The Dental cosmos . plan is adopted, and it is nearly impossible in those cases in which allthe teeth were lost prior to the accident, for it is a well-known factthat as a rule edentulous jaws do not come in contact, and if theyshould, a normal occlusion would not be obtained, nor the injured FRACTURE AND DIASTASIS OF THE SUPERIOR MAXILLAE, ETC. 183 parts prevented from slipping out of position. The plan of treatmentadopted by Professor Johnston is also objectionable by reason of thewounds made in the cheeks. In my cases I was compelled to devisesome other means, one which would maintain the position of thefractured bone and at the same time leave the lower jaw free, so thatthe mouth could be open for the purpose of breathing. This wasaccomplished by adapting the principle of the Kingsley interdentalsplint to the upper jaw and supporting it from the cranium. Im-pressions of the upper and lower teeth were taken in modeling com-pound, by first molding it on the upper teeth, and while it was yet Fig. i soft forcing the lower jaw upward till a correct occlusion of the teethwas obtained. This impression was trimmed to the desired shape,and a one-eighth inch steel wire was imbedded in the sides upon a linewith the ends of the teeth and then bent backward upon itself oppo-site the cuspids, and allowed to extend outside the cheek nearly to thelower border of the ear. From this was constructed a hard rubbersplint with the wires attached. The splint can be made from silverswaged over metal dies ; but if a metal plate is desired, the most per-fect adaptation can be secured by the electro-deposit plate and thewires be attached with solder. The splint is held in position by meansof double elastic straps attached to the wire upon each side andbuckled to a close-fitting leather or net cap, reinforced with leather THE DENTAL COSMOS. laced firmly upon the head. This appliance proved very successful,as it held the bones in their proper position, and permitted comfortablebreathi
