Maxillary and mandibular screw retained fixed full arch pfm restoration – A Case Report

The fabrication of a full-arch implant supported maxillary and mandibular prosthesis has been associated with several prosthetic complications and difficulties. Even though it has been reported that phonetics, esthetics, and proper lip support are difficult to achieve with fixed full arch implant supported, there is a scarcity in the literature regarding the clinical and laboratory procedures necessary to minimize these complications. This article provides clinical and laboratory steps that may enable the clinician to achieve more predictable restorative results when using computer-aided design/computer-assisted manufacture (CAD/CAM). The technique presented here describes the fabrication of a wax pattern of the metal framework using CAD/CAM followed by casting to fabricate a maxillary and mandibular implant supported porcelain fused to metal restoration in a more predictable manner.
