Dental implants are usually made out of which material?

Stainless Steel
Titanium
Cobalt-chromium alloy
Plastic polymer

The correct answer is: Titanium

Dental implants are primarily made from titanium due to its excellent biocompatibility, strength, and ability to undergo osseointegration, which is the process where the bone grows around the implant, providing stability. This material allows the implant to integrate effectively with the jawbone without being rejected by the body, making it an ideal choice for long-term dental solutions. Titanium also has a lower weight compared to metals like cobalt-chromium alloy, yet it maintains a high level of corrosion resistance which is essential as the implant is placed in an environment that can be affected by moisture and temperature changes within the oral cavity. Stainless steel, while strong, is not commonly used for implants due to its potential for corrosion and less favorable biological properties in terms of long-term stability and integration with bone. Plastic polymers may be utilized in other dental applications, but are not suited for the structural demands of implants due to their lower strength and durability.
