Angle Class I malocclusion treated with extraction of first permanent molars

Ivan Tadeu Pinheiro da SILVA

Angle Class I malocclusion is characterized by normal anteroposterior molar relationship, which may or may not be accompanied by skeletal changes—in the vertical or transverse planes—or dental changes. Bimaxillary dental protrusion, characterized by pronounced labial inclination of maxillary and mandibular incisors combined with excessive overjet, expose patients to dental trauma and compromise aesthetics. In deciding which teeth to extract for Class I correction the first or second premolars are usually selected due to their location in the dental arch. However, the extraction of a first permanent molar compromised by caries or extensive restoration may be an alternative that ensures the preservation of a healthy tooth instead of one that has already been manipulated. This case, treated in an unusual manner by the extraction of four first permanent molars, was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO) as representative of category 2, as part of the requirements for obtaining the BBO diplomate title.
