Cohesive gel implants are a new type of silicone gel implants which have a superior ability to maintain its shape. These implants are commonly known as "gummy bear implants" because the material used to fill the implants has a feel and consistency very similar to the popular candy known as Gummy Bears.
The disadvantages to these types of breast implants are largely related to the surgical procedures. Specifically, a transumbilical breast augmentation is not possible with cohesive gel implants. The method involves folding the implant and inserting it through a long narrow tube. Furthermore, these types of breast implants have procedures that require longer incisions than procedures involving saline or silicone implants because the cohesive gel implants hold their shape so well and cannot be compressed easily.
