PRINTOW: Occlusal Wear of Denture Teeth in Digitally Fabricated Complete Dentures
Starting soon · Not applicable
Conditions studied: Edentulism Complete, Edentulism
In brief
This randomized controlled trial evaluates the occlusal wear of denture teeth fabricated using three digital workflows: 3D-printed denture teeth, CAD/CAM-milled double cross-linked denture teeth, and prefabricated denture teeth. Occlusal wear will be assessed over 24 months using digital superimposition techniques. The study aims to determine whether 3D-printed denture teeth demonstrate superior wear resistance compared to CAD/CAM-milled denture teeth.
