The Role of CAD/CAM Systems in Oral Rehabilitation: Literature Review and Case Report

Main Article Content
Abstract
In dentistry, CAD/CAM systems have been applied and developed in clinical practice since 1971. Nowadays, digital workflow systems which utilize a combination of digital oral scanner and computer programs have been developed to assist prosthesis designing and manufacturing. Thus, dental prostheses are automatically designed and manufactured by the systems. CAD/CAM systems have many advantages. Firstly, more precise restorations are made by elimination of human errors that cause higher risk of mechanical failure. Moreover, the use of CAD/CAM systems provides further selection of dental materials usage such as zirconia that served the need in esthetic and function aspects. Finally, this technology consumes less time in treatment procedures that is more convenient for patients and dentists. This report shows the history and workflow of CAD/CAM systems, a comparison of CAD/CAM technique to conventional procedure, and a case report that used CAD/CAM systems to design and produce fixed and removable prostheses for oral rehabilitation.
