A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . the forces of occlusion wiU slowly move the roots bodily to 350 PART VII. UNCLASSIFIED MALOCCLUSIONS a perfect masticating closure of the crowns; and this is true of every incHnationof molars, unless opposed by stronger forces. It is remarkable, however, how muchmore quickly the correction can be effected by direct intermaxillary elastics attach-ed to hooks on the gingivo-buccal surfaces of the upper and lower molar teeth. SeeDirect Intermaxillary Force, Chapter XVI. It must be remembered, however,that the forces of these elastics in combination with the forces of occlusion, stronglytend toward a lingual movement of the crowns toward their former malpositions,and consequently, their expanded positions dtaring this process must be stronglyretained by lingual or labio-buccal arch-bows. Drop Jack While spring bow expanders are applicable for distal areas, the ideal power for theenlargement of dental arches in every direction will always be the motive force ofa screw. Fig. 249. Fig.
