Distraction osteogenesis in the mandible with a motor-driven plate: a preliminary animal study.
Distraction osteogenesis is an established method for lengthening of the mandible and for reconstruction of bony defects. We report on our first experience with a motor-driven 2.7 mm plate which was fixed at the lingual surface of the body of the mandible in Göttingen minipigs following osteotomy of the mandible. The power supply and the timer module were inserted subcutaneously in a neck pocket. A maximum distraction of 13 mm was observed. Further research is necessary before clinical application of a comparable system.
