A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . are now shown on each side of theradiogram. Cast C shows the incisor in a partial state of natural eruption afterthe obstructions were removed. At this time band appliances were attached forthe regulation, with the final result shown by cast D. Fig. 281 shows casts, etc., of a boy of seventeen years. Cast A and radio-gram on the left show dental arch and location of the impacted incisor. Bycarefully observing the radiogram, the shadow of a small dense body is seen to lieat the incisal edge of the impacted tooth in the pathway of its natural proved to be an odontomata about half the size of an incisor crown which was CHAPTER LI. IMPACTIONS 373 loosely imbedded in a partially absorbed area of the process. Having no powerof its own to erupt, and composed of a structure that resisted the resorptive elementsit remained as a permanent obstruction in the pathway of the natural growthof the impacted incisor. Upon examining it after its removal, its irregular surfaces, Fig. studded here and there with enamel prominences, demonstrated at once its odon-tomatous character. As the tooth one year after this time presented no signsof erupting, the second radiogram on the right was made, which shows the incisor Fig. 282.
