Evaluation of osteogenesis of alveolar bone graft by cone beam CT

Abstract

To evaluate the osteogenesis of alveolar bone graft (ABG) in patients with alveolar cleft by cone beam CT (CBCT). ABG surgery was performed in 20 patients with unilateral complete alveolar cleft. The patients were followed up for 3 and 6 months after surgery and the osteogenesis of the bone graft was evaluated by CBCT. The bone density and the height of labial and palatal bone graft area were analyzed. There was no significant difference in the bone density between 3 months [(403.79 ± 64.70) HU] and 6 months[(411.45 ± 42.62) HU ] (P = 0.329).However, there was significant difference in bone height in the labial and palatal side between 3 months and 6 months (labial P = 0.020, palatal P = 0.008). The osteogenesis was the best 3 months after bone graft. The following treatment can start in this stage.
