Saline is simply salt water. A saline-filled implant can provide excellent results and is very easily monitored. A saline-filled implant has the characteristics of a water balloon. Patients can sometimes experience rippling and show-through with this implant if they are slender or don’t have a lot of existing breast tissue. Silicone gel-filled implants are more natural looking and feeling than saline-filled implants. They are more ‘forgiving’ in terms of adding volume to a patient who doesn’t start with a lot of her own breast tissue. The latest technology in gel implants, referred to as the”gummy bear implant” due to its solid filler, provides excellent results with its anatomically-shaped composition.
