The headgear is an extraoral appliance which used to distal movement of the teeth,
inhibition of maxillary growth and reinforcement of anchorage. In case of treatment of
Class ¥± malocclusion, however, it is not sufficient to simply restrict the horizontal
growth of maxilla but to need treatment on mandibular retrusion. Generally, the
combination theraphy of activator and headgear is conventional, but other study about
comulnatlon therapy with other intraoral removable appliance is done. In this case,
treatments were done by the combination therapy of headgear and anterior bite plate.
The results were followed :
1. Reduction of SNA, upper lip to esthetic plane and lower lip to esthetic plane were
observed.
2. 1 to FH plane angle was corrected.
3. Severe overbite, large overjet, and deep curve of spee was corrected.
4. Class ¥± molar relation was changed by class ¥°.
