title: [The compensation of post-treatment incisor torque in sagittal jaw relationship].
abstract: OBJECTIVE
  To investigate the dental compensation in different sagittal jaw relationships.
  
  
  METHODS
  One hundred and fifty-seven post-treatment cases with satisfied outcome were chosen. Computerized cephalometric analysis was performed to evaluate the sagittal jaw relationship. Incisor torque were measured based on study models. Correlation analysis was performed.
  
  
  RESULTS
  Compared with skeletal class I cases, the upper incisors of skeletal class III cases were more proclined, and lower incisors were more retroclined; the opposite result was found in skeletal class II cases. Dental compensation in class I cases took place primarily at lower incisors.
  
  
  CONCLUSIONS
  Incisor torque control was important in patients with various sagittal jaw relationships.
