[Distraction osteogenesis in maxillofacial surgery].
With distraction osteogenesis (DOG) formation of new bone is initiated by gradual separation of osteotomized bone fragments. Both external and internal distraction devices are available. Since its first application in craniomaxillofacial surgery in the early nineties, developments in distraction osteogenesis have been tremendous. Important advantages of this technique are: lack of a donorsite and its associated morbidity; increase of the volume of the soft tissue envelop; less surgical trauma compared to conventional craniomaxillofacial procedures; and the usability of the technique in growing individuals. Disadvantages of DOG are: the sofar limited experience and follow-up in craniomaxillofacial surgery; and the unknown influences on growth. The technique will gradually find its niche and the general dentist will therefore be increasingly confronted with its specific indications. In this paper the general principles of DOG and a number of indications in craniomaxillofacial surgery are discussed.
