Fig. 3From: Influence of biodegradable polymer membrane on new bone formation and biodegradation of biphasic bone substitutes: an animal mandibular defect model studyHistologic analysis on the experimental and control groups. a At 4 weeks, newly formed bone volume was similar between the groups, but remaining graft volume was higher in no membrane group than osteoguide membrane group. b At 8 weeks, there was no significantly difference of newly formed bone and remaining graft volumes between the groups. * Krustal-Wallis Test is significant at the 0.05 level (2-tailed)Back to article page
