ABSTRACT:
Fracture reduction and intermaxillary fixation are performed with a dental splint that is directly bonded by cement to the teeth of a patient for temporarily fixing and immobilizing the patient's jaws during and following oral surgery. The splint includes an arch band having a back side surface for receiving a deposit of bonding cement and a facial side surface from which multiple ligature studs project for engaging ligature wires. Each stud includes a tapered shank portion and a symmetrical head portion. The head portion of each stud is conformed for pivotal coupling engagement with a forceps tool. The arch band is intersected by multiple flow passages that permit bonding cement deposited on the back side surface of the arch band to flow or extrude onto the facial side surface as the arch band is pressed against the patient's teeth. Symmetrical construction of the head portions allows universal coupling engagement and manipulation by installation and de-bonding tools.
