The etiology of osseous deformities of the head, face, jaws and teeth . ard palate was flat and normal, showing that the pressurewas direct upon the teeth, and that the thumb did not comein contact with the tissues of the mouth. When the habit iscontinued during the development of the permanent set, thedeformity is more marked, because there is more leverage, asis shown in Fig. 234. This is a case in which the palate isflat and normal, showing that the pressure was direct upon theteeth, and that the thumb did not come in contact with thetissues of the mouth. The superior jaw and teeth are broughtforward by absorption and deposition of bone-cells, and thelower teeth and jaw are carried inward. THE HEAD, FACE, JAWS AND TEETH 479 These cases are so unlike those of any other form of irregu-larity of the permanent set that it would seem impossible tooverlook the cause. The alveolar process and teeth assumethe shape of the object or thing sucked. Fig. 235 shows the front view of a case of teeth have developed their normal length; but arrest of. Fig. 2.^4.
