Dental cosmos . to use platinum wire splice anchoredto plates and to clamp-bands, or a piece of plate soldered to properanchors and dipping down between the instanding teeth and the gum. Several of the devices I have, long ago, published in the DentalCosmos, but probably the most efficient class of mechanisms thatwould be thought superior has yet to be made public. SPUR PLATES FOR REGULATING TEETH. 673 Some of them I will here draw upon the blackboard ; taking,first, the case of an instanding upper cuspid. (See Fig. 1.) Vulcanized into and projecting from the palatine surface of thehard-rubber roof-plate, having a clamp-band on each side for anchor-ing to some of the side teeth (here represented to be the bicuspids),is a piece of gold plate, P, about one-eighth of an inch wide. Thisextends beneath the gums surface and bears upon the lingual sideof the neck of the cuspid. To give a strong anchorage to this pieceof gold plate, it is bent at a right angle, as shown in the lower part Fig. 1. Spur of the diagram. Thus a foot is shaped which becomes imbedded in aconsiderable portion of the substance of the roof-plate. To operate this device and maintain pressure upon the tooth, thisspur is bent more and more every two or three days. When it hasbeen bent so far as to lessen or lose its utility, it is taken off, and itsoriginal form set forward and vulcanized to the plate. Then theprocess is renewed and steadily progresses until the cuspid has been Fio. 2. Section of Spur Plate.
