Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoint (at visit 4: 15 weeks after implant placement) is to histologically evaluate the height of the biologic width (including sulcus depth, junctional epithelium, connective tissue) around Zirconia and titanium implants. | — |
Secondary
| Measure | Time frame |
|---|---|
| The following secondary endpoints will be assessed after 1, 3 and 5 years after insertion of the final reconstruction: • Implant survival • Radiographic bone level • Esthetic analysis • Technical complications • Biological complications • Clinical measurements: plaque index, bleeding on probing, probing pocket depth, width of keratinized tissue | — |
