title: A novel modular retention system for midfacial distraction osteogenesis.
abstract: Distraction osteogenesis of the midface offers new possibilities for the treatment of large sagittal discrepancies between the upper and lower jaws. The use of an extraoral halo-borne distractor, which allows free three-dimensional vector control, may cause problems in the connection between the midface and the distractor. To overcome these difficulties, we present a new modular retention system to gain bone anchorage whenever a toothborne appliance is not suitable. Distraction osteogenesis with an extraoral appliance is therefore possible even in edentulous elderly patients. We have used this system successfully in 11 patients.
