Fracture resistance of direct versus CAD-CAM PMMA provisional restorations: An in vitro study
Year: 2025
Type: article
Abstract: The fracture resistance of polymethyl methacrylate (PMMA)-based provisional crowns fabricated using two techniques: conventional direct and Computer-Aided Design/Computer-Aided Manufacturing (CAD-CAM) milling is of interest to dentist. Hence, sixty extracted premolar teeth were restored and tested under simulated occlusal forces. Data showed that CAD-CAM milled restorations exhibited significantly higher fracture resistance than conventionally fabricated crowns. The study shows the mechanical superiority and clinical reliability of CAD-CAM technology. Thus, we show support its use for improved provisional restoration outcomes.
