Abstract: Bimaxillary protrusion is a condition warranting retraction of upper and lower incisor for optimizing their axial inclination to obtain lip competency and for straightening the profile. These cases generally require maximum conservation of anchorage since the entire retraction space must be utilized for retracting the incisors with protracted treatment time. Demineralization of a thin layer of bone over a root prominence after corticotomy surgery can optimize the response to applied orthodontic forces. The current technique employed a modified stage of corticotomy procedure which utilizes the principle of Regional acceleratory phenomenon, in addition Demineralized freeze dried bone was also used to augment the periodontal apparatus. The current modification is relatively simple, less invasive and can be done under local anesthesia as an outpatient procedure. The results conclusively prove that selective alveolar decortication is effective for retraction, reduces the retraction time by half in addition to conserving anchorage.
