Influence of CAD/CAM diamond bur wear on the accuracy and surface roughness of dental ceramic restorations: A systematic review.

Objectives: To systematically review the current literature investigating the computer-aided design/computer-aided manufacturing (CAD/CAM) diamond bur deterioration with repeated use and its effects on the accuracy, marginal and internal fit, and surface roughness of the dental ceramic restorations from the subtractive manufacturing technique.

Materials And Methods: Three online databases, Ovid, Scopus, and Web of Science, were screened up to February 2024. In vitro studies investigating bur wear and its influences on subtractively-manufactured (SMed) ceramic restorations, except zirconia, were included.
