title: Establishment of 3-dimensional finite element model of maxillary in human complete unilateral cleft lip and palate with spiral CT scan.
abstract: OBJECTIVE
  To explore a faster and more precise method to establish a 3-dimensional (3 D) finite element model of maxillary in human complete unilateral cleft lip and palate.
  
  
  METHODS
  The surface of the model was created using Materialists Interactive Medical Image Control System (Mimics) software to deal with Dicom standard files obtained by scanning the cranium of the patient with multi-slice helical CT. The 3D finite element model for complete unilateral cleft lip and plate in maxillary was established by Ansys software.
  
  
  RESULTS
  A 3D finite element model of maxillary in human complete unilateral cleft lip and palate was constructed with 27,405 units and 26,876 nodes.
  
  
  CONCLUSIONS
  The combination of Mimics software, Geomagic studio software, Ansys software, and spiral CT is able to create a 3D finite element counter model, which provides a faster and more valid method to study complete unilateral cleft lip and palate.
