Overview

In vitro comparative study demonstrates superior dimensional accuracy and color stability in CAD-CAM milled denture base resins, suggesting milling offers superior durability over 3D printing.

Key Points

  • CAD-CAM milled denture base resins maintained superior dimensional accuracy and color stability across aging protocols, significantly outperforming 3D-printed and conventional materials.
  • Thermocycling across 5000 cycles reduced dimensional accuracy in heat-polymerized and 3D-printed resins, whereas CAD-CAM milled resins exhibited no significant dimensional changes.
  • Assessment using 3D-surface matching and spectrophotometer analysis of 54 specimens shows cleansers increase color change, highlighting limitations in 3D-printed resin longevity.
