Method & Evidence

AimTo investigate how different surface treatments, including resin coating, affect the shear bond strength between CAD/CAM composite resin blocks and luting agents.

MethodExperimental comparative study

ProcedureComposite resin blocks for CAD/CAM were subjected to various surface treatments: no treatment, conventional silane, universal silane, universal silane after silica coating, resin coating after universal silane, and universal silane after silica coating and resin coating. All specimens were air-abraded. Shear bond strength was tested, and surface roughness was measured to assess fitting accuracy.
