A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . ched to a slipper crown on the cuspid,which is not distinctly shown by the picture. This peculiarity is worthy of mentionat this time, because it is one of the many instances which proves what has beenmentioned elsewhere, i. e., that the mandible and other bones which characterize 322 PART VI. DENTO-FACIAL MALOCCLUSIOXS the human physiognomy do not always show inherited disharmonies of size andform in relation to adjoining bones, until sometime after the beginning of adoles-cence. Nor are pronounced inherited peculiarities and characteristics which per-tain to the entire body, indicated at times in a slight degree, until after thirteenor fourteen years of age. The rapid growth of the mandible, in this case, in respon,se to the forces ofheredity after the eruption of nearly all the teeth, opened spaces between thefront teeth, notwithstanding their decided lingual inclination. The family dentistwho had the case in charge, knowing of no other way to close these spaces, inserted Fig. the artificial tooth. The removal of this tooth permitted a lingual movement ofthe roots of the incisor teeth, placing them in a more upright position. At the sametime, the extruding movement, with the occipital force, corrected the open-bitemalocclusion. The two following cases, which are quite typical of this Division, were presentedwith a paper read before the National Dental Association in 1917, mainly toshow the possible rapidity of an extrusive bodily movement, with the correctionof open-bite malocclusion for patients beyond the age of adolescence. The follow-ing is from the published proceedings of that meeting: Fig. 230 shows the casts of a young man twenty-one years of age for whom theoperation for correction was commenced, May, 1910, and ended, as shown, May,1911. The mandible in this case was bent to the right carrying its left body andbuccal teeth far forwar
