A technique to enhance the gingival esthetics of a prototype complete arch fixed implant-supported prototype prosthesis using a 3D printed gingival veneer.

Abstract

An important step in the workflow for a complete arch fixed implant-supported prosthesis is the fabrication of a prototype resin prosthesis to allow the patient to visualize the definitive treatment outcome and also to use as an interim prosthesis. Producing a prototype prosthesis with the natural appearance of the gingival color and contour has been challenging. Current methods include painted stains, manually applied pink composite resin or autopolymerizing acrylic resin, and multicolored resin blocks, but these are all relatively expensive, have less than optimal esthetics, and are labor-intensive and time-consuming. This technique article describes a digital workflow to design and fabricate a complete arch 3D printed gingival veneer that can be directly bonded onto a white prototype resin prosthesis to enhance gingival esthetics. Additional technical details related to the design and fabrication of the separate pink and white components and bonding and sealing them together are also provided.
