Acceleration of intruding anterior tooth by alveolar corticotomy

True intrusion is one of the difficult and complex goals to achieve which requires clinical judgment, skills, and experience. Intrusion requires less force level than other tooth movement, but it requires delicacy since the entire stress is concentrated in the apex of the root. Although true intrusion alone is not challenging, eliminating the adverse effect while intruding requires tedious skills of the clinician. A 17-year-old male patient with Class I malocclusion with open bite has a prominent maxillary cortical bone. He had a convex profile with an unpleasant smile. To reduce the bulkiness of cortical bone and to intrude the upper anterior, so the decision was made to perform corticotomy.
