Figure 5From: Negative pressure technology enhances bone regeneration in rabbit skull defects X-ray radiopacity. At 4 weeks and 6 weeks, the X-ray radiopacity of the bone formation in the experimental group was higher than that in the control group. At 2 and 8 weeks, there was no significant difference between the experimental and control groups. For each time point, the number of rabbits is 5 and the number of holes is 10. (N = 5, * denotes P <0.05).Back to article page
