Biomedical implants are medical devices that are surgically placed within the body to replace a missing biological structure, support a damaged biological structure, or enhance the function of an existing biological structure. These implants are commonly used in orthopedic, dental, cardiovascular, and ophthalmic surgeries. They can be made from a variety of materials such as metals, ceramics, and polymers, and are designed to be biocompatible to ensure they do not cause harm or rejection by the body. The field of biomedical implants is constantly advancing with new technologies and materials being developed to improve the performance and longevity of these devices.
