What Materials are Used for Teeth Implants?

Dental implants are a reliable way to restore lost teeth, and the materials used for them have been extensively researched in recent decades. Titanium is the most common material used for dental implants, as it is highly biocompatible and has a 95 percent success rate. Other materials, such as zirconium and alpha-beta combined alloys, are also used for dental implants. These materials must demonstrate adequate toughness and strength, and the implant design must be compatible with its physical properties.

The physical and chemical properties of implant materials are well-informed and documented factors that influence the clinical outcome and prognosis of implant treatment. Titanium is the most popular material used for dental implants due to its biocompatibility. This means that the body rarely rejects it. Titanium or zirconium are the most used materials in the placement of dental implants. The implant post is screwed into the jaw and serves as the base for the new tooth.

The material must have the right toughness and strength and be biocompatible, meaning that it looks like the human body and can fuse with the jaw naturally. The alpha-beta combined alloy is also used for the manufacture of dental implants. This alloy is made up of 6% aluminum and 4% vanadium (Ti-6Al-4V). The heat treatment of these alloys, which generates fine precipitation, improves their strength, which translates into favorable mechanical and physical properties that make them excellent materials for implants. They have a relatively low density, are strong and very resistant to fatigue and corrosion. Although they are stiffer than bone, their modulus of elasticity is closer to bone than any other implant material, with the exception of pure titanium.

This lower elastic modulus is desirable, as it results in a more favorable stress distribution at the bone-implant interface. Ideally, implant materials should be biocompatible and resistant to both corrosion and fracture. Regardless of the material used in your dental implants, finding an implant dentist with the right training and experience is a key factor in the success of dental implants.
