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.

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 comfortablebreathing and free movement
