In this case the lowerjaw is in post-normal rela-tion with the upper, whichis too short and too narrow,so that the spaces for theerupting canines are toosmall; in the lower jaw allthe teeth are in good align-ment. In order to obtainthe best aesthetic results,the treatment should bewith the object of enlargingthe spaces between thelaterals and first premolarsby expanding the molarseries and moving the in-cisors forward ; at the same. Fio. 372.—Case 5. After treatment. Extraction of the first left molars has allowed forward movement of the second molars, and the bite has closed, so that the right second molars now left upper premolars require backward movement, and the upper incisors can then be drawn back into normal occlusion with the lowar. 243 time the lower jaw should be moved forwardby inter-maxillary force, so as to bring it intonormal antero-pos-terior relation withthe upper teeth. Toeffect this, veryslight movement, ifany, of the lowerteeth would be re-quired. This treat-ment was decided on,but had to be aban-doned as the patientdeveloped scarletfever. The modeof treatment wasreconsidered, andit was thought thatthe simplest methodwould now be desir-able. This case is onethat is tjT3ical of theclass discussed onp. 127, for which ex-traction of the twoupper premolars was accordingly done inOctober, 1901, when thepatient was aged eleven.
