Application of Digital Techniques for the Observation and Fabrication of Removable Partial Dentures.

This study explores digital fabrication of removable partial dentures (RPD) via direct intraoral model observation. At initial diagnosis, the three-dimensional design scheme is obtained directly by visualizing the digital model using an intraoral scanner and a three-dimensional management platform software. This framework supports tooth preparation, data acquisition, digital chair-side observations, and RPD design and fabrication.
