Abstract

Extreme residual ridge resorption is a challenging clinical situation for the fabrication of complete dental prostheses. Computer-aided design and computer-aided manufacturing (CAD/CAM) complete dentures have been shown to have superior fit and material strength to conventionally fabricated dentures, but no clinical protocols have been described for cases of extreme residual ridge resorption. This report describes a workflow combining conventional and novel techniques for CAD/CAM complete dentures fabrication for atrophic alveolar ridges and demonstrates that a CAD/CAM workflow is an effective tool for solving this complex situation.

Highlights

It has been shown that edentulism is the final result of a multifactorial process comprising biological and patient-related factors [1]
Complete edentulism has decreased in developed countries, but it still remains a significant problem a group that varies from 15% to 54% of the senior population [2]
Well-fitted removable complete dentures reduce the occurrence of traumatic ulcers and show higher comfort when wearing prostheses [5]

Summary

Introduction

It has been shown that edentulism is the final result of a multifactorial process comprising biological and patient-related factors [1]. Well-fitted removable complete dentures reduce the occurrence of traumatic ulcers and show higher comfort when wearing prostheses [5]. The production of complete dentures using conventional techniques and materials such as monomers can cause an allergic reaction in some patients, regardless of the curing method [8]. All of these problems have been solved by the digital workflow for denture fabrication, because milled resin pucks contain negligible unpolymerized monomers, the dentures are made from highly crosslinked pucks, and fabrication time is considerably decreased, even if novel and traditional fabrication are combined [9]. Recent studies have claimed higher retention and fit of computer-aided design and computer-aided manufacturing (CAD/CAM) fabricated dentures than those conventionally fabricated [10]
