title: [Establishment and research of the computerized profile and photo prediction system].
abstract: OBJECTIVE
  The study aims to develop a lateral oral facial profile and photo prediction system and then to verify its reliability.
  
  
  METHODS
  24 paired lateral cepholagrams in both pre- and post-treatment were selected and analyzed by three soft tissue cephalometric analysis methods in this study. All cases were of the angel II division I malocclusion, and had been successfully treated with the orthopedics therapy by activator or Frankel appliance. Soft tissue profile prediction had been automatically completed, following the hard tissue interactive orthopedics prediction approach in the pretreatment lateral cephalogram, and the predictive results were compared to the same cepholametric analysis in post-treatment cephalogram.
  
  
  RESULTS
  There are 19 coincidence indicators in 30 measurements of three soft tissue cephalometric analysis, and 7 in 9 angel measurements, 10 in 18 instance measurements, 2 in 3 instance ratio measurements is consistency, respectively.
  
  
  CONCLUSIONS
  The results indicate that the lateral oral facial profile and photo prediction system is effective in profile prediction.
