title: [The choice of a surgical method for the correction of sagittal over and under development of the mandible].
abstract: The experience gathered in the correction of sagittal mandibular over- and under-development allows to make the following conclusions:--In the choice of osteotomy it is necessary that careful consideration be given not only to the proportions of the body and ramus of the mandible, but also to the angular interrelationships of mandibular bones.--Osteotomies in the body of the mandible are indicated especially in those cases where it is only necessary for parallel shifts to be made in the sagittal plane.--Osteotomies performed in the region of the angle of the mandible and the ramus of the mandible (Obwegeser-Dal Pont) enable both longitudinal compensation or adjustment in the sagitta. plane and correction of transverse deformities and unfavorable angular relationships.--In the case of backward and forward displacement of the lower jaw it is essential that the position of the chin be considered already in the stage of planning the surgical operation. Suitable corrections can be made in the course of one surgical intervention.--Preliminary orthodontic treatment, because of the creation of optimum conditions of occlusion, will in many cases provide most favorable prerequisites of a surgical intervention.
