二氧化锆全瓷冠在前牙美学修复中的美观性与安全性分析

Aesthetic and Safety Analysis of Zirconia Full Porcelain Crown in Aesthetic Restoration of Front Tooth

目的分析探讨二氧化锆全瓷冠在前牙美学修复中的美观性与安全性。方法本次研究对象共30例,是我院行全瓷冠修复的患者,选取时间段为2019年1月至2020年5月。按照自愿分配原则,其中15例患者接受二硅酸锂玻璃陶瓷修复方法,视为参照组;另外15例患者接受二氧化锆全瓷冠修复方法,视为研究组。比较观察两组患者的牙冠色泽变化、并发症发生率变化和修复前后出血指数、牙龈指数和菌斑指数变化。结果经过治疗后,同参照组相比,研究组患者牙冠色泽变化发生率较低(4.44% VS 23.81%),数据比较差异较大(P<0.05);同参照组的并发症发生率相比,研究组显著较低(23.81% VS 47.62%),数据比较差异较大(P<0.05);两组患者修复前,出血指数、牙龈指数和菌斑指数相比,差异无统计学意义(P>0.05);经过治疗后,两组相关牙周健康指标均得到显著改善,但研究组更优(P<0.05)。结论从美观性与安全性角度出发,给予前牙修复患者二氧化锆全瓷冠治疗方法,治疗效果显著,其相比于二硅酸锂玻璃陶瓷冠修复方法更为理想,值得推广应用。

Objective This paper analyzes and discusses the aesthetics and safety of zirconia all-ceramic crown in the aesthetic restoration of anterior teeth.Methods A total of 30 patients in this study were patients undergoing all-ceramic crown restoration in our hospital.The selected time period was from January 2019 to May 2020.According to the principle of voluntary allocation,15 patients who received lithium disilicate glass ceramic repair method were regarded as the reference group;the other 15 patients who received zirconia all-ceramic crown repair method were regarded as the study group.To compare and observe the changes in crown color,complication rate,bleeding index,gingival index and plaque index before and after restoration in the two groups.Results After treatment,compared with the reference group,the incidence of changes in crown color of patients in the study group was lower (4.44%VS 23.81%),and the data were quite different (P<0.05).The incidence of complications was similar to the reference group Compared with the study group,the study group was significantly lower (23.81%VS 47.62%),and the data was quite different (P<0.05).There was no significant difference in the bleeding index,gingival index and plaque index of the two groups of patients before restoration (P>0.05).After treatment,the related periodontal health indicators of the two groups were significantly improved,but the study group was better (P<0.05).Conclusion From the point of view of aesthetics and safety,the treatment of zirconium dioxide full-ceramic crown for anterior teeth restoration is effective,and it is more ideal than that of lithium silicate glass.
