Medical implants are devices placed inside or on the body to support or enhance bodily functions. They can be made from various materials, such as metals, ceramics, or polymers, and are used in a range of applications, including orthopedic surgery, dental procedures, and cardiac support. Common examples include pacemakers, hip replacements, and dental implants. These implants can be temporary or permanent, depending on their purpose. Some are designed to help heal injuries, while others may replace damaged tissues or organs. Medical implants are often used to improve the quality of life for patients and can significantly aid in recovery and rehabilitation.
