Effects of Printing Orientation and Laser Surface Treatments on the Shear Bond Strength of 3D-Printed Hybrid Materials: An In Vitro Study.

Description :

Dentistry is rapidly evolving, with ongoing advances in materials and innovative techniques, including 3D- printed resins and laser technologies designed to improve clinical performance and patient outcomes. In this study, 3D-printed hybrid resin–ceramic specimens will be fabricated at four printing orientations (0°, 30°, 45°, and 90°), subjected to surface treatments using either conventional sandblasting or laser irradiation (Er: YAG and Er, Cr: YSGG), and evaluated for SBS to a flowable resin composite. The goal is to determine the optimal combination of printing orientation and laser treatment to enhance clinical outcomes.
