Implants

In medical practice, an implant is a prosthesis used to change the shape and contour of a person's body. In reconstructive or cosmetic surgery, implants can be employed to restore a natural physical appearance following a critical injury or to enhance the existing physique through augmentation surgery.

There are four general types of implants, defined by their filler material: saline solution, silicone gel, structured and composite filler. The saline implant has an elastomer silicone shell filled with sterile saline solution during surgery; the silicone implant has an elastomer silicone shell pre-filled with viscous silicone gel; structured implants use nested elastomer silicone shells and two saline filled lumen; and the alternative composition implants featured miscellaneous fillers.
