A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . an important factor by which this and other types of dento-facial malocclusion arise spontaneously, as it were, from forebears in whom no suchcondition has ever before occurred, will solve many heretofore mysterious prob-lems of etiology. 234 PART VI. DEyTO-FACIAL MALOCCLLSIOXS The fifteen pronounced cases of bimaxillary protrusion shown in Figs. 157and 158, arose in the authors practice between the years 1900 and 1912. Thispersonal record of the marked cases of this character, however, hardly begins torepresent the comparative number of these cases found among the mixed types ofthe white race. An observing expert at quick diagnosis of facial outlines will seethem ever>Tvhere, in the cars and crowded thoroughfares of cities, with physiog-nomies characterized by protruding mouths and receding chins. The reason whypersons of this type do not seek more often for correction, though they may beperhaps embarrassingly conscious of their facial imperfection, is that most of them Fig. do not imagine that any operation is possible. Moreover, their dentures are sofrequently in normal occlusion that even dentists, whose thoughts are engagedin saving teeth, upon seeing these seemingly perfect relations, give little thought tothe facial aspect which the dentures produce; or, if they think of it at all, they re-gard these patients as more or less exceedingly homely, as God or inheritancemade them. The same is true of many modem orthodontists who would notconsider for a moment the extraction of teeth from mouths in which the denturesare already so nearly or quite in normal occlusion, and who will doubtless tellyou that all that is necessary in these cases is to widen the arches and retrude thefront teeth.
