Sorriso gengival: etiologia e tratamento - revisão de literatura

Abstract

The aim of this study was to review the literature on the etiological aspects and forms of treatment of gummy smile (GS), which is a term used to define excessive exposure of gingival tissue at the maxillary level. The possible etiologies of GS found in the literature are: altered passive eruption, short or hyperactive upper lip, excessive vertical growth of the maxilla, dentoalveolar extrusion and gingival hyperplasia. One of the main challenges in managing GS is identifying its etiology in such a broad and diverse context. The correct diagnosis is extremely important for an effective treatment plan. Treatment options include facial surgery, oral surgery, laser, botulinum toxin, and hyaluronic acid filler. The treatment is multifactorial and influences not only the aesthetics of the smile, but also the patient's self-esteem.
