氧化锆全瓷修复体在后牙种植区应用134例的临床研究

A Clinical Study of 134 Cases of Zirconia in the Posterior Tooth Planting Area was Applied

目的探究氧化锆全瓷修复体在后牙种植区的临床应用效果。方法选取2014年6月~2016年6月在本院牙科进行后牙修复的134例患者,根据所用材料的不同,将其分为实验组(67例)与对照组(67例)。实验组采用氧化锆全瓷牙修复,对照组采用镍铬合金烤瓷牙修复,比较两组患者的修复体指标(边缘着色、龈缘密合度、修复涂颜色、修复体折裂)、牙周健康改善状况[包括探诊深度(PD)、菌斑指数(PLI)、出血指数(BI)、临床牙周附着丧失(CAL)]以及并发症发生率。结果实验组的修复体指标均优于对照组,比较差异具有统计学意义(P<0.05);实验组PD、PLI、BI、CAL均低于对照组,牙周健康状况优于对照组,比较差异具有统计学意义(P<0.05);实验组并发症发生率(7.46%)低于对照组(19.40%),比较差异具有统计学意义(P<0.05)。结论氧化锆全瓷修复体可有效提高后牙种植修复率,改善牙周健康,降低并发症发生率,可在临床上广泛应用。

Objective To explore the clinical application effect of zirconia in the posterior tooth growing area. Methods A total of 134 patients were selected from June 2014 to June 2016, according to different materials, it can be divided into experimental group（67 cases） and control group（67 cases）, the experimental group was using the zirconia ceramic repair, the control group with nickel chromium alloy porcelain teeth restoration, compared two groups of patients restoration index（edge coloring, transparent colour fit, repair, restoration fracture）, periodontal health improve performance（including agent diagnosis depth（PD）, plaque index（PLI）, bleeding index（BI）, clinical periodontal attachment loss（CAL） and the incidence of complications. Results The recovery indexes of the experimental group were better than the control group, and the difference was statistically significant, P 〈 0.05. The experimental group PD, PLI, BI and CAL were all lower than the control group, and the periodontal health was better than the control group, and the difference was statistically significant, P 〈 0.05; The incidence of complications of the experimental group（7.46%） was higher than that in the control group（19.40%）, and the difference was statistically significant, P 〈 0.05. Conclusion The restoration of zirconia can improve the recovery rate, improve periodontal health and reduce the incidence of complications, which can be widely used in clinic.
