Tensile bond strength of soft relining materials to CAD-CAM denture base materials

This study aimed to investigate the tensile bond strength between soft relining materials and different denture base materials. The study was conducted in accordance with ISO 23401:2023. A total of 288 rectangular specimens (10L × 10H × 20W mm) were fabricated from various denture base materials, in...

Description
Summary:This study aimed to investigate the tensile bond strength between soft relining materials and different denture base materials. The study was conducted in accordance with ISO 23401:2023. A total of 288 rectangular specimens (10L × 10H × 20W mm) were fabricated from various denture base materials, including a heat-compression polymethylmethacrylate (PMMA), two types of milled PMAA, and three types of 3D-printed resins, with bonding using two chairside soft reline materials (Coe-Soft and Lynal). Specimens were placed in distilled water for 24 h before applying tensile force at a 5 mm/min crosshead speed. The tensile bond strength values (MPa) were calculated at maximum tensile force (N) before failure. Two-way ANOVA and post hoc multiple comparison tests were used to assess the effect of denture base and soft reline materials on the tensile bond strength (α = 0.05). A significant difference in the tensile bond strength was found among the different types of denture base materials (p
