Abstract(s)
A agenesia dos incisivos laterais superiores (MLIA) é uma anomalia congenita que surge com relativa frequência na prática ortodôntica e afeta a estética do sorriso. Pode gerar um diastema entre os incisivos centrais, espaçamento anterior, migração mesial de caninos, desvio da linha média no caso de agenesia unilateral, má oclusão e falta de crescimento alveolar. O tratamento deve ser multidisciplinar, no qual a ortodontia apresenta um papel de destaque na decisão de abrir, manter ou fechar o espaço do incisivo lateral superior. Na falta de consenso, o objetivo deste trabalho é elucidar as abordagens ortodônticas, suas indicações e apresentar alguns casos clínicos que usaram a ortodontia como parte da interdisciplinaridade necessária para o tratamento. Concluiu-se que o fechamento de espaço e reanatomização dos caninos parece ser o preferido quando possível, uma vez que a reabilitação protésica com implantes e próteses ainda apresentam desvantagens estéticas detetáveis com o passar dos anos.
Upper lateral incisor agenesis (MLIA) is a congenital anomaly that arises relatively frequently in orthodontic practice and affects smile aesthetics. It may generate a diastema between the central incisors, anterior spacing, canine mesial migration, midline deviation in the case of unilateral agenesis, malocclusion and lack of alveolar growth. Treatment should be multidisciplinary, where orthodontics plays a prominent role in the decision to open, maintain or close the upper lateral incisor space. In the absence of a consensus, the aim of this paper is to elucidate orthodontic approaches, their indications and to present some clinical cases that used orthodontics as part of the interdisciplinarity required for treatment. It was concluded that canine space closure and reanatomization seems to be preferred when possible, since prosthetic rehabilitation with implants and prostheses still has detectable aesthetic disadvantages over the years.
