Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the outcome of prosthetic survival of the Acuris conometric concept 1 year after permanent restoration, since this is a new mode of retention using friction for seating the crown of single tooth restorations without using cement or screws.
