Early orthodontic treatment of unilateral mandibular left lateral incisor–canine transposition: A Case Report

ABSTRACT

Among dental anomalies, tooth transposition is considered the most difficult to manage clinically. Distal migration of permanent mandibular lateral incisor happens rarely. It can be discovered radiographically in the early mixed dentition & interceptive treatment is often appropriate. If left uncorrected it may erupt ectopically and the results are often unsatisfactory both esthetically and functionally. When transpositions are detected early the positions of the root apices are important in deciding where to move the transposed tooth. This article reports a case of early orthodontic treatment of a rare unilateral mandibular left lateral incisor – canine transposition.
