ABSTRACT

OBJECTIVES: This study aimed to compare the outcome of a simplified direct composite resin-bonded fixed dental prostheses without reinforcing fibers (CR-RBFDP) and resin-bonded fixed dental prostheses using zirconia (Zr-RBFDP).

METHODS: The clinical records of five private practice dental clinics and one university hospital were analyzed. Failure was defined as a RBFDP that was removed or remade for any reason. Survival analyses were performed using log-rank tests.

RESULTS: A total of 45 patients (CR-RBFDP, n = 17; Zr-RBFDP, n = 28) were followed up for 3 years. Among the CR-RBFDP cases, 1 case of framework fracture and 2 cases of discoloration occurred, whereas among the Zr-RBFDP cases, 1 case of debonding occurred. The mean duration of observation was 21.9 months. The 3-year survival rate was 92.3 % for CR-RBFDP and 91.7 % for Zr-RBFDP. Log-rank test showed no significant difference (p = 0.78).

CONCLUSIONS: Within the limitations of this short-term retrospective study, the survival rate of CR-RBFDP was not significantly different from that of Zr-RBFDP. Contrary to concerns regarding material strength, CR-RBFDP showed reliable results. This direct composite restoration has the advantages of being less invasive and being completed in a single visit.

CLINICAL SIGNIFICANCE: Despite differences in material strength, CR-RBFDPs without fiber reinforcement showed reliable short-term clinical results. This direct composite restoration has the advantage of being less invasive and can be restored in a single visit.

ABSTRACT

This study aimed to evaluate the effects of different resin-coating technique strategies and dual-cure resin luting materials on proximal marginal adaptation and the microtensile bond strengths (μTBSs) of CAD/CAM hybrid ceramic inlays. Extracted human molars were classified into four groups, depending on the coating technique: No coating (None), single coating (1-coating), double coating (2-coating), and flowable resin-coating (Combination). The inlays were bonded with one of the three materials: Panavia V5 (V5), Rely X Ultimate (RXU), and Calibra Ceram (CC). The differences with regard to adaptation were not significant. In the case of μTBS data for V5, no significant differences were observed, whereas for RXU, μTBS values for Combination statistically exceeded those for None and 1-coating. For CC, μTBS values for Combination statistically exceeded those for None, 1-coating, and 2-coating. The coating techniques did not influence the adaptation but influenced the bond strength, and Combination performed the best.
