What materials are commonly used in the construction of dental implants?

Titanium and zirconia are the primary materials used in the construction of dental implants due to their excellent biocompatibility, strength, and corrosion resistance. Titanium, in particular, is favored because it has a long history of successful use in implants, promotes osseointegration (the process by which bone integrates with the implant), and is generally well-tolerated by the body. Its ability to form a strong bond with bone makes it ideal for achieving stability and longevity in dental restorations.

Zirconia, on the other hand, offers a tooth-like appearance and is often chosen for esthetic reasons, particularly in anterior (front) teeth restorations. It is also biocompatible and provides good mechanical properties. The combination of titanium’s established reliability and zirconia’s favorable aesthetic qualities makes them a popular choice among dental implant materials.

In contrast, materials such as zinc and aluminum do not provide the same level of biocompatibility or mechanical properties necessary for dental implants, making them less suitable. Similarly, while gold and silver have historical significance in dentistry, they do not possess the unique properties required for successful dental implants compared to titanium and zirconia.
