| Research Abstract |
Osteotomy of alveolar bone with molar roots were carried out in the mandible of Japanese white rabbit. Distraction osteogenesis of alveolus and tooth roots was performed after distractor was put on the mandible. During distraction, mandible of the ultrasound group was treated with low-intensity pulsed ultrasound(LIPUS), and regeneration of cementum and periodontal ligament was observed in the lengthening site. Partial regeneration of dentin and pulp was radiographically observed contrary to our expectations, so that histological observation is attempted now.
