Influence of ZrO Nanoparticle Addition on the Optical Properties of Denture Base Materials Fabricated Using Additive Technologies.

This study investigated the translucency of 3D-printed denture base resins modified with zirconium dioxide nanoparticles (ZrONPs) under thermal cycling. A total of 110 specimens were fabricated and divided into 3 groups according to the materials, i.e.
