Treating hyperdivergent malocclusion accompanied by open bite could be challenging and may be done by several methods as high pull headgear and posterior bite planes or surgically by maxillary impaction in adults. Nowadays it's the skeletal anchorage system (SAS) era as mini-screws and mini-plates ,hence we are aiming for absolute anchorage, and could minimize patient cooperation and the need for surgical treatment.

Lower facial height: the distance between soft tissue subnasale and gnathion (Sn.Gn) the difference will be measured in mm. before and after posterior segment intrusion
This measurement relates principally to the vertical dimensions of the upper dento-alveolar process and the mandible.
