ABSTRACT:
Disclosed is a method and apparatus for electrically stimulating bone growth and tooth movement in the mouths of mammals. A positive electrode is placed on the gum surface adjacent the bone structure which is to be resorbed. A negative electrode is placed on the gum surface adjacent the bone tissue which is to be accreted or built up. A current source is connected, such that a small current flows between the electrodes, which has the effect of stimulating bone growth in a specific direction. In a preferred embodiment, the electrodes are placed on the gum surface adjacent a tooth, the positive electrode on the side towards which the tooth should move, and the negative on the side from which the tooth will move. Application of a small current to the electrodes will enhance the repositioning of the tooth in conjuction with normal orthodontic practices.
