title: [Initial study and evaluation on alveolar bone graft by palate side approach].
abstract: OBJECTIVE
  To observe and improve the short-term outcome of alveolar bone graft (ABG) by palate side approach.
  
  
  METHODS
  ABG by palate side approach was performed in twenty patients with non-syndromic unilateral complete cleft lip and palate. Eight patients were incomplete cleft alveolar, and twelve patients were complete cleft alveolar. Each patient took cone beam computer tomography (CBCT) before and after surgery. The related data was measured by Image-Pro Plus 5.1 and analyz statistically.
  
  
  RESULTS
  The overall implanted bone mass ratio was 88%, the labially implanted bone mass ratio was 93%, and the palately implanted bone mass ratio was 84%.
  
  
  CONCLUSIONS
  ABG solve the shortcoming of bone insufficient at palatal side. Triangle nasal flap in cranny can assume the closure of nasal floor and palatal mucosa, avoid a large range of relaxation incision and applying of buccal mucosal advancement flap.
