3D-Printed Dental Resins Show 25% Lower Flexural Strength than Milled Composites

A study in Journal of Dental Research showed that 3D-printed dental resin-based composites exhibited a 25% reduction in flexural strength (60 MPa vs 80 MPa) and decreased optical stability over six months compared to CAD/CAM-milled counterparts, suggesting limited suitability for long-term definitive restorations.
