Evaluating the effect of surface treatments and adhesive systems on shear bond strength and microleakage in 3D permanent resin denture bases

The study found that applying Group A (2.50 ± 1.47 MPa) weakened the bond, while Group T (3.78 ± 2.63 MPa) had lower values than Group C (13.52 ± 1.37 MPa). Among the adhesive systems, bond application showed the best performance. The application of surface treatment decreases bond strength with reduced microleakage. These findings emphasize the importance of selecting appropriate adhesive systems for 3D-printed complete dentures in clinical applications. It shows the best ways for both clinicans and patients to bond in order to meet the mechanical and aesthetic needs that come up with long-term prostheses use.
