摘要
目的观察二氧化锆修复体在口腔修复中的疗效。方法选取2017年3月至2018年1月来本院就诊的72例口腔修复患者作为研究对象,根据修复体的不同分成对照组(35例)和实验组(37例),其中对照组采用金属烤瓷修复体,实验用采用二氧化锆修复体。观察两组患者治疗后的效果。结果实验组治疗后的咬合边缘密合性合格率为100.00%,明显高于对照组的82.86%,差异有统计学意义(P<0.05);实验组的修复体折断率及崩瓷率分别为2.70%,5.41%,均明显低于对照组的13.51%,21.62%,差异有统计学意义(P<0.05)。治疗后实验组患者没有出现牙龈色泽改变情况,对照组的牙龈色泽异常率为37.14%,差异有统计学意义(P<0.05)。实验组治疗后的0~Ⅰ级牙龈沟出血指数和Ⅱ~Ⅴ级牙龈沟出血指数分别为91.89%,8.11%,对照组的分别为71.43%,28.57%,差异有统计学意义(P<0.05)。结论二氧化锆修复体咬合边缘密合性优良,不易折断和崩瓷,能够有效的减少牙龈变色和牙龈沟出血情况,具有美观性好,疗效确切的优势,值得在临床大力推广。
Objective To observe the effect of zirconium dioxide prosthesis in dental prosthesis.Methods 72 cases of prosthodontic patients in our hospital from March 2017 to January 2018 were selected as the research objects.They were divided into control group(35 cases)and experimental group(37 cases)according to the different prostheses.The control group was treated with metal-ceramic prostheses and the experimental group was treated with zirconia prostheses.Observe the effect of two groups of patients after treatment.Results After treatment,the qualified rate of occlusal marginal occlusion in the experimental group was 100.00%,significantly higher than that in the control group 82.86%(P<0.05);the broken rate and broken porcelain rate in the experimental group were 2.70%,5.41%,respectively,which were significantly lower than those in the control group 13.51%,21.62%(P<0.05).There was no change of gingival color in the experimental group after treatment.The abnormal rate of gingival color in the control group was 37.14%.The difference was statistically significant(P<0.05).Grade 0-I and Grade II-V gingival sulcus hemorrhage index were 91.89%and 8.11%in the experimental group and 71.43%and 28.57%in the control group after treatment,respectively,with statistical significance(P<0.05).Conclusion Zirconium dioxide prosthesis has excellent occlusal marginal cohesion,is not easy to break and collapse porcelain,can effectively reduce gingival discoloration and gingival sulcus bleeding,has the advantages of good aesthetics and exact curative effect,and is worthy of vigorous promotion in clinical practice.
