Effect of Abutment Configuration on Peri-implant Soft and Hard Tissue in the Esthetic Zone - Randomized Clinical Trial

Effect of Abutment 3-dimensional Configuration on Peri-implant Soft and Hard Tissue in the Esthetic Zone - Randomized Clinical Trial

Sponsor

Semmelweis University

Enrollment

30 participants

Start Date

Dec 13, 2023

Study Type

INTERVENTIONAL

Conditions

Dental Implants, Single-ToothDental Implant-Abutment Design

Summary

The aims of our study are to investigate in patients with immediate implantation replacing a single tooth in the maxillary anterior (#FDI 15-25) region the effect of (a) custom vs cylindrical stock healing abutments, then (b) screw retained single ceramic crowns, on the peri implant hard- and soft-tissue formation and blood flow.
