Primary Outcome Measures

Name	Time	Method
Complete root coverage (dichotomous):<br>For this purpose, the preoperative intraoral scan is superimposed with the corresponding intraoral scan after 6, 12, 60 and 120 months using analysis software. If the natural enamel-cement junction cannot be identified after the two scans have been superimposed, the root is considered to be completely covered.
