Product Overview:

In this tutorial, we investigate the simulation of a dental implant in interaction with the mandible bone under dynamic loads using Abaqus. The model comprises three-dimensional components, including the crown, abutment, and mandible bone. Dental implants are metal posts or frames surgically positioned into the jawbone beneath the gums, providing a stable support system for replacement teeth. This integration allows for the secure mounting of dentures and bridges, which won’t slip or shift in the mouth—this feature is particularly beneficial during eating and speaking. The secure fit also enables crowns placed over implants to feel more natural compared to conventional options.

The crown is modeled using a ceramic material with elastic-plastic behavior and a ductile damage criterion, while the titanium used for the abutment features elastic-plastic properties along with the Johnson-Cook damage model. The mandible bone is represented as an elastic-plastic material. To simulate the dynamic loading conditions, the dynamic explicit procedure is employed.

A general contact algorithm with appropriate contact properties is used to model interactions among the various parts. Suitable boundary conditions are applied to the mandible, and a concentrated force with a smooth amplitude is applied to the crown. Given the complexity of the model, a fine mesh is necessary to ensure accurate results.

During the analysis, the applied force induces stress in the assembled components, allowing for the extraction of critical stress zones from the model.
