[Establishment of a dog model of orthodontic tooth moving into newly distracted bone].

Purpose: This study was to establish an animal model of tooth moving into newly distracted bone after mandibular distraction osteogenesis in Beagle dog.

Methods: Eight Beagle dogs were selected in this study four dogs (experiment group) underwent 10 mm of bilateral mandibular distraction osteogenesis. After 0-week consolidation periods, the bilateral third premolars were moved distally into the regenerated bone with 150g orthodontic force for 8 weeks.
