Figure 10 demonstrated the higher density of hydroxyapatite crystals within the approximately 500
nm wide niZ of G-ænial Bond.

next to the presence of 4-met, the phosphoric ester monomer in G-ænial Bond improves the
demineralisation capacity and chemical reactivity with hydroxyapatite. additionally, a nano-
interaction zone (niZ) of approximately 500 nm with a high density of hydroxyapatite crystals can
be observed, leading to the conclusion that the hydroxyapatite chemically reacted with the
functional monomers and remained within the NIZ. Since the collagen fibrils in the niZ are not
exposed, they will be resistant to hydrolytic degradation, thus long-term durability can be
expected.
