Correction of deep overbite. A modified splint permitting rapid extrusion of posterior teeth

The use of a modified splint in the surgical-orthodontic treatment of Class II deep overbite deformities is presented. The splint permits a reduction of the preoperative orthodontic treatment-time because hardly any (time consuming) levelling of the dental arch is indicated while the time of postoperative orthodontic treatment is shortened, because of the possibility of continuing orthodontic treatment during the intermaxillary fixation period. The clockwise rotational movement which occurs with this treatment modality has, additionally, a favourable effect on the anterior facial height and in many cases on the position of the chin. Finally the intake of food during the immobilization period is facilitated.
