Finite element analysis of dental implant in Abaqus



Dental implants are playing an important role in dentistry. There are many parameters that affect the efficiency of the implant which require extensive studies. Before explaining the process of the dental implant in Abaqus we provide some background.

Abaqus in Biomehcanics:

The Finite Element Method (FEM) is a numerical method for solving various engineering problems. Abaqus software is one of the most powerful finite element software to solve various problems with complex geometries and components. The software provides a great environment to study various models. Not even solid mechanics but also thermal and fluid mechanic models can be simulated in this software. It is worth mentioning that the fluid mechanic model was separated after Abaqus 6.16 and since version 2017 the company started to develop an independent solver for it.

Extensive use of dental implant in Abaqus and biomechanics shows the importance of using simulations in this field. These studies require the model of the anatomy as it is in reality. This leads engineers and researchers in mechanical and biomedical engineering to study each component in more detail. These studies are significantly important for manufacturing implants.


The implants fuse to the jawbone and provide stable support for artificial teeth. Dentures and bridges mounted to implants will not slip or shift in the mouth which is a significant benefit for eating and speaking. This secure fit helps the dentures and bridges and individual crowns placed over implants feel more natural than conventional bridges or dentures.

Dental Implant in Abaqus:

In this tutorial, you will see the effects of the implant thread pitch on the created stress in jawbones. Also, we evaluate the implant-abutment by using the finite element method. This tutorial studies the difference between the two types of thread profiles and their effects. In order to have a strong evaluation, the maximum stress between the implant and jaw bone is studied quantitatively. For this purpose, we simulate the dental implants in Abaqus.

Modelling process:

We start the simulation by modelling the superstructure (crown), abutment, and mandible bones in three-dimensional parts. Then, we assemble the simulated components and divide the bone into cortical and spongy parts. Since the process is static we use a static general step and consider titanium alloy as the material for the implant. Next, we choose the bone’s mechanical properties for cortical and spongy parts separately. We use the ceramic material with elastic behaviour for the superstructure component. This is due to the fact that the superstructure never experiences the plastic region and if it excises yield stress it is considered as part failure. The jawbone is also modelled as an elastic material because of the same reason.

In this simulation, we consider different thread profiles. In order to achieve accurate results, we define the friction contact interaction between the implant and the bone. We apply the load as amplitude to mimic the chewing process. In the results section, we will compare the stress between the bone and implant. The general contact algorithm with contact property is beneficial in this simulation and we use it for all contact surfaces between the parts. We assign the customary boundary condition to the mandible and concentrated force with smooth amplitude for the superstructure. The mesh should be fair because of the complexity of the model.


The thread pitch ranged from 0.95 mm and 1.1 mm. Results suggested that under axial load when the thread pitch is 0.95 mm the minimum stresses were obtained. Thread pitch played a significant role in protecting dental implant under axial load and thread pitch 0.95 mm was a better selection than 1.1 for a screwed implant by biomechanical consideration.

This simulation can be constructive in many fields, especially the biomechanics industry and companies in the mentioned area. It can give you some insights for modelling biomechanics simulations and implant design.
