What material are most eposteal (subperiosteal) implants made of?

Most eposteal (subperiosteal) implants are made of titanium due to its excellent biocompatibility, strength, and resistance to corrosion. Titanium is a lightweight metallic element that has a favorable interaction with human tissue, promoting osseointegration, which is the process where the bone grows around and integrates with the implant, providing optimal stability and durability.

The use of titanium also minimizes the risk of rejection or allergic reactions compared to other metals. Additionally, titanium can be easily shaped to fit the specific anatomy of the patient, further enhancing the functionality of the implant. This combination of properties makes it the ideal material for dental and orthopedic implants, ensuring longevity and effectiveness in support of dental prosthetics.

Other materials like stainless steel, plastic, or gold do not offer the same level of performance or biocompatibility. Stainless steel may corrode over time and is less suitable for long-term implantation in the bone. While plastic can be used in some dental applications, it lacks the necessary strength for structural support in an implant setting. Gold, although biocompatible and historically used in dentistry, is not practical for the structural demands of subperiosteal implants. Thus, titanium remains the material of choice for such applications.
