Implants are medical devices that are placed inside the body to replace or support damaged biological structures. They can be made from various materials, such as metal, plastic, or ceramic, and are commonly used in procedures like dental implants, joint replacements, and breast augmentation. Implants are designed to integrate with the body and can improve function or appearance. There are different types of implants, including dental implants, which replace missing teeth, and orthopedic implants, used to support bones and joints. The success of an implant often depends on factors like the patient's health, the type of implant, and the surgical technique used.
