No results posted yet for this study

Summary

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.

Interventions

DEVICE

CAD/CAM-Milled Denture Base with Milled Denture Teeth

Complete removable dental prostheses fabricated using a digital workflow with CAD/CAM milling. Both the denture base and denture teeth are produced by subtractive manufacturing from pre-polymerized resin materials, including double cross-linked denture teeth, and assembled.

DEVICE

CAD/CAM-Milled Denture Base with Prefabricated Denture Teeth

Complete removable dental prostheses fabricated using a digital workflow with CAD/CAM-milled denture bases combined with conventionally manufactured prefabricated denture teeth. The prefabricated teeth are selected and positioned digitally or manually and then bonded to the milled denture base.

DEVICE

3D-printed denture base and teeth

Description Complete removable dental prostheses fabricated using a fully digital workflow in which both the denture base and denture teeth are produced by 3D printing using light-curing resin materials. The prostheses are designed digitally and manufactured additively.
