>0.05)。结论:3种方式修复根管治疗后短冠磨牙均能获得良好的临床效果，可满足不层次短冠磨牙患者的修复需求。更多还原

【Abstract】 Objective: To prospective study the clinical efficacy of three restoration methods for short crown molars. Methods: After root canal treatment, 68 short crown molars were repaired with lithium disilicate reinforced glass ceramic onlays(group A, n=36), fiber split post zirconia onlays(group B, n=17), and cast pure titanium split post metal onlays(group C, n=15). The clinical evaluation was performed 3 years later. Results: In group A, group B, and group C, the success rate of restoration was 88.9%, 94.1%, and 80.0%, and the survival rate of prostheses was 88.9%, 100.0%, and 93.3%, respectively, and the survival rate of abutments was 100.0%, 100.0%, and 93.3%, respectively, with no statistical significance(P>0.05). Conclusion: The three methods can achieve good clinical effect after root canal treatment of short crown molars, which can meet the repair needs of patients with short crown molars of different levels.更多还原
