Abstract

The DC60 upper jaw lengthening device consists of a distraction device and a protraction R-bow. The distraction device comprises a cranial frame that can be secured to the patient's head with skull screws. A vertical facial post on the side connects the cranial frame to the horizontal axis. Two sets of traction screws connect the horizontal axis to the traction screws. When the traction screws, which are connected to the protraction R-bow, are tightened, it generates a pulling force on the upper jaw.
