title: [CT assisted mandibular osteodistraction with reconstruction of the temporomandibular joint and two piece maxilla].
abstract: BACKGROUND
  The possibilities for computer assisted planning and its surgical conversion with stereolithographic templates are shown for complex maxillofacial surgical interventions.
  
  
  METHODS
  We describe the case of a patient with extreme micrognathia due to an ankylosis of the temporomandibular joint. In addition to the exact determination of the osteotomy lines on the mandibular angle and the segment osteotomy of the maxilla, vectors of the bidirectional osteodistraction were also predictable.
  
  
  CONCLUSIONS
  In comparison with the conventional procedures, computer assisted planning achieved a much higher degree of precision and safety with reduced complication rates. The CMF module is a component of the SimPlant software which enables the precise planning of osteotomies and osteodistractions.
