Fracture Resistance and Failure Modes of Cuspal-coverage Restorations Using Fiber-reinforced and Non-fiber-reinforced Materials: An In Vitro Study
Year: 2025
Type: article
Abstract: BACKGROUND: study was to determine the fracture resistance and failure mode of direct cuspal-coverage restorations utilizing fiber-reinforced and non-fiber-reinforced materials. MATERIALS AND METHODS: tests (α = 0.05). RESULTS: = 0.884). The MS-SFRC + NC group had the greatest percentage of adhesive failures (70%), and the AM group had the greatest percentage of cohesive failures (80%). The NS-SFRC group had the greatest percentage of failures of the tooth/restoration complex with periodontal involvement (40%) and both the NC and PF + NC had the greatest percentage of failures of the tooth/restoration complex without periodontal involvement (20%). CONCLUSIONS: The MS-SFRC + NC group had the highest fracture load and was significantly greater than all other groups-which were not significantly different from each other: MS-SFRC + NC > PF + NC = AM = NS-SFRC = NC. The observed fracture mode for the MS-SFRC + NC group was predominantly adhesive, resulting in an overall repairable failure mode. CLINICAL SIGNIFICANCE: Study. J Contemp Dent Pract 2025;26(1):4-9.
