If it is unilateral there is a deviationof the jaw toward the uninjured side. 306 ORAL PATHOLOGY AND PRACTICE. The reduction of the dislocation is effected by supporting thesymphysis, and at the same time depressing the angles of the jaw,the object being to carry the condyle downward and backwarduntil it will slip over the articular eminence. The operator shouldstand in front of the patient, and, the thumbs being protected bywrapping around them a handkerchief, the jaw is firmly graspedwith both hands, the protected thumbs being placed far back overthe molar teeth. Then, by pressing down with the thumbs andsupporting the symphysis with the ends of the fingers, the jawmay usually be carried to place, the condyle slipping into theglenoid fossa with a distinct snap, and the jaw closing with con-siderable violence. Fig. Dislocation of the Lower Jaw, showing the Anatomical Relation of the Parts. (After Sir A. Cooper.) Sometimes it may be necessary to use a stout piece of woodbetween the back teeth as a lever to carry the condyle down andback, the angle being supported with the hand. This method willbe found especially useful in unilateral luxations. Some kind of apad should always be placed between the teeth of the two jaws, toprevent their being broken with the violence of the closure whenthe reduction is made. Dislocation of the lower jaw backward sometimes occurs, butonly as the result of great violence, and is necessarily accompaniedby fracture of the borders of the fossa. The dislocation in this case:becomes of less importance than the other injury, and its reductionis subordinate to the other treatment.
