A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . nthe center is from the models of a miss twenty-seven years of age, a ceramic artistby profession, whose facial deficiencies were decidedly emphasized by the samedeforming action of the jaws in eating that characterizes this malocclusion. Theone below is from a child about seven years of age. In the correction of this character of malocclusion, it is necessary to breakup the entire occlusal relation of the dentures and place them in normal bucco-lingual dento-facial relations. This is not an easy operation with ordinary ap- 220 CHAPTER XXVII. TYPE F. DIVISION 1.

The work in the more pronounced cases may be greatly facilitated by placinghollow crowns over the first lower molars with heavily built inclined planes to openthe bite and force the dentures to a normal linguo-buccal position while eating. Fig. The teeth are then more easily shifted to their new positions and occlusal relations. Other than this, the various means which may be successfully employed are applicable variations of the usual methods, which need not be described in detail as no two cases are alike. For children who have not shed the temporary buccal teeth—as shown at the bottom of Fig. 145—strong guiding plates attached to stationary anchorages are usually sufficient for the entire correction of the buccal occlusion. Second Form The second form of lateral malocclusion is due to a unilateral malformation ofthe mandible, and arises during the very early developmental processes of the bones,resulting in the production of a more obtuse or straightened angle of the ramusand its condyle upon one side only, in its relation to the body of the mandible. 222 PART VI.
