Abstract: This case report illustrates the fact that rapid orthodontic tooth movement occurs when selective alveolar decortication is done. This in conjunction with bone graft enhances the bone volume, corrects the fenestrations and bony dehiscence and expands the limits of orthodontic tooth movement. A 24 year-old male patient presented with a Class II Division I malocclusion on a skeletal Class I base with increased bi-maxillary dento-alveolar protrusion with unilateral maxillary posterior cross-bite on the left side. Pre-adjusted edgewise appliance, Roth’s prescription,(0.022 x 0.028 inch slot), was strapped a week prior to the surgical procedure. Full thickness labial and lingual flaps were reflected in the maxillary arch only and the alveolar bone was selectively de-corticated and augmented with an osseograft. Orthodontic treatment was commenced a week post-surgery and adjustments were done fortnightly. The duration of the treatment was about 9 months. The rapid correction of the malocclusion in one-third the treatment time required for conventional orthodontics was as a result of regional acceleratory phenomena triggered by bone activation. The augmentation with the bone graft further enhanced the bone volume required for the expansion of the constricted maxilla without the intervention of any orthopedic device.
