Primary Outcome Measures

Name	Time	Method
The primary endpoint (at visit 4: 15 weeks after implant placement) is to histologically<br>evaluate the height of the biologic width (including sulcus depth, junctional epithelium, connective tissue) around Zirconia and titanium implants.

Secondary Outcome Measures

Name	Time	Method
The following secondary endpoints will be assessed after 1, 3 and 5 years after insertion of the final reconstruction:<br>•Implant survival<br>•Radiographic bone level <br>•Esthetic analysis<br>•Technical complications<br>•Biological complications<br>•Clinical measurements: plaque index, bleeding on probing, probing pocket depth, width of keratinized tissue<br>
