Study Notes

Canine Impaction Prevalence

Maxillary canine impactions are relatively common, affecting around 1-2% of the general population.
Labial impactions are the most common type, with the canine being positioned outside the normal eruption path, in the direction of the lips.
The guidance theory suggests that the canine erupts along a predetermined pathway guided by its follicle and surrounding tissues.
This pathway can be disrupted by various factors, leading to impaction.
Orthodontic offices typically see a significantly higher incidence of impacted canines, with estimates reaching up to 20%.
This difference highlights the importance of early orthodontic intervention in managing these cases.
Labial impactions are frequently associated with crowded dentition, which can physically obstruct the canine’s eruption path.
Mandibular canine impactions occur less frequently than maxillary canines.
