ABSTRACT
Objective To evaluate the clinical effect of alveolar bone augmentation by applying autogenous tooth bone graft material to patients with alveolar bone deficiency in orthodontic treatment. Methods Four patients with a stable periodontal condition managed with fixed orthodontic treatment were included, and the number of graft sites was 17. Cone beam computed tomography (CBCT) showed labial alveolar bone deficiency. The treatment plan included extraction, and the extracted teeth were used to prepare autogenous tooth bone material. The alveolar bone width was measured at the same site at multiple heights prior to operation and at 3 and 6 months post-operation.Results The alveolar bone width was higher at both 3 and 6 months post-operatively (P ＜ 0.05) than that pre-operatively. The alveolar bone width at 6 months post-operation was lower than that at 3 months post-operation (P ＜ 0.05). Conclusion Applying autogenous tooth bone graft material to patients with alveolar bone deficiency in orthodontic treatment can expand the range of tooth movement and result in good clinical outcomes.
