[The treatment of deep bite in adults].

UNLABELLED

49 treated adult patients with deep-bite were classified by analysing orthodontic models and lateral cephalograms differentiating skeletal, dento-alveolar deep-bite and class I, class II-1, class II-2 malocclusion. Change of overbite and position of incisors were described within every group and compared with the other groups.

RESULTS

On the average overbite decreased about 3.5 mm, mostly however combined with root resorptions in the maxillary front. After removing the appliance overbite relapsed about 1.7 mm at 93.3% of cases. The percentage of factors which made possible a decrease of overbite was described and parameters which caused the relapse were discussed. Interpreting the results of orthodontic treatment in adults, it seems to be legitimized in some exactly indicated cases but, treatment in adults is not the best time for correcting deep-bite.
