Methods: A total of 100 specimens (65x10x2.5 mm) were fabricated using two types of denture base materials: pre-polymerized PMMA-based blocks designed for CAD/CAM milling and conventional heat-polymerized denture base acrylic resin (control). The specimens were sectioned in the middle with 2 mm repair gap and 45° margin design. Repair surfaces were first treated with various light-cured bonding agents then repaired using VLC resin. The bonding agents either conventional or combined with acrylic primers and dual cure agents were tested. All the specimens were subjected to 3-point bending test and FS was calculated. Data were statistically analyzed using two-way analysis of variance according to the denture base material and the bonding treatments (p <0.05). Results: Among repaired groups, acrylic primer + G-Premio BOND produced the highest FS within each material (A3: 17.31±4.69 MPa; B3: 9.80±2.57 MPa). Between materials, CAD/CAM exceeded conventional in groups 1-4 (p <0.05)-including the intact controls-whereas group 5 showed no between-material difference (p>0.05). Conclusion: The use of a bonding agent specifically designed for the surface treatment of acrylic resins can be clinically beneficial when repairing denture bases with VLC resin.}, number={5}, publisher={MediHealth Academy Yayıncılık}
