Traditional Silicone v. highly cohesive form stable silicone (”Gummy bear”)
Technically all silicone devices are “cohesive.” The degree of “cohesivity” can range from minimal (more like liquid) to extreme (more like a solid). The Allergan style 410 and the mentor CPG are highly cohesive form stable silicone devices. These devices have increased cohesivity as compared to the current FDA approved silicone gel devices. It is this increased cohesion that allows for the device to be shape and form stable. These devices have the consistency or feel similar to a “gummy bear” candy and are frequently referred to as such on the internet.
Highly form stable silicone devices are available as part of ongoing FDA studies for primary augmentation and reconstruction. Though they have been in use since 1994 and are currently without restriction in Canada, Australia, and Europe it is still uncertain when they will be approved by the FDA and there are a limited number of surgeons in the United States who are participating in those studies. There are two separate trials for the Allergan style 410 (gummy bear) device, one for patients that have never had implants and another for those undergoing breast reconstruction or who desire removal and replacement of their current implants.
When looking objectively at the data and the “trade-offs” of all the devices (saline, traditional silicone, and highly cohesive for stable gel) there are some potential advantages for some patients with the form stable devices. Particularly for breast reconstruction, as well as for those breast augmentation patients with thin soft tissue cover who desire a very natural result. If you are interested in a gummy bear device seek out a plastic surgeon that will review the options and trade-offs after taking your history and listening to your desires and expectations. An examination and careful measurements of your breast and chest dimensions and tissues are important in the decision making process.
