The size of the bone formation of the host bone was also quantitatively measured in the lateral view. The area was calculated in relation with that in the (MC-; FGF2-) group at 2 weeks in ratio (top). The status of the grafted bone is scaled and the average is given. The scale is as follows: severe bone absorption (-2), mild bone absorption (-1), no change (0), single nodules of bone formation (1) and bridging or lamellar bone formation (2) (bottom).
