Conclusion
Machined surface integrity- Application to fixed dental prosthesis

This article presents the general concept of surface integrity and its application to CAD/CAM-formed dentures. These prostheses must respect several clinical functionalities expected by the practitioner and the patient, such as mechanical retention on the tooth, non-retention of dental plaque, wear of the prosthesis and the antagonist tooth, and prosthesis service life/fatigue.

The study of the correlation between surface integrity and prosthetic functionalities has established that roughness corresponds to a preponderant surface integrity component in dentistry, and has at least one correlation with all the clinical functionalities expected on a conjoint prosthesis. The correlation between prosthetic surface integrity and the machining process highlights the need to understand the mechanisms involved during dental CAD/CAM processing in order to improve prosthetic...
