简要总结
Compare between bi-maxillary (maxillary and mandibular) posterior dento-alveolar intrusion and maxillary posterior dento-alveolar intrusion as regards open bite closure.
详细描述
Now, maxillary posterior dento-alveolar intrusion has been validated as a conservative treatment modality for treatment of skeletal open bite in adult patients. However, it was proved that mandibular posterior teeth extrusion take place during the treatment which results in reduction in the amount of open. bite closure. Therefore, the aim of our study is to compare in a randomized clinical trial methodology between maxillary posterior dento-alveolar intrusion and combined maxillary and mandibular posterior dento-alveolar intrusion in terms of anterior open bite closure.
