Material and methods
The experimental animals were 12 male adult beagles. They were caged individually with regulated light and temperature, and fed soft dog food and water to prevent any damage to the experimental orthodontic appliance. All experimental procedures were performed under intravenous anesthesia with sodium pentobarbital (25-30 mg per kilogram of body weight). The experimental conditions and procedures were approved by the Animal Ethics Committee of Miyazaki University.

Results
The distances of the tooth movement on the experimental side were significantly greater than those on the sham sides at T1, T2, and T4 (Fig 5), approximately double those on the sham side. Tooth movement increased almost linearly from T0 to T4 on the experimental side. On the sham sides, tooth movement stopped from T1 to T2, but the distances increased from T0 to T1 and from T2 to T4.
The movement velocity on the experimental side was also faster than that on the sham side throughout the
Discussion
The average distance of tooth movement by an orthodontic force of 0.5 N on the sham side in this study was 1 mm in 4 weeks, and this value is similar to that in a previous dog study.16 The distance was approximately double on the experimental side at T1, T2, and T4 compared with the sham side. Moreover, tooth movement velocity on the experimental side was significantly faster than on the sham side at T0-1 and T1-2: 2 and 5 times faster on the experimental side, respectively. Therefore, it is
Conclusions
The alveolar corticotomy procedure increases orthodontic tooth movement for at least 2 weeks after the corticotomy and decreases the risk of root resorption. This process might be brought about by the rapid alveolar bone reaction in the bone marrow cavities, leading to less hyalinization of the PDL on the alveolar wall.
