A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . d the molar teeth is ideal. Some orthodontists speak of moving the teeth inward, outward, forward,or backward, as though they were dealing with plain porcelain teeth set up inwax on a mechanical articulator, without taking into consideration the anatomy,physiology, or pathological conditions presented in the jaws or the general system. The writer can readily understand how teeth can be moved forward, as arule, by orthodontists, as that is the direction of their general or usual movementduring development or eruption into their proper positions. But he doubts theability of any man to successfully move a lower first molar backward half its width CHAPTER X. TYPICAL AND ATYPICAL OCCLUSION OF THE TEETH 71 when theother molars are in position. It may be possible — though it is some-what doubtful — for the lower first molar to be moved half its width backward inthe mouth of a child about seven or eight years of age, but your essayist fears seriousresults even in such a case. Fig. 1(>.. Side view of the upper and lower jaws of a child about seven oreight years of age. showing the deciduous teeth, the firstmolars, and the germs of other permanent teeth. Fig. 16 is from a specimen of jaws belonging to a child seven or eight yearsold. We find all the deciduous teeth in position, also the first molar. The de-veloping crown of the second molar is just posterior to it. The germ of the thirdmolar is not shown. Suppose it were possible to move the first molar backward Fig. 17.
