Comparison of Prosthetic Complications and Framework Misfit Among Different Cobalt-Chromium Framework Fabrication Techniques

This randomized clinical study aimed to compare prosthetic complications and framework misfit associated with three different fabrication techniques of cobalt-chromium frameworks-conventional casting, CAD/CAM milling, and selective laser melting (SLM)-used in maxillary and mandibular full-arch implant-supported acrylic screw-retained restorations.
