Abstract: Objective: To compare the clinical effects of two tooth-colored improved onlay/crown restorations in the seriously damaged molars. Methods: A total of 51 onlay/crowns restorations were placed in 46 patients. The restorations were allocated into CAD/CAM zirconia ceramics and Co-Cr PFM onlay/crowns. According to modified USPHS criteria, all improved onlay/crowns were checked and recorded at 1 week, 1 year and 2 year after the restorations were placed. Results: Only one Co-Cr PFM onlay restoration was broken on the ceramic layer at the second year. There were no restoration loss, tooth fracture and secondary caries during the study. Three CAD/CAM zirconia ceramics and 7 Co-Cr PFM restorations were little mismatch in color with adjacent teeth. Conclusion: Improved tooth-colored onlay/crown restoration provides the dentists with another treatment choice for seriously damaged posterior teeth. However, long-term observation is necessary.
