Feedback Excellent Work - looks like you have a good understanding of this weeks learning objectives



Question 1 CorrectMark 1.00 out of 1.00


Of the following, which type of biomaterial would be most appropriate for use in a porous synthetic bone graft substitute?

Select one:

a. Titanium aluminium vanadium alloy (Ti-6Al-4V)

b. Hydroxyapatite (Ca10(PO4)6(OH)2 

c. Aluminium oxide ceramic (Al2O3)

d. Ultra high molecular weight polyethylene




Your answer is correct.

The correct answer is: Hydroxyapatite (Ca10(PO4)6(OH)2




Question 2 CorrectMark 1.00 out of 1.00


How are changes in the physico-chemical properties of hydroxyapatite based synthetic bone graft substitute materials hypothesised
to influence the bioactivity of these medical devices?

Select one:

a. Substituting silicate ions in the crystal lattice of hydroxyapatite directly promotes attachment and osteogenic differentiation
of pre-osteoblast and un-committed mesenchymal stem cells

b. Altering the surface charge and the hydrophilicity by substituting additional ionic groups into the crystal lattice of
hydroxyapatite can directly promote attachment and osteogenic differentiation of pre-osteoblast and un-committed
mesenchymal stem cells

c. Increasing the hydrophobicity and the roughness results in greater quantities of protein adsorption which enhances
attachment and osteogenic differentiation of pre-osteoblast and un-committed mesenchymal stem cells

d. Optimal manipulation of surface charge and hydrophilicity can increase affinity and activity of key adhesion molecules 
to promote attachment and osteogenic differentiation of pre-osteoblast and un-committed mesenchymal stem cells




Your answer is correct.

The correct answer is: Optimal manipulation of surface charge and hydrophilicity can increase affinity and activity of key adhesion
molecules to promote attachment and osteogenic differentiation of pre-osteoblast and un-committed mesenchymal stem cells
