摘要:
A face bow and protraction headgear to correct the anterior open bite in dentally Class III open bite cases. The appliance consists of a face bow and forehead pad. The face bow has intraoral and extraoral components custom made individually for each patient. The intraoral bow is inserted from the distal openings of tubes soldered to the extraoral face bow. The extraoral face bow extends backward to the front of the ear then turns upward and ends at the level of the hooks on the forehead pad. Only the forehead is used as anchorage unit. On both sides of the pad, adjustable wire hooks are placed which allow maintaining the distance from the forehead pad hooks to the face bow hooks. Heavy elastics are attached in between the hooks of the face bow and the hooks on the forehead pad.
