Abstract
All-ceramic fixed partial dental restorations are milled by CAD/CAM process. The significant challenges for such prostheses manufacturing are respecting functional and aesthetic requirements. Specific surface integrity (SI) might be manufactured in different anatomical and assembly prosthesis areas. Aesthetics, biological and mechanical responses require a low surface roughness. Contrariwise, the surface to be bonded needs to be sufficiently rough. The CAD/CAM process’s influence on prosthesis SI is not investigated in the industrial and scientific restorative dentistry community. This paper evaluates the influence of tools, biomaterials, and milling parameters on SI, especially the roughness, leading to topological decomposition of the prosthesis shape.
