A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . afterwards. Fig. 214 was made from a photo-print of the original apparatus moimtedon a set of the finished dental casts. It will be noticed that the power arch-bowwas flattened or ribboned over the incisive area. One of the objects in the exhibition of this and other cases from the earlypractice of the author, is: It will fully disprove the somewhat prevalent assumption 304 PART VI. DENTO-FACIAL MALOCCLUSIONS that the bodily movement of teeth arose with the introduction of the Angle pinand tube appliances of comparatively recent date. It will also show the practicalapplication and common employment of the disto-mesial intermaxillary force,which was first published in connection with the publication of the birth of bodilymovement. Fig. 215 illustrates a case which no doubt started with the premature extractionor natural loss of the deciduous front teeth, followed with the retrvisive malpositionof the erupting incisors to such an extent that the mandible was forced to bite the Fig. lower incisors in front of the uppers to obtain a masticating occlusion of the backteeth. This, in its developing stage caused a lack of development of the incisive orintermaxillary process, impacting the cuspids, and a protrusive malposition ofthe lower front teeth, resulting in a retrusion of the entire upper dento-facial area,and a slight prominence of the lower lip, as seen by the beginning facial cast. Up to the time of the publication of the first edition of this work in 1908,it was the common teaching in certain schools of orthodontia that the theoryof bodily movement of teeth was of no practical value. This was emphasized withthe fantastic claim that when the crowns of the teeth were moved to place, the rootswould soon follow, and the facial outlines would develop to their most harmoniouspossibilities.
