Silicone is one of the most suitable materials for human body. There are 3 types of silicone implants such as solid, gel and liquid implants. Liquid implants were banned in 1996 due to its high risks.
One type of silicone implants is that has silicone outer surface and filled with physiological saline solution inside. The other type of silicone implant is that have gel compound inside. Those that have physiological saline solution may lose certain amount of volume through time. Whereas gel filled silicone implants do not lose that much volume. Recently “cohesive gel” filled implants have become very popular which do not lose any volume nor shape.
