Description
The restorative materials that are used for all on four implant fixed prosthesis vary between PMMA, composite, translucent and high strength Zirconia. Most need internal reinforcement to function successfully in the oral environment. Historically support consisted of a cast gold bar, in recent years CAD/CAM milled titanium has been popularized. Today yet another support system has been developed. It allows the fabrication of a metal bar in about 20-30 minutes, at a fraction of the cost of current CAD/CAM bars. This presentation will show how a prefabricated modular system, when combined with modern printing and milling techniques, allows the fabrication of a final prosthesis near time of implant placement.
Upon completion of this presentation, participants should be able to: 1) list the advantages of a prefabricated bar system; 2) explain how to combine analog and digital technologies to maximize outcomes; and 3) recognize how the workflow for acrylic, composite and zirconia is nearly identical.
