title: [Clinical study of cancellous iliac bone graft in cleft alveolar repair].
abstract: OBJECTIVE
  To analyze the factors affecting the effect of cleft alveolar repair.
  
  
  METHODS
  21 patients with alveolar cleft who were treated in our hospital between 2003-2007 were included in this study. The factors that affected the cleft alveolar repair such as patient's age, cleft type, surgical method, source of bone were analyzed accordingly.
  
  
  RESULTS
  (1) The surgical success rate was 95.24%, the clinical success rate was 90.48%; (2) The effect of bone graft correlated with the patient's age;(3) Surgical success rate of unilateral alveolar cleft was higher than that of bilateral alveolar cleft.
  
  
  CONCLUSIONS
  (1) The younger patients, the greater chance of success in bone graft. Patients aged 9-11 years are appropriate candidates for the surgery , when the canine is erupting; (2) Iliac bone is a good source for bone graft; (3)Good bone bed and tight tension-free suture are the key to surgical success.
