Correção de sorriso gengival com a técnica da gengivectomia e uso da toxina botulínica: Um relato de caso

Abstract

The smile reflects an individual's internal feelings and also influences their socialization aspects. A gummy smile is characterized by excessive exposure of the gums when smiling, impacting the patient's appearance and self-esteem. It presents itself in dental clinics as one of the main aesthetic complaints. This condition can have isolated or associated causes, with this etiology revolving around the vertical excess of the maxilla, hypermobility of the upper lip elevator muscles, altered passive eruption and superior dentoalveolar protrusion. Your treatment must be planned according to the cause/causes and there are several approaches. Some are more traumatic and long-lasting, such as orthognathic surgery and orthodontic movements, and others are less invasive, such as periodontal procedures and the use of botulinum toxin. This work aimed to present a clinical case of correction of excessive gummy smile due to excessive vertical growth of the maxilla, hypermobility of the upper lip elevator muscles and altered passive eruption. The first stage was surgical, gingivoplasty techniques, gingivectomy with osteotomy, gingival melanic depigmentation and, subsequently, the non-surgical stage with the application of botulinum toxin. Satisfactory aesthetic results were observed for the patient, improving not only the excessive gum exposure when smiling but also her self-esteem in general. Furthermore, it was evident that, with a correct diagnosis and the use of appropriate techniques, the final outcome of the case was successful.
