Dental implants are an example of which material category?

• A. Metals
• B. Ceramics
• C. Polymers
• D. Composites

Answer: (B)

Dental implants are often made from zirconia, a ceramic material. Ceramics in dentistry are valued for their biocompatibility, chemical stability in the mouth, and tooth-like appearance. Zirconia implants avoid the metallic look under gum tissue and offer excellent hardness and wear resistance, which suits long-term function in the jaw. While metals such as titanium are also used for implants because of their strength and ability to integrate with bone, the ceramic category is a common and important option for implants, making this a ceramics example.
