[The dental and skeletal effects of the jumping-the-bite plate and high-pull headgear combination. A clinical study of treated patients].
While planning treatment of the 30 patients with a dental and skeletal class II anomaly on which this study is based, the primary treatment goals were correction of the dental and skeletal structures and attenuation of vertical growth by means of influencing the maxillary skeletal structures and the resultant mandibular reaction. The desired treatment results were achieved in all patients. Even so, however, the effects on individual patients in respect to skeletal influences were markedly different. It was especially helpful that during therapy simultaneously with exerting influence on the maxillary base plane, the influencing of the occlusal plane occurred in the same direction. Through the additional application of high-pull headgear, maxillary growth was clearly restrained and the inclination of the maxillary base plane inhibited. Even difficult skeletal discrepancies, sagittal as well as vertical, can be treated with the bite-jump appliance in combination with a high-pull headgear. This also makes it possible to achieve protrusive repositioning of the mandible in patients with a pronounced vertical growth pattern without causing on open bite. In retrospective the patients' treatment plans proved to be completely appropriate, however, the fact should not be overlooked that changing the occlusal plane is essential for the realization of a positive therapeutic result.
