Study & Design
- Study Type
- interventional
- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method The primary outcome is the stability of the buccal margo mucosae six months after insertion of the final reconstruction. It is evaluated by measuring the difference of the clinical crown length at baseline and six months later (recession).<br>
- Secondary Outcome Measures
Name Time Method Secondary outcome variables include the clinical feasibility, investments in time and costs for all three treatment modalities and esthetic outcomes (Photos, Papilla-index).<br>These parameters will be assessed 1, 3 and 5 years after final reconstruction.<br>
