摘　　要：目的探讨玻璃纤维桩氧化锆全瓷冠修复治疗后磨牙牙体缺损的临床效果。方法选取2019年10月至2020年3月抚州市第一人民医院口腔科收治的79例后磨牙牙体缺损患者(168颗缺损牙体)为研究对象,按患者自行选择修复方法分为对照组(39例患者,81颗牙体)和观察组(40例患者,87颗牙体)。对照组采用铸造桩加钴铬烤瓷冠修复,观察组实施玻璃纤维桩氧化锆全瓷冠修复,两组患者均随访6个月,比较两组的修复成功率、咀嚼功能及修复效果。结果观察组患者修复成功率为88.89%,对照组患者修复成功率为95.40%,两组比较差异无统计学意义(P>0.05)。观察组患侧与健侧的咀嚼效率比较,差异无统计学意义(P>0.05);而观察组患侧的咀嚼效率高于对照组,差异有统计学意义(P<0.05)。观察组患者牙齿的边缘密合度、颜色匹配度、牙龈健康情况、修复体完整性、表面磨耗程度均优于对照组,差异有统计学意义(P<0.05)。结论玻璃纤维桩氧化锆全瓷冠修复治疗后磨牙牙体缺损的临床疗效显著,对患者咀嚼能力影响小,且修复效果佳,值得临床推广。Objective To investigate the clinical effect of glass fiber post and zirconia all-ceramic crowns in the treatment of molar defects.Methods A total of 79 cases of posterior molar tooth defects(168 tooth defects)admitted to the Department of Stomatology,Fuzhou First People′s Hospital from October 2019 to March 2020 were selected as the research objects.According to the repair methods selected by the patients,they were divided into a control group(39 patients,81 teeth)and an observation group(40 patients,87 teeth).The control group was repaired with cast post and cobalt-chromium porcelain crown,and the observation group was repaired with glass fiber post and zirconia all-ceramic crown.Both groups of patients were followed up for 6 months to compare the repair success rate,chewing function and repair effect of the two groups.Results The success rate of repair was 88.89%in the observation group and 95.40%in the control group,and there was no statistical significance between the two groups(P>0.05).There was no significant difference between the mastication efficiency of the affected side of the observation group and the healthy side(P>0.05),the mastication efficiency of the affected side of the observation group was higher than that of the control group,and the difference was statistically significant(P<0.05).The marginal tightness,color matching,gum health,restoration integrity,and surface wear of the observation group were better than those of the control group,and the differences were statistically significant(P<0.05).Conclusion The clinical effect of glass fiber post zirconia all-ceramic crown repairing the molar tooth defect after treatment is significant,with little impact on the patient′s masticatory ability,and the repair effect is good,which is worthy of clinical promotion.
