Abstract

Upper and lower cuspids are very important teeth in point of function as well as esthetic. However, failure of eruption of the canine sometimes happens and is frequently encountered clinical problems. Upper cuspids are more frequently impacted as compared with lower cuspis and palatally impaction is more frequent event than labially impaction. Impaction of the mandibular canine is unusual event, especially crossing the midline (transmigration) is very rare. Because of, in most cases, there is no signs and symptoms, impacted teeth can be detected by periodic radiograph examination. The etiology of impaction is unclear and multifactorial. The treatment of impacted canine is influenced by presence of obstacles, location and direction of impaction, space for alignment and development of root. There are several treatment options; (1) Surgical removal and/or observation, (2) Window opening and orthodontic traction, (3) Autotransplantation. The first patient (impaction of upper right cuspid) is treated with window opening and orthodontic traction. The second patient (bilaterally impaction of lower cuspids) is treated with autotransplantation, because of transmigration.
