Analysis of the Clinical Efficacy of All-porcelain Restoration for 69 Cases with Tooth Defect

Objective To explore the clinical efficacy of all-porcelain restoration for 69 cases with tooth defect.Methods 138 cases with tooth defect admitted in our hospital from May 2012 to April 2014 were selected and randomly divided into the observation group and the control group with 69 cases in each.Patients in the control group were treated with the conventional compos-ite resin restoration,and patients in the observation group were treated by all-porcelain restoration.6 months after treatment,the treatment effect and incidence of adverse reactions of the two groups were observed and recorded.Results 6 months after treatment,the follow-up given to the patients showed that,the tooth color fidelity factor,normal chewing rate,periodontal healthy rate and adjacent good rate of the observation group was 75.4%,92.8%,84.1%,81.2%,respectively,significantly better than that of the control group,respectively;in addition,the incidence of adverse reactions of the observation group was 24.6%(17 cases),obviously lower than 89.9%(62 cases) of the control group,the difference was statistically significant(P0.01).Conclusion For patients with tooth defect,all-porcelain restoration can effectively improve the treatment effect and reduce the incidence of adverse reactions,so it is worthy of clinical application and promotion.
