Abstract:Objective To investigate the effect of zirconia post and fiber post in restoring the residual root and crown of upper anterior teeth.Methods A total of 61 patients with residual roots and crowns of upper anterior teeth who were admitted to the Third Affiliated Hospital of Xuzhou Medical University from February 2018 to December 2019 were selected as the research subjects.A total of 84 teeth were selected and divided into group A (30 cases,44 teeth)and group B(31 cases,40 teeth)according to the random number table method.Group A was repaired with fiber posts,and group B was repaired with zirconia posts.After the post-core crown restoration,the dentin shoulder collar and tooth body were prepared,and finally the porcelain crown was repaired and cemented.Both groups were followed up for 1 year.The success rate of restoration of residual roots,failure of restoration and chewing efficiency 1 year after restoration were compared in the two groups.Results There was no significant difference in the restoration success rate of group B(90.00%)and group A(77.27%)(P>0.05).In group B,the incidence of post-core loss or fracture,gingival inflammation,staining of the gingival margin,and root fracture was not statistically different from that of group A (P>0.05).The total effectiveness rate of chewing efficiency was compared between group B and group A one year after restoration of the tooth,and the difference was not statistically significant(P>0.05).Conclusion Both the zirconia post and the fiber post can achieve good therapeutic effects in the restoration of the residual root and crown of the upper anterior teeth,and there is no significant difference in the success rate or the effect on the patient′s chewing efficiency.Clinically,the appropriate one can be selected according to the patient′s specific situation.
