Curly Blonde Girl Shows Off Her Silicone Breast Implants On The Couch At Home

As a medical device technology, there are five (5) generations of silicone breast implant, each defined by common model-manufacturing techniques.
- First generation
The Cronin–Gerow Implant, prosthesis model 1963, was a tear-drop-shaped sac (silicone rubber envelope) filled with viscous silicone-gel. To reduce the rotation of the emplaced breast-implant upon the chest wall, it was affixed to the implant pocket with a fastener-patch of Dacron material (Polyethylene terephthalate) attached to the rear of the breast implant shell.
