title: [Schuchardt's procedure and surgery of open bite].
abstract: Posterolateral segmentary maxillary impaction osteotomy has a role to play in the treatment of gaps between the upper and lower jaws. It has several advantages, especially an uncomplicated postoperative period and the single-maxillary contention it provides. The indication must be established after an articulator assessment in order to take into account the mandibular protrusion caused by autorotation and to prevent a sagittal shift. Associated marginal glossectomy will frequently be required. Similarly, in case of vertical excess, genioplasty for vertical reduction will improve the facial balance. This technique may also be proposed as "pre-prosthetic surgery" in cases of egression in the premolar and molar areas, for which it has shown excellent results.
