IntroductionDental transposition and impaction are disorders related to ectopic eruption or
failure in tooth eruption, which can affect child physical, mental and social
development and may be difficult to be clinically solved. MethodsWe describe a case of transposition between the upper left canine and lateral
incisor associated with impaction of the central incisor on the same side, in a
12-year-old patient. Conservative treatment involving surgical-orthodontic
correction of transposed teeth and traction of the central incisor was conducted.
ConclusionThe option of correcting transposition and orthodontic traction by means of the
segmented arch technique with devices such as cantilever and TMA rectangular wire
loops, although a complex alternative, was proved to be esthetically and
functionally effective.
