[Surgery before orthodontic treatment: a concept for timing the combined therapy of skeletal dysgnathias].

Abstract

Postsurgical orthodontic treatment will prevent several disadvantages of the presurgical orthodontic approach: 1. Orthodontic tooth-movements do not interfere with compensatory biological responses. 2. The dental arch alignment is similar to the procedures of any class-I-orthodontic treatment; i.e. dental movements can be based on an already corrected skeletal relation. 3. A possible postsurgical relapse may be easily compensated within the postsurgical orthodontic treatment. Presurgical corrections of dento-alveolar discrepancies are only required to limit an excessive vertical disclusion necessary for a correct sagittal and transverse positioning of the jaws.
