To understand this, let’s go back several decades and look at this implant. It was called the Replicon. The positives and negatives of this implant were exactly what inspired the creation of cohesive implants in the early 1990s.

The Replicon was a polyurethane coated implant (they are no longer available in the United States because the polyurethane could cause a cancer in rats that humans do not get!) The implant also had an anatomic shape, so that it was thin and tapered at the top and had more projection at the bottom, just like a natural breast. Because of the thickness of the polyurethane, the implant felt very form stable in your hand when you felt one outside of the body. It maintained its shape and it did not collapse or fold.

The initial results with the implant were wonderful. It gave breasts a lovely shape and they felt very soft.
