摘　　要：目的比较CAD/CAM氧化锆桩核与玻璃纤维桩树脂核在上颌前牙区修复患者中的应用效果。方法将104例上颌前牙区修复术患者分为2组。对照组(n=52)应用CAD/CAM氧化锆桩核进行修复,研究组(n=52)应用玻璃纤维桩树脂核修复。比较2组患者修复成功率、术后1年内咀嚼功能优良率、抗折裂强度、修复牙牙龈出血指数。结果研究组修复成功率为90. 38%,显著高于对照组75. 00%(P <0. 05)。研究组患者术后1年内咀嚼功能优良率为96. 15%,显著高于对照组82. 69%(P <0. 05)。治疗后,2组的抗折裂强度指数水平均显著高于治疗前,且研究组显著高于对照组(P <0. 05)。治疗后,2组的修复牙牙龈出血指数水平均显著低于治疗前,且研究组显著低于对照组(P <0. 05)。结论相比于CAD/CAM氧化锆桩核,玻璃纤维桩树脂核在上颌前牙区修复患者中的修复成功率更高,患者咀嚼功能优良率更高,抗折裂强度指数水平及修复牙牙龈出血指数水平均更好。Objective To compare the effect of CAD/CAM zirconia post core and fiberglass post and resin core in treatment of patients with restoration of maxillary anterior teeth.Methods A total of 104 patients with restoration of maxillary anterior teeth were divided into two groups,with 52 cases in each group.Control group was treated with CAD/CAM zirconia post and core,while study group was treated with fiberglass post and resin core.The success rate of restoration,the excellent rate of masticatory function,the intensity of fracture resistance and the index of gingival bleeding were compared between the two groups.Results The success rate of restoration in the study group was90.38%,which was significantly higher than 75.00%in the control group(P<0.05).The excellent rate of masticatory function within one year after operation in the study group was 96.15%,which was significantly higher than 82.69%in the control group(P<0.05).After treatment,the intensity of fracture resistance was significantly higher than that before treatment in both groups,and the study group was significantly higher than the control group(P<0.05).After treatment,the index of gingival bleeding was significantly lower than that before treatment in both groups,and the study group was significantly lower than the control group(P<0.05).Conclusion Compared with the CAD/CAM zirconia post core,the fiberglass post and resin core has a higher success rate of restoration,a higher excellent rate of masticatory function,and better intensity of fracture resistance and index of gingival bleeding.
