Tipos de intervenções para correção do sorriso gengival: revisão de literatura

Abstract

INTRODUCTION: Facial expressions and smile are key components of non-verbal communication. The smile plays an important role in determining a person's first impression. Excessive gingival exposure is an aesthetic concern for patients. The essential elements of a pleasant smile include lips, teeth and gums. Approximately 10% of the population aged between 20 and 30 years has excessive gum exposure, or gummy smile. This is an alteration that is often a concern for both patients and dentists. PURPOSE: To understand, through a literature review, the aspects involved in the intervention for the correction of gummy smile together with the forms of treatment mentioned in the literature. METHODOLOGY: The methodology consists of an exploratory and descriptive study carried out through a literature review in a period from 1999 to 2021. RESULTS: Gingival smile can be caused by several isolated or associated factors. For each type of cause, there is a specific type of treatment. Vertical maxillary growth, upper lip hyperactivity, hyperplasia and altered passive eruption are some of the possible causes for this condition. CONCLUSION: A correct diagnosis and treatment plan must be correctly directed to the type of etiology involved in the cause of the condition, therefore, it requires a broad theoretical knowledge of the dentist to identify the alteration and choose the intervention.
