Alveolar distraction osteogenesis. Different Clinical Applications. Teil II


Distraction osteogenesis is a well known clinical procedure in medicine. It was widely used by orthopedic surgeons for lengthening the extremities. Distraction osteogenesis was used in dentistry for the treatment of congenital malocclusions and for the treatment of severe skeletal abnormalities. In conventional distraction osteogenesis bone length is increased along a straight line. Transporting distraction disc along a straight line is very usefull in the areas where straight distraction will be in accordence with the morphogenic pattern. On the other hand for the treatment of some problems where straight distraction will not be in accordance with the anatomical structures,distraction along a curve is required. A method which is called Archwise distraction was developed for the transport of distraction disc along a curve.Special distractor which was named as Archwise Mini Distractor was developed and a special appliance was fabricated.

In the first part of this presentation ,Philosophy of Distraction Osteogenesis and the Idea of Archwise Distraction will be discussed and the special appliance (AWDA APPLIANCE) will be introduced. In the second part of the presentation, treated cases with alveolar distraction osteogenesis will be presented and the results will be discussed.
