Repair of alveolar bone defects in SD rats. (A). Operational flow chart of alveolar bone injury repair. (B). The model of alveolar bone injury was established. One week later, the alveolar bone injury of rats was observed via Micro-CT. In the figure, the yellow dotted line indicates the location of the normal alveolar bone, and the red dotted line indicates the area of the injury. (C). After 12 weeks of administration, the alveolar bone repair states of different groups of DFH were observed via Micro-CT. (D). After 12 weeks of administration, the alveolar bone defect areas of different groups of DFH were calculated. (E-H). The volume fraction, trabecular number, trabecular separation, and trabecular thickness of the newly formed alveolar bone were analysed using the CTAn software (n = 3, *P < 0.05, **P < 0.01, vs Model).
