title: [Three-dimensional design of surgery for mandibular retrusion].
abstract: OBJECTIVE
  To explore the feasibility of surgical design for mandibular retrusion using three-dimensional software.
  
  
  METHODS
  Three-dimensional reconstruction was performed by Mimics software based on the preoperative CT data. The model of the maxillofacial region was imported into Rapidform software for measuring the associated parameters and Geomagic software for simulation of osteotomy. The reliability of the virtual operation was validated during the surgery.
  
  
  RESULTS
  The model of mandibular retrusion was reconstructed and successfully used to simulate the surgery. The simulation result was applied in subsequent actual surgery and good surgical outcomes were achieved.
  
  
  CONCLUSIONS
  The three-dimensional software can be used to simulate the surgery for mandibular retrusion and improve the predictability and accuracy of the surgery.
