NCT05589532

Brief Summary

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