Digital Removable Partial Denture Fabrication Using an Intraoral Scanner and the Altered-Cast Technique for a Patient With Free-End Partial Edentulism: A Case Report

TL;DR

A patient with missing teeth received a custom denture using digital scanning and a special casting method, resulting in a functional and comfortable prosthesis.

Contribution

This case report demonstrates a novel integration of intraoral scanning and the altered-cast technique for fabricating removable partial dentures.

Findings

Digital scanning provided accurate anatomical impressions of teeth and ridges.

The altered-cast technique improved the fit and function of the denture.

The patient reported satisfaction with the denture's stability and performance.

Abstract

This clinical report describes treatment with a removable partial denture produced using an anatomical impression made with an intraoral scanner and a mucocompressive impression made using the altered-cast technique. First, digital scanning was performed with an intraoral scanner to obtain an anatomical impression of the remaining teeth and the residual ridges. Computer-aided design software was then used to design the framework, which was fabricated by selective laser melting. A mucocompressive impression was subsequently made using the altered-cast technique, and gypsum was poured to modify the cast accordingly. The denture was then fabricated. The patient was satisfied with the stability, retention, and overall function of the prosthesis.
