PEEK Vs Titanium for All-on-4 Prosthesis

For the PP, The PEEK framework will be constructed, the fit of the PEEK framework will be verified intraorally, and the final screw-retained prosthesis will be constructed of PMMA teeth and a visiolign pink composite estimating the gingival tissue.

For the TP, the framework will be milled from Ti blocks according to the virtual design of the final prosthesis framework. PMMA teeth then will be cemented, and the final prosthesis will be screwed.
