For example, the jaw may be too small to fit the wisdom teeth. Kuftinec [12, 13] asserts that if the canines cusp is mesially at the root of the lateral incisor, the impaction is probably palatal but if the cuspid is found overlapping the distal half, a labial impaction is more probable. At the age of 11, only 5% of the population has non-palpable or non-erupted canines unilaterally or bilaterally. The risk of damaging adjacent teeth is also higher with teeth in an intermediate position. Most big websites do this too in order to improve your user experience.

Surgically exposing the crown of the canine may allow it to come into position by normal eruptive forces. There was a significant difference between all the groups except between group 3 and 4 [11]. Unresolved: Release in which this issue/RFE will be addressed. Springer, Singapore. In cases of unilateral impaction, instead of extending the incision to the contralateral side, a vertical incision may be given in the mid palatal region.
