| Abstract: | Objective: The clinical effects on the repair of the residual roots of the front teeth by using the fibrousposts and resin nuclear joint full crowns are explored. Methods: 21 residual roots of the front teeth repaired by using thefibrous posts and resin nuclear joint full crowns were followed up for 2 years after restoration was completed. Results: Oneresidual root one year after repair became luxated with a failure rate of 4. 76% while the rest of the cases had perfect crownsof the artificial teeth without luxated, deciduous fibrous posts.The X-ray films showed that the dental roots and fibrousposts were not broken and dental periodontal tissue and apex had no shadow. Conclusions: It is a good method of restora-lion to use glass fibrous posts and resin nuclear joint full crowns to repair the residual roots of the front teeth. |
