The Effect of Different Surface Treatments and Thermocycling on Repair Bond Strength of a 3D-Printed Permanent Crown Resin
The aim of this study was to investigate the effects of surface treatments and thermocycling on the shear bond strength of a 3D-printed permanent crown resin. A total of 120 disc-shaped specimens (10 × 3 mm) were fabricated using a 3D printer and randomly assigned to four groups according to surface repair protocols: a...
