Investigates how thermal aging affects surface roughness in intraoral appliance materials, suggesting material choices for durability.
Materials used for the fabrication of intraoral appliances exhibit material-specific responses to thermal aging. The light-cured UDMA-based resin demonstrated superior surface integrity after aging, whereas conventional PMMA and the 3D-printed resin were more susceptible to surface alterations.
