Figure 4From: Numerical simulation of in vivo intraosseous torsional failure of a hollow-screw oral implanta) The finite element model of the implant. Note that, approximately 30–35% bone loss is present around the implant, although the hollow part is totally filled with bone. b) The centrally-retained nod and the nodes attached to this node is presented in red color. The rotational force is applied at this node, which coincides with the implant- or the y-axis (purple)Back to article page
