Clinical effect observation of two types post for upper anterior teeth restoration in varying degrees defects

Objective To observe and evaluate the long-term clinical effect of glass fiber post core and Au-Pt alloy post core for anterior teeth restoration in varying degrees defects.Methods Glass fiber post core(group A,81cases,172 teeth) and Au-Pt alloy post core(group B,86cases,149 teeth) were used for 321 anterior teeth restoration in three degrees defects.After two years follow-up,we observed the restoration effect.Results In the different degrees,the success rate are 85.42%、98.61% and 98.08%,the overall rate is 94.77% in group A,whether the success rate are 82.5%、82.22% and 84.38%,the overall rate is 83.22% in group B.There was statistically significant difference between two groups except the first degree.Conclusion Glass fiber post and light-cure resin core has better clinical effect than Au-Pt alloy post core used to restore residual crown and root of upper anterior tooth.
