X-ray images of the implanted specimens after 4 weeks: no implantation group (a), plain β-TCP (b), AP/β-TCP (c), and BP/β-TCP (d). X-ray images of the implanted specimens after 8 weeks: no implantation group (e), plain β-TCP (f), AP/β-TCP (g), and BP/β-TCP (h). With time, bone formation was obviously observed at 4–8 weeks with evidence of the gradual decrease in the defect gap and the increase in the volume of new bone. Micro-CT images of the implanted specimens after 8 weeks: no implantation group (i), plain β-TCP (j), AP/β-TCP (k), and BP/β-TCP (l). The red color represents the newly formed bone tissue
