Distraction osteogenesis in collapsed mandible arch patients by accidents / 대한치과교정학회지

ABSTRACT

The symphyseal mandibular fractures due to accidents happened in form of collapsed transeverse arch and multiple teeth loss. And the collapsed transverse arch in mandible occurs with unilaterally or bilaterally. So that patient needs to recover arch width. Conventional approaches, however, are difficult to get appropriate transverse arch correction. Distraction osteogenesis is a unique form of clinical tissue engineering and biologic process of new bone formation between bone segments that are gradually separately by incremental traction. Distraction osteogenesis is considered that great potential for correcting transverse mandibular deficiencies. In this paper, distraction osteogenesis applied to patients who had a unilateral or bilateral collapsed arch width in mandible. But it was necessary secrutinize consideration about periodontal conditions, biomechanical vectors, TMJ adaptations, and neuromuscular change during distraction osteogenesis period.
