Clinical Trial for Printed Implant Resin Crowns

The goal of this clinical trial is to assess the clinical performance of printed resinous implant crowns with two surface finishing protocols-mechanical polishing versus glazing. Qualitative performance will be checked by scoring systems.

The main questions it aims to answer are;

* Do printed resin implant crowns clinically succeed in the sort-term? * Do mechanical polishing or glazing the crowns would be better for clinical performance?

Participants will:

* receive either mechanically polished or glazed printed resin implant crowns, * visit at 6-months and 1 year for clinical check
