Brief Summary

The goal of this observational study is to evaluate the outcome of a Poly-ether-ether-ketone - used in partial implant-supported rehabilitations after one year of follow-up. The main question it aims to answer is: \- What is the survival outcome of partial implant-supported prosthesis using Poly-ether-ether-ketone? The participants already rehabilitated with dental implants will receive a definitive 3 unit prosthesis incorporating Poly-ether-ehter-ketone.
