The histological examination. The residual membrane at 4 weeks after operation was less observed in the middle group (a) than in the total group (b) (bar = 1.0 mm, hematoxylin and eosin stain). New bone formation at 8 weeks after operation was more observed in the middle group (c) than in the total group (d) (bar = 1.0 mm, hematoxylin and eosin stain). The boxed area of low magnification views (a–d) were magnified and shown in e–h, respectively (bar = 50 μm)
