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.

the number of occurance of Prosthetic complications
The prosthetic complications were evaluated for the three different types of Co-Cr frameworks The following prosthetic complications were evaluated: * abutment screw loosening * abutment screw fracture * prosthetic screw loosening * prosthetic screw fracture * acrylic teeth fracture (separation) * acrylic teeth wear (replacement) * co-cr framework fracture
Time frame: after a year
the implant framework Passive fit
the passivity of the framework was evaluated digitally using 3D scan protocol
Time frame: baseline
