| Purpose: To evaluate clinical performance of fiber reinforced composite base and bonded CAD/CAM resin composite endocrowns compared to lithium disilicate endocrowns over one year. Methods: A total of 110 endocrowns, 55 lithium disilicate endocrowns (group I) (IPS e. max CAD) and 55 of bonded CAD/CAM resin composite endocrowns with fiber reinforced FRC base (group II) (Grandio) were used to restore endodontically treated molars. First shade selection was performed followed by cavity preparation and digital impression. Then restorations were designed, milled and checked intraorally before cementation using resin cement. The restorations were evaluated at baseline, 6 and 12 months using Modified USPHS criteria. Statistical analysis was performed with SPSS 20®, Graph Pad Prism® and Microsoft Excel 2016. Results: Regarding fracture and marginal adaptation, all restorations in both groups had Alpha score (100%); at base line, after 6, and 12 months. Regarding retention, all restorations in both groups had Alpha score (100%); at base line, and after 6 months. While after 12 months, only one case had Charlie score in group I with insignificant difference between groups as P=0.32. Regarding shade match, all restorations in both groups had Alpha score (100%); at base line while after 6 months two cases were Bravo in group II with insignificant difference between groups as P=0.14. While after 12 months, three cases were Bravo in group II with insignificant difference between groups as P=0.07. Conclusion: CAD/CAM resin composite endocrowns with fiber reinforced FRC base are just as dependable as lithium disilicate for restoring non-vital posterior teeth. | ||||
