title: [Three-dimensional analysis of craniofacial growth in adolescents with normal occlusion in Beijing].
abstract: OBJECTIVE
  To analyze craniofacial growth three-dimensionally for adolescents with normal occlusion in Beijing.
  
  
  METHODS
  One hundred and twenty-six adolescents with normal occlusion were selected according to the criteria. The sample was divided into four age groups (53 within 4 years, 30 within 7 years, 27 within 10 years and 16 within 13 years). Information of growth was collected. Three-dimensional cephalometric system based on cone-bean CT was established.
  
  
  RESULTS
  From 4 to 13 years Co-A increased (14.55 ± 1.15) mm on average on the left and (13.66 ± 1.14) mm on the right, and Co-Gn increased (22.89 ± 1.40) mm on the left and (22.82 ± 1.38) mm on the right; and U1-NA increased (2.20 ± 0.44) mm on the left and (1.60 ± 0.46) mm on the right; and CoL-CoR and GoL-GoR increased (13.31 ± 1.21) mm and (18.59 ± 1.40) mm, and N-Me increased (18.03 ± 1.32) mm.SN-PP and SN-MPL basically remained unchanged.
  
  
  CONCLUSIONS
  Adolescents with normal occlusion in Beijing grew obviously in three-dimensions and developed harmoniously.
