It is well recognized that a cross-bite tends to occur more frequently among Japanese, Chinese and Koreans more than among Europeans.
A variety of functional appliances have already invented for the treatment of cross-bites.
One of them is the FR III( by Rolf Frankel) which applies a quite different philosophy based on the using vestibular region compared with other methods which utilize muscular forces applied directly on the teeth.
The FR III also increases both the lack of muscular tension against the dental arch and the den¡©tition and muscular forces which can then influence the teeth indirectly.
This mechanism can achieve favorable developments with the basal¢¥ bone, teeth, and alveolar bone.
After using FR III to the anterior cross-bite patient with the eruption of a maxillary incisor, the results were as followsI. Forward growth of maxilla and proclination of the upper incisor 2. Downward and backward rotation of the mandible
3. Increase the facial height
4. The case which was normal mandible, underdevelopmental maxilla, deeper overbite and more nagative overjet exhibited good prognosis
