Design outcomes
Primary
| Measure | Time frame |
|---|---|
| - Implant loss within an observation period of five years after insertion, differentiated according to the two implant materials. | — |
Secondary
| Measure | Time frame |
|---|---|
| - Occurrence of biological and technical complications (material-dependent) - Bone remodeling (radiologically determined using standardized x-rays) - Pink Esthetic Score (PES) - Patient satisfaction (Patient-Reported Outcome Measures, PROMs) - Pain perception in the first week after implant placement (visual analog scale, VAS) - Differences in clinical parameters: o Bleeding on probing (BOP) o Probing depths / attachment level (ATL) o Papilla index according to Jemt o Modified plaque index according to Mombelli - Concentration of the inflammatory marker a-MMP-8 in the peri-implant sulcus fluid - Primary and secondary implant stability (measured using resonance frequency analysis and determination of ISQ values at the time of insertion and before prosthetic restoration) - Accuracy of implant position with navigated insertion - Clinical results of zirconia hybrid abutment crowns in terms of survival rate and technical complications. | — |
