Conventional force application to the crown may increase the risk of damage to adjacent roots due to insufficient control of root positioning.

Treatment alternatives and biomechanics are discussed to illustrate the effectiveness of this approach.Diagnosis and treatment plan:A boy aged 14 years 1 month presented with a severely angulated impacted maxillary left canine, with the root apex located above the maxillary left second premolar.
