Influence of post-printing cleaning solutions on the occlusal wear and fracture resistance of 3D printed resin-based crowns after thermomechanical aging.

Researchers compared how different cleaning solutions affected the wear and fracture resistance of two types of 3D-printed resin crowns, with and without simulated aging. The urethane acrylate resin showed greater wear than the glass-filled composite resin, while cleaning solution choice influenced wear depth but fracture resistance effects varied by resin type and aging status.
