DENTO-FACIAL MALOCCLUSIONS lower. In those cases where the lower denture and chin are carried far to one sideby the lateral bending of the mandible, there is very little hope, after twelve yearsof age, of accomplishing anything toward a restoring movement of the mandible,or in other words, a permanent movement of the chin toward the median a stuprising dental and facial correction will always ensue by moving the frontteeth of one denture to the right and the other to the left toward their normal Fig. occluding relations, thus harmonizing the immediate relations of the dental andfacial Hnes. This is well illustrated in the following case. If the lower denture is protruded, as commonly obtains in these cases, a firstlower premolar may be extracted on the protruded side, and the forces applied soas to carry all the front teeth and opposite premolars over to that side mesio-distaUy and lingually, to close the space.
