Corticotomy-assisted adult rapid maxillary arch expansion and ridge augmentation: An interdisciplinary case report with 7-year follow-up.

Adult orthodontic treatment involving maxillary transverse deficiency is a challenge for an interdisciplinary team. Surgically assisted rapid palatal expansion to segment the maxilla was once the treatment of choice, but the invasiveness, bone deficiency, and gingival recession hindered its acceptance. Corticotomy-assisted rapid maxillary arch expansion with ridge augmentation has the advantage of augmenting alveolar bony housing to accommodate and facilitate tooth movement.

Achieving ideal results when treating a difficult malocclusion is a challenge that orthodontists frequently encounter. Maintaining those results is sometimes more challenging than the correction itself. As specialists in orthodontics, we should be able to apply bone physiology concepts during the diagnosis and treatment planning process and predict how bone will react after biomechanical stimuli.
