The correction of the maxillary or bimaxillary dentoalveolar protrusion by en-masse retraction of the upper anterior teeth with/without acceleration is accompanied by aesthetic results in the facial soft tissues as well as in the underlying skeletal and dental structures. The traditional corticotomy-assisted retraction is expected to reduce the retraction time significantly. However, the strength of evidence is not strong and requires additional research work.
