Fracture Resistance of Artificially Aged Three-Unit Interim Fixed Dental Prostheses: A Comparison of an Additively Manufactured Photopolymer, a Milled PMMA, and a Conventionally Autopolymerized PEMA-Based Resin
Interim fixed dental prostheses (FDPs) must withstand functional loading, thermal fluctuation, and moisture, yet comparative fracture resistance of additively manufactured, CAD/CAM-milled, and conventionally polymerized provisional materials after artificial aging remains unclear. Ninety three-unit interim FDPs (n = 30...
