What the trial is, and whether it could suit you

This prospective, single-group interventional study will evaluate the stability of periodontal tissues after esthetic periodontal surgery for the correction of altered passive eruption in individuals with excessive gingival display. Ten adult participants with excessive gingival display associated with altered passive eruption and involvement of the alveolar bone will be included. Participants will undergo esthetic crown-lengthening surgery consisting of gingivectomy and osseous recontouring. Periodontal clinical measurements, intraoral digital scans, cone-beam computed tomography, standardized photographs, and patient-reported outcomes will be obtained before surgery and during follow-up. Clinical and three-dimensional tissue changes, esthetic perception, satisfaction, and oral health-related quality of life will be evaluated for up to 12 months after treatment.
