The traction- screws and bands upon the cuspids were removed, and the case then presented the appearance shown in Fig. 80. The retaining- bands were worn one year, after which the teeth showed no tendency to return to their former positions. Fig. 80. Section III. Excessive I'rotrusiqx of the Upper Teeth. Fig. 81 represents a typical case of a very marked class of dental irregularities, quite common and always unsightly. The principal characteristic is the excessive prominence of the superior incisors, laterals, and cuspids. The upper lip is always short, probably due to lack of development from being held in an abnormal position, and through inability to close the lips over the prominent teeth. Fig. 81. The lower jaw is generally short, and the occlusion of the molars and bicuspids is usually g(Kjd, although posterior to the normal. As a result the lateral halves of the superior arch are commonly closer than normal, so as to be better acconmiodated to the smaller circle of the lower arch. The lower incisors are more or less irregular, and tluir cutting-edges always occupy a higher l)lane than normal, doubtless owing to the lack of working occlu- sion. As a result of the fre(|ucnt attem])ts at complete closure of the month, the lower lip is forced between the U[)|)er and lower](https://iiif.wellcomecollection.org/image/b2122979x_0071.jp2/full/800%2C/0/default.jpg)
