Thin metal is fitted to the labial surfaces of the teeth to be moved, being made to extend well towards the necks and distal surfaces of the teeth. A good- sized spring wire is then formed to fol- low the outline of the anterior teeth on their labial surfaces and extend to the metal clasps, to which it is soldered. Moving Bicuspids Inward. (Jackson.) The appliance should be removed from time to time and the clasping ends of the spring bent toward each other to exert the pressure required. A simple wire fixture, by the same writer, for moving either outward or inward a single bi- cuspid is shown in Fig. 101. A spring wire is bent in the form of a crib surrounding the misplaced tooth and an adjoining one on each side, pass- ing well up toward the gum on the labial and lingual sides, with the ends of the spring wire terminating and overlapping upon the tooth to be moved. simple wire Spnng (Jackson.)
