What is a disadvantage of using implants inside the body?

A significant disadvantage of using implants inside the body is the risk of infection, which can occur during the implantation procedure or afterward. Additionally, the body may react negatively to the foreign material, leading to inflammation or rejection, which could compromise the implant's functionality. Long-term complications such as implant failure or the need for replacement surgeries can also arise, adding to healthcare costs and patient discomfort.
