Introduction:

excessive vertical protrusion, vertical overbite, overbite or increased overbite are a frequent finding in maxillomandibular discrepancies.

Objective:

to update knowledge on overbite or excessive vertical overbite in children under 19 years of age.

Methods:

in order to carry out this bibliographic review, 50 articles on the subject were consulted, obtained from Pubmed, LILACS, Hinari, SCielo, academic Google, degree theses and texts of the specialty of Orthodontics. Forty-one articles were used as bibliography, with a predominance of articles published during the last five years and others of earlier date to reference the history of the definition of excessive vertical overbite.

Development:

excessive vertical overbite can manifest in children and adults; it is frequent in class I, II and III malocclusions. Its prevalence increases between five and 12 years of age. The precise identification of these anomalies through clinical and radiographic characteristics is fundamental to achieve a correct diagnosis and timely treatment according to their origin during growth. Orthodontic treatment in these cases aims to conform an adequate vertical protrusion of incisors through the application of various strategies according to etiology, age and facial esthetics. The most severe cases achieve better results when treated during growth and development.

Conclusions:

Deep bite is a common component of malocclusion in children and adults, its etiology should be considered in order to formulate a detailed diagnosis and treatment plan to achieve optimal skeletal, dentoalveolar, occlusal and esthetic results.
