Clinicians have various definitions of
“impaction.” Canine impaction can be
defined as an unerupted tooth after its root
development is complete; or a tooth still
unerupted when the corresponding tooth
on the other side of the arch has been erupted
for at least 6 months and has a complete
root formation; or a condition in which a
tooth is embedded in the alveolus and is
locked in by bone, adjacent teeth, or other
obstacles and cannot properly erupt into
the oral cavity.1-5 This includes teeth in
which eruption is significantly delayed and
there is no clinical or radiographic evidence
that further eruption is likely to happen
