title: Facial surface changes after cleft alveolar bone grafting.
abstract: OBJECTIVE
  The aim of this study was to assess the 3-dimensional facial surface changes after cleft alveolar bone grafting with digital surface photogrammetry.
  
  
  METHODS
  In a prospective study, 22 patients with cleft lip and palate underwent alveolar bone grafting. Before the procedure and 6 weeks postoperatively and before the continuation of orthodontic treatment, 3-dimensional images were taken with digital surface photogrammetry. Seven standard craniofacial landmarks on the nose and the upper lip were identified. Their spatial change because of bone grafting was assessed. Statistical analysis was performed with analysis of variance and t test.
  
  
  RESULTS
  A significant increase in anterior projection on the operative side (P < .05) was found for the labial insertion points of the alar base (subalare). No significant changes were detected for the position of the labial landmarks.
  
  
  CONCLUSIONS
  Our results show 3-dimensionally that there is a positive influence of the alveolar bone graft on the projection of the alar base on the cleft side.
