A dental technique to reseat an angled nonhexagon multiunit abutment in a complete arch fixed prosthesis

When an angled abutment lacking an antirotation structure within a complete arch implant- supported fixed prosthesis becomes loose, the conventional approach typically involves replacing the entire prosthesis because of the difficulty of reseating the abutment at its original angle. To address this predicament, this technique article describes a novel solution in the form of a resin verification guide that replicates the maxillary prosthesis. The modified cylinder enables tightening of the abutment screw of the reseated multiunit abutment in place, eliminating the need for replacing the prosthesis and reducing treatment costs and duration.
