Conventional compared to CAD/CAM ceramic inlay

Abstract

Objectives. This study aimed at comparing the methodologies for achieving an occlusal-mesial ceramic inlay using both the conventional and digital methods in terms of workflow protocol, aesthetic and functional results, working time, but also costs and equipment needed. Material and methods. A 22-year-old patient presented with a direct mesio-occlusal composite restoration with a secondary marginal decay in tooth 3.6 that was subsequently restored by a ceramic inlay manufactured using both traditional and digital methods. Outcomes. The dental technician's talent, experience, and vision guided the technical process of creating the conventional inlay. The technical process of producing the digital inlay involved fewer laboratory stages, but also contamination risks than conventional ones, removing potential human errors associated with each stage and allowing possible changes to be made more quickly and efficiently. The conventional method took more time to complete all of the laboratory steps than the digital method. Conclusions. When compared to the digital method, the traditional method allowed the dental technician to achieve a high level of individualization of the prosthetic restoration. Digital techniques are a method of the future that is rapidly growing and improving. Digital techniques for obtaining an inlay involved high-performance equipment, which is pricey to purchase and maintain.
