Abstract Synopsis

”IMPACTION OF MAXILLARY CANINES: DIAGNOSIS, PREVENTION
AND TREATMENT PROTOCOLS ”

Apostolos I. Tsolakis, Associate Professor of Orthodontics
National and Kapodistrian University of Athens , Greece.

ABSTRACT

Maxillary canines are the second more frequent impacted teeth, after the third molars
presenting a prevalence of impaction ranging from 1% to 3%.
A radiographic evaluation is always necessary in order to confirm the canine
impaction. The sensitivity of CBCT compared to the conventional x-rays is much
higher allowing more precise diagnosis of the location, the detection of possible root
resorption in adjacent lateral and /or central incisors due to canine impaction, as well
as treatment decisions.
Prevention is primarily followed during mixed dentition period, including expansion
and distal movement of the dental arch. Also extraction of the primary canines in
selective cases may be helpful. Whenever prevention strategy of impacted maxillary
canines fails, the conventional treatment consists of combined surgical and
orthodontic traction approach.
There is a debate among clinicians whether the open or the closed surgical exposure is
the favorable treatment of choice for palatally impacted canines. There is some
evidence that there is no difference between the two techniques in terms of
periodontal health, and that the open exposure technique constitutes a shorter surgical
procedure.
Following the surgical exposure, an orthodontic button is bonded on the crown and a
wire chain is fixed on the button. Orthodontic traction is applied to the impacted
canine and the force is directed according to the site and direction of impaction, taken
care of possible resorptions of the adjacent teeth. Many biomechanical strategies have
been proposed with the aim to avoid possible side effects. Whenever the impacted
canine erupts in the alveolar ridge any rotations and /or torque movements are
considered. A number of clinical cases and various treatment protocols are presented.
