Unfortunately, this type is not at present fully recognized by the strict adherentsof the Angle system, as belonging to marked malocclusions which demand correc-tion, because in its typical form, the dentures are in normal occlusion. Yet if thereis any type in dental orthopedia which demands extensive correction when it occursin the white race, it is this. Fig. When these cases present for treatment, especially as they frequently^do afterthe eruption of the second molars, with the teeth crowded closely together in archesof nearly or quite normal width, with receding chins, and decidedly protrudinglips which are closed with difficulty over the protruding dentures, every competentorthodontist must see that there is no way to correct the facial outlines of thesepatients by an orthopedic movement of the teeth without extraction.
