Fig. 3. (a) Interfacial shear strength (Jsh) as a function of the mean slope (Rsi) for a
surface roughness consisting of identical repeating elements as shown in Fig. 1b.
Ra = 1.5 pm, implant diameter=4 mm, implant wall thickness=0.5 mm, bone
support=3 mm and Eb = 15 MPa. The results for the Local model are shown as
dotted line. (b) Interfacial shear strength as a function of the Ra value for a surface
roughness consisting of identical repeating elements as shown in Fig. 1b. a=20°,
implant diameter=4 mm, implant wall thickness = 0.5 mm, bone support=3 mm
and Eb = 15 MPa. The results for the Local model are shown as dotted line.
