[The Bimler method in the treatment of sagittal shift of the skeletal base in Class II division 1 malocclusion]

Inadequate sagittal development of the mandible (class II, division 1 malocclusion), is one of the most frequent in dentofacial malformations. We present the Bimler "gebissformer", removable and functional appliance and its tridimensional action. The treatment can be started during the deciduous dentition or in mixed dentition. Therapeutic results, increase of SNB angle, maxillary expansion, and reduction of the deep bite are presented. While therapeutic failure is observed in 30% of the cases (by absence of tissular response or poor patient compliance), the stability of the results in 70% of the remaining cases and its total inocuity make this appliance an interesting method of treatment.
