Management of Biotechnical Complications Associated with a Full‐Arch Implant Restoration Using Digital and Conventional Workflows: A Clinical Report

Full‐arch implant‐supported restorations using a metal‐acrylic resin design have had a high success rate but are also associated with frequent technical complications including framework misfit due to casting errors, debonding of denture teeth, and fracture of the acrylic from the metal framework. This clinical report describes a case of maxillary and mandibular full‐arch implant‐supported rehabilitation associated with technical and biological complications and use of digital technology for fabricating monolithic restorations. The use of a bio‐functional try‐in and its subsequent use as a conversion prosthesis for fabricating a master cast is described. The use of the patient's existing metal bar to fabricate a retread type prosthesis is also described along with using digital technology for fabricating a new metal bar and a monolithic type of restoration. The integration of digital and conventional workflows to obtain an increased level of accuracy and simplicity is also discussed.
