| 摘要 |
One embodiment of the present invention consists of a non-rigid, epigenetic-pneumopedic appliance comprising a wire-type framework supporting bow, bands, brackets or a clasp. The appliance includes active elements adapted to provide brief doses of cyclic forces to induce sutural osteogenesis. The active elements are vibrational, ultrasonic or oscillatory components. The epigenetic-pneumopedic appliance cooperates with an actuator or other expansion mechanism, such as suture spring, that straddles the midline of the appliance. The appliance further includes tooth-contacting material having high-elasticity, such as pre-formed alloys that form 3-D axial springs, which adapt to the long axis of the palatal/lingual surfaces of the teeth. The appliance also includes a plurality of micro-screws 2 along with driving means preferably consisting of either an electrical, ultrasonic (vibrational) meso-motor, or, alternatively, a micro-motor. The epigenetic-pneumopedic appliance may be used with directional bite props. |
