“…PEEK has been studied and used for over fifteen years as a biomaterial to replace parts of the spine, hip prostheses, and cranial cortices, making it a great alternative for dental implants. Compared with metals, PEEK is non-corrosive, minimizes metal allergies, and has a low specific gravity relative to strength [27][28][29][30]. In addition to its high mechanical and chemical resistance, it has a low elastic modulus (3-4 MPa) that, combined with other materials such as carbon fiber, allows the elastic modulus to be increased to 18 MPa, a value closer to human bone [31,32].…”

The use of titanium as a biomaterial for the treatment of dental implants has been successful and has become the most viable and common option. However, in the last three decades, new alternatives have emerged, such as polymers that could replace metallic materials. The aim of this research work is to demonstrate the structural effects caused by the fatigue phenomenon and the comparison with polymeric materials that may be biomechanically viable by reducing the stress shielding effect at the bone–implant interface. A numerical simulation was performed using the finite element method. Variables such as Young’s modulus, Poisson’s coefficient, density, yield strength, ultimate strength, and the S-N curve were included. Prior to the simulation, a representative digital model of both a dental implant and the bone was developed. A maximum load of 550 N was applied, and the analysis was considered linear, homogeneous, and isotropic. The results obtained allowed us to observe the mechanical behavior of the dental implant by means of displacements and von Mises forces. They also show the critical areas where the implant tends to fail due to fatigue. Finally, this type of non-destructive analysis proves to be versatile, avoids experimentation on people and/or animals, and reduces costs, and the iteration is unlimited in evaluating various structural parameters (geometry, materials, properties, etc.).
