氧化锆全瓷修复与金属烤瓷修复对牙体缺损的修复效果及对牙周组织的影响

Effects of Zirconia All-ceramic Restoration and Metal-ceramic Restoration on Repair of Tooth Defects and Periodontal Tissue

目的:探讨与对比氧化锆全瓷修复与金属烤瓷修复对牙体缺损的修复效果及对牙周组织的影响。方法:2017年5月到2019年3月选择在本院进行诊治的牙体缺损患者112例,根据随机信封抽签原则把患者分为观察组与对照组,各56例。观察组使用氧化锆全瓷修复,对照组给予金属烤瓷修复治疗,记录修复效果及对牙周组织的影响。结果:修复后6个月观察组的修复体边缘密合度、颜色与形态评价合格率分别为98.2%、100.0%和94.6%,都显著高于对照组的87.5%、89.3%和76.8%(P<0.05)。两组修复后6个月的探诊深度(Pocket depths,PD)与牙龈指数(Gingi valindex,GI)值都高于修复前,观察组高于对照组(P<0.05)。两组修复后6个月的龈沟液肿瘤坏死因子(Tumor necrosis factor,TNF)-α与白介素(Interleukin,IL)-8值低于治疗前,观察组低于对照组(P<0.05)。观察组修复后6个月的牙龈炎、修复体断裂、继发龋等并发症发生率为7.1%,显著低于对照组的25.0%(P<0.05)。结论:相对于金属烤瓷,氧化锆全瓷修复牙体缺损能减少对牙周组织的影响,能抑制炎症因子的释放,从而提高修复效果,减少并发症的发生。

Objective:To explore and compare the effects of zirconia all-ceramic restoration and metal-ceramic restoration on the repair of tooth defects and periodontal tissue.Methods:A total of 112 patients with dental defects,who were diagnosed and treated in Second Affiliated Hospital of Nanjing University of Chinese Medicine from May 2017 to March 2019,were selected and were randomly divided into observation group(n=56)and control group(n=56).The observation group was repaired with zirconia all-ceramic,and the control group was given metal-ceramic repair treatment.The repair effect and the effect on periodontal tissue were recorded.Results:Six months after repair,the conformity rate of the restoration edge,color and morphology of the observation group were 98.2%,100.0%and 94.6%,which were significantly higher than those(87.5%,89.3%and 76.8%)of the control group(P<0.05).6 months after the repair,the pocket depths(PD)and gingi valindex(GI)values in the two groups were higher than before repair,the observation group was higher than the control group(P<0.05).The TNF-αand IL-8 values of gingival crevicular fluid 6 months after repair in the two groups were lower than before treatment,the observation group was lower than the control group(P<0.05).The incidence of complications such as gingivitis,prosthetic rupture,and secondary caries in the observation group was 7.1%,which was significantly lower than that(25.0%)in the control group(P<0.05).Conclusion:Compared with metal porcelain,zirconia all-ceramic repair of tooth defects can reduce the impact on periodontal tissue,can inhibit the release of inflammatory factors,thereby improve the repair effect and reduce the occurrence of complications.
