From: Negative pressure technology enhances bone regeneration in rabbit skull defects
Bone density of rabbit parietal bone at 2, 4, 6 and 8 weeks after surgery. At 4 and 6 weeks after surgery, the bone density of rabbit parietal bone in experimental group was significantly higher than that in control group. At 2 and 8 weeks after surgery, there was no significant difference in bone density of rabbit parietal bone between experimental and control groups (* denotes P <0.05).
