A dental implant development and manufacturing organization is interested in carrying out FEA on a implant design.The implant will be made from a polymeric composite material. The implant is of screwable design. The dental implant is thus screwed on the abutment. The goal of the analysis was accurate simulation of various deformation modes.
Analysis was carried out by first simulating the pre-compression and then application of a uniform pressure on the top area in the second step.
The physics involved in the simulation are complex and can be summarized as follows:
- Non-linear material property of the composite material had to be included.
- Large expansion deformation along with multi-step analysis procedure had to be carried out.
