Outline of Final Research Achievements

From the result of this study, we revealed the optimal conditions for effective and efficient supplemental vibration for accelerating tooth movement. Optimum-magnitude high-frequency vibration applied with static continuous force does not affect root resorption and induces NF-κB activation in osteoclasts, osteoblasts and osteocytes and increases periodontal ligament volume via osteoclastic bone resorption and promotes bone resorption in deep alveolar bone during tooth movement. These findings contribute to a better understanding of the mechanism by which optimum-magnitude high-frequency vibration accelerates tooth movement, and may lead to novel approaches for the safe and effective treatment of malocclusion.
