Abstract |
This article describes the use of an activator with anterior high pull headgear to treat a skeletal Class II malocclusion in children in the mixed-dentition phase. A combination of headgear-activator appliance can inhibit forward and downward growth of the maxillary complex while stimulating mandibular growth. The correction of Class II malocclusion can be achieved by careful case selection of a motivated patient with a favorable growth pattern. The patients who have skeletal Class II malocclusions were treated by means of activator with anterior high pull headgear and the following results were observed; 1. Forward and downward growth of the maxillary complex were inhibited 2. Mandibular growth was stimulated and counterclockwise rotation of the mandible was observed. 3. Large overjet and deep overbite were corrected. |
