Gummy smile correction with esthetic crown-lengthening surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective, single-arm study will perform esthetic crown-lengthening surgery (gingivectomy with osseous recontouring) on 10 adults with altered passive eruption and excessive gingival display. Participants will be followed for 12 months with clinical measurements, 3D intraoral scans, cone-beam CT, photographs, and patient-reported outcomes to assess tissue stability, esthetic perception, satisfaction, and oral health-related quality of life. The study is non-randomized and before-and-after in design, focusing on the relationship between gingival margins, tooth length, and bone crest after procedure. Data will characterize three-dimensional tissue changes and patient perspectives over time.
