A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . maybe considered the simplest of that mostcommon malposition which is character-ized by maleruption of the cuspids. It isplaced in this group because a simpleresilient alignment bow No. 23, as shown,will commonly correct it with little atten-tion . The effort of natiire to erupt crowded^ ™» cuspids, will at times extrude the centrals. _^ V Should all of the incisors demand a sUghtlabial movement to enlarge the arch andgive more room for the cuspids, the lat-erals can also be banded with open-tube,or small hook attachments. If this con-dition is somewhat marked, it may benecessary to use an expansion arch-bowthreaded for nuts at the mesial ends ofthe molar tubes. Again, if the premolarshave been forced into lingual malalign-ment, or if the premolar area demands a slight expansion, additional applianceswill be indicated. This apparatus is applicable only to those cases in which the cuspids demandslight movement and little artificial aid. For the application of greater force, see 331. 332 PART VII. UNCLASSIFIED MALOCCLUSIONS Class I. In this connection, it should always be remembered that in the commoncourse of secondary dentition, the cuspids are often naturally crowded out of theirnormal alignment, and when the direct cause of this amounts to no more than aslight constriction of the space required, nature will usually correct the malpositionfor young patients by the natural growth of the jaw.
