(A) Stiffness of the interface, k_i, vs. time for three groups of implants tested in BIGI, namely, groups 2, 3 and 6. The interfacial stiffness (N/μm) was obtained from via k_i = k_net − k_w as described in the text. (B) Plot of the time-variation of Young’s elastic modulus (E) of the interfacial tissue, corresponding to the stiffness values in Fig. 5A, as determined from matching finite element models to in vivo measurements of k_net, the net interfacial stiffness
