title: [Influencing factors on bone resorption after alveolar bone grafting].
abstract: OBJECTIVE
  To retrospectively study alveolar autogenous bone grafting (AABG), the success rate and the factors influencing bone resorption after the surgery for the repair of alveolar cleft.
  
  
  METHODS
  A retrospective analysis was performed in a group of 108 alveolar cleft patients receiving alveolar bone grafts. The method of regression was used for analysis.
  
  
  RESULTS
  The overall survival rate of AABG was 88%, clinical success rate was 60%. The major factors influencing bone resorption were: infection, age, type of cleft, functional stimulation and surgeon. The factors which did not influence bone resorption were: sex, type of surgery, teeth pulling during the surgery and the width of the cleft.
  
  
  CONCLUSIONS
  Surgery at the proper age of patients, orthodontic treatment before surgery, improvement of surgical skills, necessary functional stimulation and control of infection will improve the success rate of AABG.
