Introduction: The aim of this study was to investigate the positions of
the root apices of palatally impacted canines with cone beam computed tomography. While it
is true that the position of the crown determines the surgical approach and direction of
traction, the location of the apex also plays an important role in orthodontic mechanics.
Methods: Twenty-seven unilateral palatally impacted canines were
evaluated on cone beam images. Measurements were taken using Osirix®
software, in order to compare the location of the apex of the palatally impacted canine
with the apex of the contro-lateral normally erupted canine. Results: The
root apex of a palatally impacted canine was usually correctly positioned in the line of
the arch. Conclusion: In most cases, the orthodontic management of
palatally impacted canines requires little or no root torquing.
