Abstract
The roughness of dental prostheses surfaces, manufactured by CAD/CAM, is one of the major components of surface integrity (SI) to insure clinical success. This article aims at evaluating and quantifying the influence of the milling process characteristics on the roughness. First, the experimental results emphasize an influence of the tool grit size, the tool/prosthesis inclination and the biomaterials used on roughness. Then, based on these results, the definition of performance indicators for multi-physical and multi-indicator SI evaluation are proposed and implemented on a computer-aided tool to predict roughness. The use of this tool might help to proceed a topological decomposition of the crown to better respect the prosthetic specifications and to provide valuable assistance to the practitioner or the laboratory technician.
