Study on the Use of Digital Technology in the Realization of Prosthetic Restorations

Abstract

The use of digital technology has become a useful and also a preferred process in the realization of dental prosthetic restorations, because through it, superior quality dental prostheses are obtained in terms of aesthetics, accuracy of execution and durability. CAD/CAM technology is changing all aspects of dentistry, making dental restoration processes much easier and more efficient for dentists, patients and dental technicians. The materials that can be used to manufacture dental restorations designed using Exocad software depend on the type of restoration (crowns, bridges, veneers, etc.) and the manufacturing method (milling with a 3-, 4-, or 5-axis CAM device); available materials include: PMMA (polymethyl methacrylate) and zirconia. Using digital technology, in this study we performed 6 fixed prosthetic restorations, of which 5 unidental restorations (5 dental crowns) and 1 pluridental restoration (a 4-element dental bridge); of the 6 prosthetic restorations, 3 restorations will be fixed by cementing on dental abutments, and 3 restorations will be fixed by screwing on implants. Digital technology allows the use of higher quality materials, resulting in more resistant and more aesthetic prosthetic restorations; helps reduce the occurrence of errors; obtaining a better marginal adaptation and a perfect adaptation to the anatomical structures of the patient s teeth.
