| Research Abstract |
Problems on orthodontics were considered as taking long time to move teeth, because it is necessary to behave tissue remodeling as bone resorption and apposition during tooth movement. The aim of this study was to achieve effective tooth movement. At first we have developed a new Equipment to produce micro tooth movement. Then intermittent irradiation of the high Power Semiconductor laser could have possibility to heal degenerated tissue faster.
