A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . e front teeth had been placed in arch alignment with a preservation ofall the teeth—the buccal teeth being already in normal occlusion—the result CHAPTER XXIX. DIVISION 2. CLASS I. 237 could not have been other than a further protrusion of the already protrudinglips, with an increase of the receding chin effect. Upon examining the finished facesas they appeared after treatment—one of which is reproduced from a photograph—it appears as if there had been a forward growth of the mandible, because of thegreater prominence of the chin and the almost perfect dento-facial outlines, butthis is wholly due to the retrusive movement of the labial teeth and the harmonizingeffect upon the facial outlines, made possible by the extraction of the four firstpremolars. Soon after the operation was completed, the young man graduatedfrom Princeton, and because of his phenomenal academic ability and brilliancy,he received from the United States Government an important diplomatic appoint- Fic. ment abroad. As this appointment necessarily entails exacting social functionsand relations, one can imderstand his appreciation of the method of treatment hewas finally persuaded to adopt, requiring the extraction of four good premolars,since treatment without extraction would have left a protruding mouth, prominentteeth, and a receding chin, while the result of the other treatment is characterizedby comeliness, self-poise, and intellectuality. In the group of ten bimaxillary protrusions shown in Fig. 158, it will be seenthat they present the same marked character of facial outlines as the formergroup. Fig. 161 is a side view of their dentures in occlusion, showing the samedisto-mesially normal relations of the buccal teeth. Only the right side is shown,as the left is practically the same. Please observe the face on the lower right of Fig. 158, and then turn to
