Enhancing Fracture and Wear Resistance of Dentures/Overdentures Utilizing Digital Technology: A Case Series Report

Abstract

Since it was first introduced into the dental world, computer-aided design/computer-aided manufacturing (CAD/CAM) technology has improved dramatically in regards to both data acquisition and fabrication abilities. CAD/CAM is capable of providing well-fitting intra- and extraoral prostheses when sound guidelines are followed. As CAD/CAM technology encompasses both surgical and prosthetic dental applications as well as fixed and removable aspects, it could improve the average quality of dental prostheses compared with the results obtained by conventional manufacturing methods. The purpose of this article is to provide an introduction into the methods in which this technology may be used to enhance the wear and fracture resistance of dentures and overdentures. This article will also showcase two clinical reports in which CAD/CAM technology has been implemented.

Polyetherketoneketone (PEKK): An emerging biomaterial for oral implants and dental prostheses

“…It can be a potential material for application as a restorative material in fixed prosthodontics [34] , [38] . Computer-aided design (CAD) and computer-aided manufacturing (CAM) technologies have increased accuracy and made it easier for the fabrication of modern restorative and prosthetic materials [39] , [40] , [41] . Individual ceramic produced from CAD/CAM can be incorporated in the complete denture to increase their wear resistance [40] , [41] , [42] .…”

Reinforcement of Single Implant‐Retained Mandibular Overdenture with a Cobalt‐Chromium Framework before Implant Surgery

“…A cobalt‐chromium (Co‐Cr) framework immersed at the denture base has been used in overdentures supported by two implants in order to prevent its fracture . Regarding single implant‐retained mandibular overdentures, studies have suggested the inclusion of a metallic framework reinforcement such as a strengthened instrument inside the denture base.…”

“…A cobalt-chromium (Co-Cr) framework immersed at the denture base has been used in overdentures supported by two implants in order to prevent its fracture. 12,13 Regarding single implant-retained mandibular overdentures, studies 5,14 have suggested the inclusion of a metallic framework reinforcement such as a strengthened instrument inside the denture base. A clinical report by Grageda and Rieck 15 described an edentulous patient with no complications after 2 years of using a conventional maxillary complete denture and single implant-retained mandibular overdenture reinforced by a metal framework.…”

Comparative Evaluation Of Physical Properties Of Conventionally Constructed Versus CAD/CAM Milled Frameworks For Kennedy Class I Partial Dentures

“…In the near future, CAD/CAM may well become the preferred fabrication method for most dental prostheses. 13 There is no definte study shows difference in mechanical and physical properties of either milled or pressed frameworks. In this study it was clear that CAD/CAM method of fabrication is better was than pressedthis study, it was concluded that PEEK based restorations shows better surface properties than those of PMMA based materials so it can be used for long term restorations.…”
