摘　　要：目的:探究钴铬合金、银钯合金、二氧化锆和玻璃陶瓷四种不同修复体对前牙缺损患者的近远期治疗效果影响。方法:选取2017年2月-2019年4月来笔者医院就诊的前牙牙体缺损患者152例,采用随机数表法分为四组,分别为钴铬合金组、银钯合金组、二氧化锆组和玻璃陶瓷组,每组38例。各组患者入院完善相关检查后,分别采用钴铬合金、银钯合金、二氧化锆或玻璃陶瓷材料修复缺损牙体,分别对比各组患者修复前、修复后6个月及修复后12个月牙龈指数变化情况;比较各组患者治疗效果并对各组患者进行为期2年随访,评价患者远期疗效;比较各组患者修复前、修复后6个月及修复后12个月龈沟液内天冬氨酸转氨酶(AST)、碱性磷酸酶(ALP)表达水平变化情况。结果:各组患者治疗前牙龈指数比较无明显差别,玻璃陶瓷组和二氧化锆组修复后6个月牙龈指数明显下降,修复后12个月玻璃陶瓷组较其余各组明显降低,结果具有统计学意义(P<0.05);各组患者治疗后疗效显示:玻璃陶瓷组患者远期疗效较好,二氧化锆组较钯银合金、钴铬合金组远期疗效好,结果具有统计学意义(均P<0.05);修复前各组患者龈沟液内AST、ALP表达水平无明显差异,修复后6个月及12个月玻璃陶瓷及二氧化锆组患者下降明显,其余组无明显差异,结果具有统计学意义(P<0.05)。结论:牙体缺损修复时应用玻璃陶瓷、二氧化锆较钴铬合金、银钯合金材料的治疗效果更佳,可以显著改善AST、ALP表达水平以降低牙周炎症反应,缓解前牙缺损临床症状。Objective To explore the effect of different kinds of gingival restorations,such as cobalt chromium alloy,silver palladium alloy,zirconia and glass ceramics,on the short-term and long-term treatment of patients with anterior teeth defects.Methods From February 2017 to April 2019,152 patients with anterior teeth defect were randomly divided into four groups:cobalt chromium alloy group,silver palladium alloy group,zirconium dioxide group and glass ceramic group,38 in each group.After the patients in each group were admitted to the hospital to complete the relevant examination,they were repaired with cobalt chromium alloy,silver palladium alloy,zirconium dioxide or glass ceramic materials respectively.The gingival index changes of each group before,6 months after and 12 months after the restoration were compared.The treatment effect of each group was compared and the patients in each group were followed up for 2 years to evaluate the long-term treatment effect of the patients The expression of AST and ALP in gingival crevicular fluid were compared before,6 months and 12 months after restoration.Results There was no significant difference in gingival index before treatment in each group.The gingival index of glass ceramic group and zirconia group decreased significantly in 6 months after repair,and that of glass ceramic group decreased significantly in 12 months after repair compared with the rest groups,with statistical significance(P<0.05).After treatment,the therapeutic effect of each group showed that the long-term effect of glass ceramic group was better than that of palladium silver alloy group There was no significant difference in AST and ALP expression level in gingival crevicular fluid between the groups before and after the repair,but there was a significant decrease in glass ceramics and zirconia group at 6 and 12 months after the repair,while there was no significant difference in the other groups(P<0.05).Conclusion The application of glass ceramic and zirconium dioxide in the restoration of tooth defect
