- Primary Outcome Measures
Name Time Method oss of volume between pre-extraction and 8 weeks based on volumetric measurements (by superimposition of the scanned models).
- Secondary Outcome Measures
Name Time Method • clinical condition of soft tissues at 8 weeks<br>• The height of the oral and buccal aspect of the alveole will be measured clinically (at Visit 5). <br>• Thickness of the buccal bone crest, bony horizontal ridge width and dimensional changes are evaluated by CBCT scans (Between extraction and 6 weeks). <br>• A histologic assessment at the implant site will be performed at implant placement (at Visit 5). <br>• Ridge width will be analysed (at Visit 5).<br>• Volumetric changes of soft<br>and hard tissues, peri-implant health as well as implant survival up to five years after crown insertion
