Assessing shear bond strength of various surface treatments of 3D-printed provisional material with bis-acryl relining material.

Objective: Marginal adaptation of the provisional restoration often requires relining from relining materials. This study determined the effects of surface treatments on the shear bond strength (SBS) between 3D-printed provisional and bis-acryl relining materials.

Materials And Methods: The 3D-printed provisional specimens (9 × 9 × 2 mm) were prepared using methacrylate-based material.
