Clinical Trial for Printed Implant Resin Crowns

NCT07113509 | Completed

• 1 other identifier: 07.06.2022-No: 22-5.1/57
• Study Type: interventional
• Target: 30
• Locations: 1 country
• Sites: 1

Brief Summary

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

Conditions

Surface Finish; Wear

Keywords
