Periodontal Tissue Stability After Surgical Correction of Altered Passive Eruption
Sponsor: University of Sao Paulo
Summary
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.

Interventions
Esthetic Crown-Lengthening Surgery
Esthetic periodontal surgery will be performed to correct altered passive eruption. Gingival tissue will be removed by an internal bevel gingivectomy. Osseous recontouring will then be performed to establish an adequate relationship between the cementoenamel junction and the alveolar bone crest. Depending on the periodontal phenotype and anatomical characteristics, osseous recontouring may be performed with or without flap elevation.
