Abstract: PURPOSE: To evaluate the osteogenesis for patients with malocclusion after augmented corticotomy-assisted surgical orthodontics. METHODS: Forty-two patients with malocclusion augmented corticotomy-assisted surgical orthodontics were selected in this study. The patients were divided into 2 groups, twenty-two were treated with Rebone (group 1), twenty were treated with Bio-oss (group 2). Cone-beam CT was used to measure the alveolar bone indexes of the two groups at different time(T0: preoperative, T1: after 2 week, T2: after 3 month, T3: after 6 month). SPSS 21.0 software package was used for statistical analysis. RESULTS: Among the 42 patients, the labial bone height (HL) in group 2 increased from T0 to T2 (P<0.001); the apical labial bone thickness (TL1) and middle root labial bone thickness (TL2) increased from T0 to T1 and decreased from T1 to T2 (P<0.001). CT value of the area without bone graft(CTn) decreased from T0 to T1 and increased from T1 to T3(P<0.001). CT value of the bone graft area(CTg) decreased from T1 to T3(P<0.001). The differences of TL1, TL2, CTn, and CTg between the two groups were significant(P<0.001). CONCLUSIONS: Patients with malocclusion can achieve sufficient bone increment in the operation area through augmented corticotomy-assisted surgical orthodontics, without periodontal injury and root resorption. The osteogenic effect of the two materials was ideal, and the osteogenesis was stable after half a year follow-up.
