“Gummy Bear Breast Implants” have the consistency of gummy bears. This means there should be no folding or rippling. Being more formed should presumably allow the implants to maintain a shape closer to the original post-operative contour. Finally, should the implant rupture, migration should not occur to the same degree as with older generation implants.
The main disadvantage to the cohesive “gummy bear” implants is that they require a somewhat larger incision to place. Being more formed does not allow for the kind of manipulation and squeezing through a tight incision that is possible with the older, more liquid-like silicone breast implants. The other drawback is that the gummy bear breast implants only come in the “teardrop,” contoured, or shaped variety in the U.S.
