A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . the apparatus for the bodily labial movementof the incisors. The final dental and facial casts were made upon the removal of CHAPTER XLIII. DIVISION 2. CLASS III. 303 this apparatus, and show the teeth in position for the retaining appHance on thefront teeth, and the final adjustment of the buccal occlusion. Cases of this charac-ter at a youthful age rarely take over one year to correct. In many cases, the effect of adenoids will result in inhibited maxillary develop-ment of the intermaxillary portion of the bone only. When this causes the earlyerupting incisors to close back of the lowers, inlocking them in that malpositionand preventing the development of all the incisive portion of the bone, it producesall the characteristics of an upper retrusion, notwithstanding the normal occlusionof the buccal teeth. This is fully shown in Fig. 213 which illustrates a case that belongs to Class I, asmay be seen by the normal disto-mesal relations of the buccal occlusion at the begin- FiG. ning of the operation. It is presented in this Class, because of its similarity in facialcharacteristics and demands of treatment. It can be seen by the dental cast madebefore treatment that the cuspids are crowded out of alignment. But the bodily re-truded position of the incisors (shown by their normal inclination) and lingual alveolarridge plainly indicates that the inhibiting causes operated only in that locality. The final facial and dental casts show most perfectly the action, effect, andpossibilities of a bodily labial movement of the upper incisors, which in this casecarried the entire incisive alveolar ridge forward with the movement of the roots,as shown in the enlarged occlusal aspects of the dentiires. This case was begun in1892, and when finished, the casts were mounted and exhibited at the August,1893 meeting of the International Dental Congress. The profil
