Between 25% and 50% of the general population are affected by impacted teeth,[1] with the incidence of upper-canine impaction reportedly ranging from .92-4.3%.[2-4] Although some cases have iatrogenic or idiopathic origins, potential etiological factors include dentoalveolar discrepancies, transverse maxillary deficiencies, prolonged retention or early loss of deciduous canines, absence or anomalies of upper lateral incisors, abnormal positioning of dental buds, alveoloschisis, and physical obstacles such as supernumerary teeth, mesiodens, odontomas, neoplastic formations, cysts, and root dilacerations.[5-8] Dental impaction has also been correlated with a high incidence of certain syndromes, and palatal canine impaction has been found to run in families.[4-9] Unsurprisingly, therefore, palatal impactions are far more common than labial ones, accounting for 85% of impacted canines.[3,4] The procedures used for surgical exposure and traction are important in any impaction case,[10,11] but a buccally impacted canine is especially problematic. . . .
