ObjectivesTo determine the clinical performance of long-term temporary fixed dental prostheses (LTFDPs) manufactured from CAD/CAM temporary resin-based composite.Materials and methodsRetrospective data of 46 patients supplied with 73 LTFDPs (partial coverage crowns, crowns, fixed dental prostheses) manufactured from a CAD/CAM resin-based composite luted either temporarily, selfadhsesively, or adhesively were analyzed for failures and complications.ResultsDatasets of 44 patients with 71 LTFDPs (12 partial-coverage crowns, 31 crowns, 28 fixed dental prostheses) were included in the analyses; median observation time was 362.0 days. Failures due to fracture occurred in 14.1% and decementation was observed in 18.1% of all LTFDPs. There was no statistically significant difference in failure rates between partial coverage crowns, crowns, and fixed dental prostheses. The probability of decementations was significantly higher in restorations that had been luted temporarily or selfadhesively than in those that had been luted adhesively.ConclusionsLTFDPs fabricated from resin-based temporary composite with low filler content feature relevant failure rates, which is independent on the type of restoration. Decementation is a frequently observed complication and dependent on the mode of luting.Clinical RelevanceLTFDPs fabricated from resin-based composite have similar failure rates as reported for polymethyl methacrylate based LTFPDs. Adhesive luting might help to reduce the probability of decementation.
