The Form-Stable Silicone Breast Implant

A year ago Sientra was the first company to receive FDA approval for a new type of silicone gel implant. Now one more has received the FDA’s nod: Natrelle’s Style 410 shaped implant from Allergan. Sometimes called “gummy bear,” “form-stable,” or “highly cohesive silicone gel,” these implants are designed to maintain their original form.

How are Gummy Bear Implants different from other silicone gel implants? It all has to do with an increase in the cross-linking of the silicone molecules. Studies from both companies indicate that this increased cross-linking may lead to lower rates of hardening (“capsular contracture”). The implants are firmer which helps them maintain their tear-drop form. These shaped implants come in a variety of different dimensions to accommodate many different builds. The shaped implants? ability to maintain their form can help improve not just the size of a woman’s breasts, but the shape as well.

    With Lots of research and discussion I chose to have these implants. I am so happy with my choice. They feel natural and I am so glad they had this option when I had my surgery at Plastic surgery associates.
