A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . it is this particular Type in which this method of force has seemed to be especiallyapplicable. See Fig. 127, Chapter XXI. The surprising possibility of a reciprocal disto-mesial shifting of the buccalteeth to a normal occlusion was the one thing which caused the Angle school oforthodontists to believe—as many of them still believe today—that all casesbelonging to Class II malocclusions should be treated in this manner. Fig. When the dentures have been shifted to a normal occlusion in this way withthe intermaxillary force, notwithstanding the so-called locking force of normalocclusion, they are usually very difficult if not impossible to retain. First, becausethis character of malocclusion no doubt arises from a strongly marked hereditarytype, or the admixture of inharmonious types, and second, because retention can CHAPTER XXXI. TYPE A. DIVISION 1. CLASS II. 251 only be accomplished by the employment of the same intermaxillary forces thatwere employed in correction. The difficulty of moderating this force to the exactdegree required for retention, and the need of having the patient attend to the ad-justments presents difficulties that at times are insurmountable. This is true, moreover, in this method of correcting all disto-mesial malocclu-sions of the buccal teeth which arise from heredity. If the buccal teeth, throughthe strong forces of heredity, have assumed that position in relation to the bonesin
