Figure 5. Simulated finite element (FE) model of the (a) mandibular implant with wing plate, (b) abutment, (c) bone screws, and (d) mandibular.

Table 2. Material properties of the finite element (FE) models involving the mandibular implant, abutment, screws, and bone.

Material Elastic modulus (MPa) Poisson’s ratio Reference
Trabecular bone 1600 0.3 22
Cortical bone 14,800 0.3 22
Abutment and screws 110,000 0.35 22
Mandibular implant From Table 3 0.3
Note: The values of the elastic modulus are adapted from Table 3, which were obtained through in vitro experimental testing.
