- Primary Outcome Measures
Name Time Method Tissue volume changes in horizontal dimensions between baseline (before implant placement) and at 4 month post implant placement. The changes will be evaluated based on scans of the impressions.
- Secondary Outcome Measures
Name Time Method Secondary endpoints will be assessed 3 years after Crown insertion (Baseline 2):<br>- Buccal tissue changes <br>- Margo mucosae level: using a periodontal probe<br>- Clinical measurements: KT (width of keratinized tissue), PD (pocket depth), REC (recession), BOP (bleeding on probing), Pl (plaque index) <br>- Relative contour increase: using CBCT scans<br>- Patient related outcome measures (PROMs): using questionnaires
