The results indicate that PEMF combined with biomechanical force could accelerate the rate and amount of orthodontic tooth movement, enhance bone deposition in tension side and resorption in compression side. The results also suggest that PEMF could accelerate orthodontic tooth movement as a result of increase in quantity of active cells, PEMF couldn’t change the ultrastructure of cells.展开更多
