title: [The measurement of utility value for skeletal malocclusion].
abstract: OBJECTIVE
  To measure the utility value of different skeletal malocclusion for patients receiving orthodontic treatment.
  
  
  METHODS
  Utility value of different skeletal malocclusion for patients was measured by rating scale and time trade-off.
  
  
  RESULTS
  The youth group had higher utility values than adult group for skeletal malocclusion Class II (protruding facial type) with median mandibular angle. The utility value of skeletal malocclusion Class III (concave facial type) with low mandibular angle was the lowest, and the utility value of skeletal malocclusion Class II (protruding facial type) with median mandibular angle was the highest. There was no difference in the utility values by rating scale and by time trade-off.
  
  
  CONCLUSIONS
  For some skeletal malocclusion, the youth had different utility values with the adult.
