Biomedical implants are medical devices placed inside or on the surface of the body to support or enhance biological functions. They can be made from various materials, including metals, ceramics, and polymers, and are used in a wide range of applications, such as joint replacements, dental implants, and cardiac devices like pacemakers. These implants are designed to integrate with the body and can help restore mobility, improve health, or replace damaged tissues. Advances in technology have led to the development of smart implants that can monitor health conditions and deliver medication, further enhancing their effectiveness in patient care.
