An implant is a device or material that is placed inside the body to improve bodily function, deliver medication, or for other purposes. These implants can be made of various materials like metal or ceramic, and they are used in a wide range of medical procedures. Examples include joint replacements, dental implants, implants to prevent pregnancy, cardiac implants, and hearing implants. The goal of implants is to improve or restore function in the body, support healing, or provide long-term medical treatment. They are carefully designed to work well with the surrounding tissues without causing harm or discomfort.

Surgery is a medical procedure where a doctor makes a cut to treat or remove parts of the body, repair injuries, or address health issues. It can involve various techniques, such as cutting, stitching, or using specialized tools, and is often performed in a hospital or surgical center. Surgery can be planned in advance or done as an emergency procedure and usually requires anesthesia to ensure the patient does not feel pain during the operation.
