Dental cosmos . th, the appliance isplaced in position, and the bands marked below its line of bands are then removed, and the smaller size platinum wire is SOME METHODS OF REGULATING TEETH. 857 fitted to the marked portion and soldered to form the groove. Theband is then fastened to the tooth with oxyphosphate cement. Ifthe appliance is not well retained, bands may be placed on the bicus-pids or other teeth as needed. If the lateral incisors are to be moved a considerable distance orrequire turning forward, a lug may be soldered to the palatal surfaceof the band, and project back of the central incisor (see Figs. 3 and 4). If all the incisors are to be carried forward, a thin bar may unitethe lateral incisors back of the centrals and thus hold all the incisorsin the same relationship. Similar appliances to those above described may be used for makingroom and forcing prominent lower cuspids into line. In such a casethe wire should follow the curve of the arch back of the lower in- Fig. cisors, passing between the laterals and first bicuspids, forming a loopby curving backward (Fig. 6), and preferably be retained by bands. If posterior teeth are to be moved, additions may be made to theappliance as previously described. It is found in practice that wires interfere less with the voicearticulation when they cross the roof of the mouth by the firstbicuspids, following the curve of the arch, than when they arearranged to pass near the palatal surface of the incisors. Innumerable changes can be made in the arrangements of thesprings for the purposes mentioned. A few of the important onesonly will be stated here. If the arch is not to be spread laterally, or the position of thebicuspids changed, the first wire crossing the arch can be used alonein many cases by employing bands on the lateral incisors and thefirst bicuspids; or two wires may cross the arch, with the ends ofone curved so as to encircle the cuspid, and the wires separated toact as a spring to
