Abstract:
Analysis of 20 cases of Class III malocclusion treated with the FR.III showed that correction of the anterior crossbite was effected by adjustment of incisor inclinations and backward rotation or repositioning the mandible accompanied by an increase in face height. Subjects which responded most favourably to the FR.III were those with severe Class III malocclusion and a deep incisor overbite.
