Abstract
In individuals with Class II malocclusions, there is an anteroposterior discrepancy between the maxillary and mandibular dentitions, which may or may not be accompanied with a skeletal discrepancy, the most effective treatment option to eliminate is by modified three-piece base arch combined with TADS for simultaneous deep bite correction and en masse retraction.The present case report showcases the treatment results and biomechanics involved for en masse retraction and intrusion of anterior teeth using three-piece intrusion arch and temporary anchorage device.The modified three-piece base arch combined with TADS is effective in controlled translation and intrusion of anteriors and would be a preferable mechanotherapy in low angle case with deep bite, proclined anteriors and Class II malocclusion.
