4. Dental application: surface integrity of a dental prosthesis

The surface integrity of a CAD/CAM-finished dental prosthesis can be considered as the residual signature left by the machining process used, which determines the quality of the prosthetic surface obtained. The surface and sub-layers can be characterized according to various components linked to the clinical functionalities expected by the practitioner and the patient. Characterization of the surface integrity of a dental prosthesis is based on a set of multi-scale and multi-physical components and parameters that interact with each other.

Surface integrity is the indispensable intermediate concept between prosthesis fabrication and expected prosthetic clinical functionalities (figure 14 ), since direct "process-functionality" correlation (correlation...
