The mesh of the components is simplistic and consists of linear
tetrahedron elements with four nodes (Fig. 7). Since the interface
of bone–implant experiences the largest deformations under
load, it is necessary to mesh this boundary into small elements
(Fig. 8). The implant system and the bone are meshed with
increasingly larger elements as the distance from the interface increases,
with the size of elements in contact with the interface
being defined by the elements of the boundary mesh. The mesh
of the components is verified for use in a finite element stress
analysis.
