Relationship between material and mechanical properties and histomorphometric parameters of bone resorption and formation. (A) Mineral to matrix ratio versus osteoclast surface/bone surface (OcS/BS), (B) mineral to matrix ratio versus bone formation rate/bone surface (BFR/BS), (C) Young’s modulus versus OcS/BS, and (D) Young’s modulus versus BFR/BS. ○, Low turnover; ▲, normal turnover; □, high turnover.
