Implant Supported Single Crowns With Different Retention Modes - Effects on Peri-implant Tissue: A Prospective Randomized Controlled Clinical Trial

Medical University of Graz·interventional·Posted Jan 13, 2021·Updated Jan 27, 2026

In Brief

A clinical study evaluating conometric concept Acuris system, screw retention, and 1 other intervention for Complications: Inflammatory Reactions, Mechanical Complications. Completed, enrolled 39 participants across 1 site.

Detailed Summary

This study aims to examine the inflammatory response mediated by MMP-8 (Matrix metalloproteinase-8 ) level in peri-implant sulcus fluid adjacent to screw-retained, cemented or using the Acuris-system fixed single implant crowns as well as changing of the marginal bone level within the first year after implant restoration. Furthermore periodontal parameters, patient satisfaction and possible occurring biological or technical complications will be evaluated.
