Abstract
- Tooth movement facilitated by corticotomy and distraction osteogenesis, a new paradigm in orthodontics, was discussed. Molar uprighting was thought to be either difficult or nearly impossible. In this study, a section of cortical bone, which may act as resistance to tooth movement in alveolar bone, was removed. Active bone deposition was also made possible in the tension side. This forms the main concept of tooth movement facilitated by corticotomy and distraction osteogenesis. Molars in two cases were uprighted at such a speedy rate as we could not imagine in conventional tooth movement, which lead to reduction of the total treatment period. And molar uprighting was possible without side effects, for example, supraversion of the tooth or anterior anchorage loss. These were the superior aspects to conventional orthodontics.
