A dental implant is a surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or facial prosthesis, or to act as an orthodontic anchor.
Phenomena of tribocorrosion in medical and industrial sectors

Dental implants made from titanium or TA6V4 alloy, consist of a metallic screw inserted into the bone. This screw is surmounted by another metallic or ceramic piece, the abutment, which provides a surface on which the artificial metallic or ceramic tooth can be placed (Figure 1.5). More sophisticated implants such as one piece dental implants made of zirconia have appeared in the market recently (Figure 1.6). The white colour of zirconia is an aesthetic advantage, its high strength to weight ratio, high corrosion resistance and high level of osteointegration and bone-to-implant contact explain the reasons and success of what is now called the ‘new wave’ dental implants.

In recent years, dental implants have become more common in the dental profession (Reddy, Sundram, and Abdemagyd 2019). Dental implants replace missing teeth, restoring function and stability and improving the patient’s oral aesthetics (Jiang et al. 2014). Micromotion is the relative movement that occurs when a load is applied to an implant surface and bone (Haïat, Wang, and Brunski 2014; Han et al. 2021). Movements of a few millimeters (even microns) are too small to be seen by the naked eye. Primary implant instability, variations in implant material and geometry, bone density, installation methods, and the amount and direction of loading all contribute to micromotion (Ellenrieder et al. 2020; Trisi et al. 2015; Winter, Klein, and Karl 2013). Cost-effective and reproducible approaches are required for dental research (Reddy, Sundram, and Abdemagyd 2019). Computer modeling is a noninvasive approach to predict micromotion. Several methods have been used to examine stress distribution on the bones, including photoelastic modeling, strain gauge analysis, and the finite element method (FEM) (Matta et al. 2021; Srirekha and Bashetty 2010).

There is a myriad of ways in which someone may experience an injury relating to the jaw or mouth. When injuries cause the loss of one or more teeth, it may become necessary to have them replaced. Dental implant is a common dental procedure to remedy this issue, which provides a replacement for the foundation of a tooth. An implant consists of an anchor set into the jawbone, an abutment to which the crown is affixed, an attachment screw to connect the abutment to the anchor, and a replacement tooth or crown. Most patients, who are in good health, are generally considered suitable candidates for dental implants. In the U.S., more than 15 million people currently have a crown or bridge replacements for missing teeth, at least 3 million of those with dental implants, and this number is expected to grow by approximately 500 000 people per year [1].

The field of implantology has grown in the past decades, reaching millions of procedures done annually. The current structure adopted for dental implants consist in a metallic fixture (usually made of titanium for biocompatibility reasons) and a ceramic or polymeric prosthesis (Esposito et al. 2013; Magne et al. 2011). The fixture is implanted inside the gum by surgical procedures and undergoes an osseointegration process. Dental implants are a viable solution in solving aesthetic issues and problems in chewing and communication of patients, improving their quality of life (Bränemark 1977; Tamimi et al. 2014).
