This article demonstrates a new orthodontic method that provides shortened treatment times and concomitant periodontal alveolar augmentation. A female patient, 27 years of age, with a Class I, moderately crowded malocclusion, elected to undergo this new treatment option, due to the estimated reduction in treatment time. During the week following bracketing and wire activation, labial and lingual full-thickness flaps were reflected in the maxillary and mandibular arches. The exposed cortical layer of bone over the roots of the teeth designated for the major orthodontic movements was then selectively decorticated. Prior to the primary flap closure, a bone grafting/augmentation procedure was performed over the partially decorticated bone. Following the periodontal plastic surgery, the orthodontic adjustments were performed approximately every 2 weeks. No excessive forces were used. The total orthodontic treatment, from bracketing to debracketing, required exactly 6 months, with 12 orthodontic adjustments. The authors theorize that the rapid orthodontic decrowding and minimal apical root resorption are attributable to increased regional bone turnover (the regional acceleratory phenomenon) and the associated osteopenia (ie, calcium depletion and diminished bone density) that was precipitated by selective decortication.
