A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . 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

BASIC PRINCIPLES OF PRACTICE half its width, would it not interfere very materially with the second molar bydisturbing its true position—by carrying it backward and turning it over to agreater or less extent? Fig. 17 is from a similar preparation, of a child about twelve or thirteenyears of age. If the first molar had been moved backward half its width, atthe age of seven or eight years, the second molar would have been carried backwith it. This would not have allowed proper space for the third molar, whichwould more than likely have become impacted. Fig. 18.
