Table 1.

Semi-quantitative scoring parameters for evaluation of bone regeneration.

Score Extent of Bone in Defect
0 No bone formation
1 Minimal bone formation (one very small area in the defect)
2 Low bone formation, occupying only small portion of the defect
3 Moderate bone formation, occupying substantial portion but less than three quarter of the defect
4 Abundant bone formation, occupying greater than three quarter of the defect
5 Complete mature bone formation, occupying greater than three quarter of the defect with obvious abundant mature marrow cavity
