Palatally impacted canine: diagnosis and treatment options

Dental impaction is a condition in which tooth cannot erupt because it may be retained by either adjacent bone or tooth. Following the third molars, upper canines are among the most frequently impacted teeth, with prevalence ranging from 1% to 3%. Therefore, impacted canines are defined as being those teeth not erupted within 6 months of their complete root formation or when they are not present in the arch during the eruption phase. Impacted upper canines are found in approximately 2.0% of the general population, occurring more than twice as frequently in women (1.17%) as in men (0.51) and moving more palatally (60-80%) than unilaterally (75-95%).

Impacted teeth are particularly more difficult to treat in adults. Success rate among patients older than 30 years was 41%, whereas patients aged 20-30 years old achieved 100% success.
