The correlations between the two mechanical tests and between these tests and bone densities were also considered. The results showed all of the three mechanical parameters, ultimate load, stiffness, and ultimate strength, measured by the indentation test were higher than those measured by the compression test. Correlation analysis showed that the two sets of mechanical values correlated well (r=0.823-0.952, p<0.01). The apparent density and ash density correlated well with the mechanical parameters determined by the two types of mechanical tests (r=0.737-0.966, p<0.05). | lld:pubmed |
