abstract: OBJECTIVE
  To investigate the patients who need the orthodontic treatment before and after alveolar bone grafting; the selection of the indications and so on.
  
  
  METHODS
  To select 20 patients with cleft lip and palate, each of them is treated by edgewise appliance, light-wire appliance or removable appliance half to one year before the operation.
  
  
  RESULTS
  After orthodontic treatment, the patients' maxillary teeth are drawn up in order; the distorted teeth have the right positions; the shape of the arch is normal and the teeth beside the cleft are no longer oblique. All of these give a good space to the grafted bone.
  
  
  CONCLUSIONS
  The orthodontic treatment before and after alveolar bone grafting is an important composition of serial treatment of cleft lip and palate. It not only gives a promise to the successful operation, but also makes patient a better shape and function of the occlusion.
