- 3D-printed dental resin-based composites were evaluated for durability through an umbrella review.
- Mechanical, dimensional, optical, chemical, and clinical behaviors were analyzed.
- 3D-printed resins showed lower flexural strength, elastic modulus, fatigue resistance, and color stability compared to CAD/CAM-milled materials.
- Dimensional accuracy and marginal/internal fit were clinically acceptable but depended on washing, curing, and printing orientation.
- Short-term clinical evidence (6-24 months) was promising but insufficient for long-term conclusions.
- 3D-printed resins are viable for provisional and selected indirect restorations but lack long-term durability data.
- CAD/CAM-milled materials remain superior in mechanical and optical stability.
- Standardized protocols and more clinical trials are needed for reliable long-term recommendations.
