Distraction Osteogenesis Of The Maxilla - Indication And Use Of External Devices

Maxillary distraction has evolved into an established treatment approach for the correction of severe maxillary retrusion (> 10 mm) resp. in the compromised maxilla. By now external halo-borne devices dominate over intraoral distractors due to the complex anatomy and difficult vector control. Because of potential dental complications, bone anchorage is suggested. Relapse after distraction is comparable to conventional orthognathic surgery, complications, however, although less severe in most instances are on a significantly higher level.
