A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . Fig. involving two or three teeth on each side, and a drop jack, or even a straight jackmay be made to rest firmly in position upon the lingual bars that are soldered tothe root-wise extensions. Or the extensions may be bent and fitted before solderingto form the bars upon which the jack rests. V-shaped arches, similar to that shown in Fig. 251, may be expanded, and the in-cisors brought to normal arch alignment with an expanding jack No. 14, resting uponan annealed, or semi-hard lingual bow, No. 18, attached as shown by the will be seen that the lateral expansion of the bow in a line with the cuspids, willretract and enlarge its anterior curve, and—if the anchorages are stationary—will retrude the front teeth to the full extent of this movement. If the contractionof the arch is not symmetrical—one side being contruded slightly more than theother—the bow may be annealed at the point of greatest contrusion, and this willenable it to more readily bend outward under the str
