Abstract
A 23-year-old woman with an anterior open bite malocclusion was referred to the clinic. Because she was a skeletal Class II hyperdivergent pattern with retruded mandible, molar intrusion was planned to correct the open bite as an effective strategy. Newly designed modified bonded TPA was applied to intrude the maxillary molars without the excessive vertical change of the incisors which was in normal range. Molars were successfully intruded bilaterally without any buccolingual tilting. The autorotation of the mandible was accompanied with molar intrusion, which contributed to the improvement of facial esthetics.
