CASE REPORT
Correction of Complete Upper Canine-Premolar Transposition with Palatal Miniscrew Anchorage
Volume 50 : Number 6 : Page 0 : Jun 2016
Transposed teeth, found in .3-.4% of the population, have been attributed to either genetic predisposition or a disturbance of eruption guidance. The maxillary arch is affected more frequently than the mandibular arch; the most common transpositions, in descending order, are canine-first premolar, canine-lateral incisor, canine in the site of the first molar, lateral incisor-central incisor, and canine in the site of the central incisor. In females, who are affected more often than males, transpositions occur more frequently on the left, whereas there is no side predilection in males. Associated dental anomalies include missing teeth, peg-shaped incisors, and supernumerary teeth.
