Il workflow estetico funzionale. Il successo tra tradizione e innovazione

Abstract

ObjectivesComplex prosthetic reconstructions based on CAD/CAM technology are becoming more and more popular; they range from the simplest reconstructions based on two abutments to the more complex, involving entire dental arches. The reliability of these reconstructions is now under review, as there are more and more contributions in literature to support them. The purpose of this paper is to analyse contributions related to this topic and to provide clinical examples in this regard. Materials and methodsPapers relating to complex prostheses made by CAD/CAM systems were examined and articles concerning useful issues for the goals of this work were selected; the emerged scientific evidence was consequently reported. Furthermore, some cases typifying possible complex reconstruction procedures were considered. In addition, a careful examination of the workflow between the dental practice and dental laboratory was made. Results and conclusionsThe materials available for prosthetic reconstructions are varied and can be made with traditional methods and/or processed through CAD/CAM systems: apart from metallic materials, feldspathic ceramics or glass ceramics attached or not to zirconia have proven effective in replacing traditional techniques founded on the union between metals and ceramics. Long term durability of bridges or entire dental arches obtained with milling systems stands at above 80% after observation periods exceeding 10 years. However, some problems should be considered: the literature data reveal that the operators’ experience and the tooth structure preparation techniques can affect significantly the final result.
