Abstract: Objective: To analyze and compare the effect of residual crown and root's repairment by glass fiber post and pure titanium post. Methods: 235 patients (334 teeth) with residual crown or residual root in the time period of September, 2013 to March, 2017 were selected. In accordance to the admission time and patient's will, patients were divided into two teams. Patients' defect were repaired by crown and tracked by 3 years. Results: No significant difference was found on the general success rates, anterior teeth success rates, premolar success rates, and metal team's success rate (P>0.05). There was a significant difference on the anterior teeth success rate and the posterior teeth success rate of fiber team (P<0.05). On the basis of the appearance and comfort survey which responded by patients from successful cases, 94.55% patients from fiber team had feedbacks of "strongly satisfied". Such satisfaction rate was higher to the metal team. Conclusion: At current time, repairment of residual crown and root by glass fiber post and titanium post were ideal treatments.
