Lip repositioning with crown lengthening as an alternative to excessive gingival exposure: Clinical case

Abstract

Introduction: excess gummy smile is frequent and appears as a manifestation of intraoral and extraoral etiological factors. Objective: to document the management of a gummy smile associated with lip hypermobility, altered passive eruption and exostoses. Clinical case: 23-year-old female patient with excessive gummy smile. Treatment: surgical lip replacement technique combined with coronary lengthening. Results: 7-month postoperative follow-up with minimal recurrence and the patient reported that she noticed a change in her profile and in the implantation of her nasal wings that was narrower than before surgery. Conclusions: The technique restricts the traction of the levator lip muscle, the depth of the vestibule is shortened, reducing the amount of gingiva that is shown when smiling; the crown lengthening allows to increase the tooth length in the smile.
