Dento-Alveolar distraction osteogenesis using rigid intra-oral tooth borne distraction device

Background: The aim of this clinical prospective study is to apply and evaluate an approach to reduce the overall orthodontic treatment time, by means of dentoalveolar distraction osteogenesis to achieve rapid canine retraction using an indigenously developed intra-oral tooth-borne distraction device. Materials & Methods: This study was carried out in the Department of Orthodontics and Dentofacial Orthopedics. Four patients selected for the purpose of Maxillary and/or Mandibular canine distraction with a rigid custom-made, intra-oral distraction device made of stainless steel and were scheduled for orthodontic treatment with bilateral first premolar extraction and then subsequent bilateral canine teeth distalization. Results: In all the patients the canine teeth moved distally and made contact with the second premolars within 14-16 days range after which they were kept passive, with the appliance for a week of consolidation. The amount of canine retraction was in 7-7.5mms range, in all the patients, in each of the four quadrants studied. Bodily movement, tipping and buccal flaring of the canine teeth were noticed in all the cases. Conclusion: Combination of newer orthodontic appliances and the principles of biomechanics to maintain the control over rapid tooth movement, rapid canine distalization using distraction osteogenesis awaits further development before routine application, of this innovative and exciting approach.
