A gummy implant is a very firm version of a silicone implant. It is heavier than other implants. It is primarily intended for rebuilding or reconstruction after cancer surgery. Many patients prefer a softer, more natural feel than a gummy implant. Some patients like the fact that the rigidness of the gummy implant provides the same contour regardless of whether you are standing, leaning over or lying down. Gummy implants (being fairly rigid) will bounce and move differently than softer implants. Some people prefer the bounce of a gummy, and some people prefer the bounce of a natural breast (one without implant) or softer breast.
