the cases shown in this clinic were treated with the lingual and plain A LLlabial arches with slig ht variation to meet the conditions involved. The types of overbite, as seen by the models varied from the neutroclusion class with retrudin g anterior teeth to distoclusion cases with protruding anterior t eeth .

Along with t he ling ual and labial appliances, intermaxillary elastics were used. In the neutroclusion cases the elastics served to st abilize the mandibular molars, while th e other t eeth were mov ed forward and in the distoclusion cases the elastics h elp ed bring all the mandibul ar teeth forward.

Norborne F. Muir Fig. 2 shows the lateral view of models described under Fig. 1.
Fig. 3 shows the lingual appliances used in case described under Fig. 1. The lingual arches have recurved finger springs soldered gingivally on the base wire. Time of treatment four years. CASE 2.-Fig. 4 is an anterolateral view of an overbite case of a boy aged twelve. The model on the left shows the case before treatment with the lingual arch in place. Note the wire loop soldered on the labial arch wire anterior to the buccal tube for the purpose of adjusting the appliance. The model on the right shows the completed case one year after removal of the appliances. Time of treatment three years. CASE 3.-Fig. 5 shows the model of an overbite case of a boy fourteen years of age. The four maxillary anterior teeth are retruding and the canines are crowded out of line labially. The model on the right shows the completed case. Fig. 6 shows the lingual aspect of the case described under Fig. 5 before treatment. Fig. 7 shows the lingual aspect of the completed case shown in Fig. 5. Time of treatment four years. CASE 4.-:F'ig. 8 shows the anterior aspect of the case of a boy aged fifteen before and after treatment. This case had marked overbite with protruding maxillary incisors.
Fig. 9 shows the lateral view of case shown under Fig. 8. Time of treatment three and one-half years. CASE 5.-Fig. 10 shows the anterior view before and after treatment of an overbite case of a girl aged eleven. This was a typical distoclusion case with extreme overbite causing the mandibular anterior teeth to close well into the roof of the mouth. The maxillary right central and lateral incisors were retruding while the left central and lateral incisors were protruding. There was very little space for the eruption of the mandibular second premolars.
