The etiology of osseous deformities of the head, face, jaws and teeth . e bicuspids andmolars are carried in one direction and another, eifecting avariety of irregularities. I have frequently observed hyper-trophy in connection with epilepsy. This is owing to theunstable tissue-building, as noticed among degenerates. Acommon form is shown in Fig. 26. Similar irregularities arealso seen in Coles Deformities of the Mouth, Figs. 12, 13,and 27; and in Tomes Dental Surgery, Fig. 90. These 110 ETIOLOGY OF OSSEOUS DEFORMITIES deformities till take the contour of the saddle-shaped may be accounted for from the fact that the permanentmolars, being the first teeth to erupt, become fixed beforethe deposit commences. The crowns of the bicuspids arealso held in a small circle by the retention of the temporarymolars. When these teeth do not antagonize they are liableto be carried inward. The cuspids, with their long roots, meet resistance eitherin connection with the teeth adjoining or with those upon theopposite jaw, and are thus held in position. It will be. Fig. 27. observed that, in all of these cases, the enlargement seems tobe associated with the inner plate of the alveolar observation in these cases has been that with most ofthem the inner plate is the part of the alveolar processaffected. The outer plate, although quite irregular from thearrangement of the teeth, is usually normal in disparity in the two plates of the alveolar process maybe accounted for from the fact that the inner plate of thealveolar process possesses a large blood-supply—the posterioror descending palatine arteries furnishing the ossific author has observed a few cases where the hypertrophy THE HEAD, FACE, JAWS AND TEETH 111 has extended to and included the outer plate. When theouter plate becomes involved the alveolar process assumes avery thick condition. Occasionally, hypertrophy will affectone side only or one distinct locality. Fig. 27 illustrate
