Differences Between Memory Gel and Cohesive CPG Mentor Implants

What are the differences between the Memory Gel and CPG Cohesive gel implants? Is it true that the CPG is thicker and stronger and will retain shape better and makes for a firmer implant than the FDA approved Memory Gel? Thank you.

Memory gel, CPG cohesive gel (gummy bear implants)

Silicone gels can be fabricated with differing degrees of cohesiveness or viscosity. These will determine the qualities of the silicone gel implant. To simplify this the some individuals refer to the generation of the implant. Current implants are considered the third generation. Among the third generation implants there are 3 degrees of increasing thickness. The first type is generally labeled the "memory gel" by Mentor corporation. The second type is no longer available and... more

Cohesive gel versus memory gel

Cohesive gel implants are the "Gummy" implants that are firmer. They need a larger incision for palcement and if they rupture will not ooze. The memory gel implants are the standard gel implants that will feel more natural.

Memory Gel implants are softer than CPG implants

Hi there- As stated by my colleagues, the memory gel implants are less polymerized, so the silicone gel is softer than the solid CPG implants. Having said that, they are still highly polymerized, and so retain their shape very nicely... Furthermore, because they are softer, it is my opinion that they provide a more natural result (at least in augmentation patients). I hope that helps.

Cohesive breast implants

The Memory Gel is a cohesive implant, but the CPG is firmer and more cohesive. If you were to cut this implant, it would hold its gel, in the same way that a cut gummy bear holds its gummy (hence the term "gummy bear implants"). These do feel firmer than regular silicone implants. The shape is a tear-drop, which is very useful for breast reconstruction after cancer, and in other situations where the patient needs more fill in the upper part of her breast. These implants are... more
