Body implants are medical devices placed inside or on the body to support or enhance its function. Common types include pacemakers, which help regulate heartbeats, and joint implants, used to replace damaged joints. These devices can improve quality of life for individuals with various health conditions. Implants can be made from materials like metal, plastic, or ceramic, and are often used in surgeries. They may be temporary or permanent, depending on the purpose. Advances in technology have led to the development of biodegradable implants, which dissolve over time, reducing the need for additional surgeries.
