Effects of post‐curing light intensity on the trueness, compressive strength, and resin polymerization characteristics of 3D‐printed 3‐unit fixed dental prostheses
The light intensity of 210 mW/cm<sup>2</sup> exhibited the highest trueness, while the 840 mW/cm<sup>2</sup> group showed the highest deviation. However, the light intensity of 840 mW/cm<sup>2</sup> demonstrated the highest compressive strength. Furthermore, polymerization occurred at all post-treatment light intensities except 105 mW/cm<sup>2</sup>. These findings indicate that while low-intensity usage offers greater trueness, high-intensity usage provides better compressive strength and polymerization. Therefore, 210 mW/cm<sup>2</sup> could be the recommended solution for post-curing.
