Sectional-type differential vibrating biteplate and sectional-type differential dentognathic orthopedic device

The invention relates to the field of dentognathic orthopedic techniques, and provides a sectional-type differential vibrating biteplate and a sectional-type differential dentognathic orthopedic device. Such a sectional-type differential vibrating biteplate comprises an anterior tooth vibrating unit, a left posterior tooth vibrating unit and a right posterior tooth vibrating unit, wherein the anterior tooth vibrating unit is corresponding to the position of an anterior tooth; the left posterior tooth vibrating unit is corresponding to the position of a left posterior tooth; the right posterior vibrating unit is corresponding to the position of a right posterior tooth; independent vibrating mechanisms are mounted in the anterior tooth vibrating unit, the left posterior tooth vibrating unit and the right posterior tooth vibrating unit respectively; elastic connecting units used for weakening vibration transmission are connected both between the anterior tooth vibrating unit and the left posterior tooth vibrating unit and between the anterior tooth vibrating unit and the right posterior tooth vibrating unit. The sectional-type differential dentognathic orthopedic device comprises the sectional-type differential vibrating biteplate and an extra-oral machine. The three vibrating units of the sectional-type differential biteplate can independently generate vibration; therefore, the directional vibration can be applied to a tooth; the movement of a local tooth is promoted; the personalized movement of the tooth at a specific segment is carried out.
