PURPOSE: To determine the bone absorption at different time after alveolar autogenous bone grafting using spiral CT three-dimensional reconstruction.
METHODS: Twenty unilateral cleft lip and palate patients(15 males,5 females) were chosen to undergo three-dimensional CT scans after alveolar bone graft, region of interest(ROI) volume measurement of GE AW 4.1 software was used to calculate the capacity of alveolar cleft at 1 week, 3 months, 6 months after surgery.
RESULTS: An average bone loss of 35.74% was found after 3 months, 55.89% after 6 months. In labial and palatal direction, labial bony bridge was more obvious than palatal bony bridge.
CONCLUSIONS: Bone resorption is present after alveolar bone graft, and becomes more severe with time going on.
