Sientra offers two different FDA-approved silicone gel breast implant options: round implants and teardrop-shaped implants.Â
Both come in a variety of sizes, projections (how far forward they protrude from the chest wall), and surfaces (textured or smooth), to suit different body proportions and desired results, from a very natural look to a more dramatic enhancement.Â
They’re also available in two types of highly cohesive silicone gel.
Cohesiveness, often explained as “gumminess,” refers to the silicone gel’s level of firmness—a result of how the silicone molecules are bonded. All Sientra breast implants are considered “gummy bear” implants (“form-stable” or “highly cohesive,” in medical language). This firm yet pliable form of silicone gel bounces back to its original shape after being touched, like gummy bear candy.Â
Highly cohesive silicone gel implants were once thought to carry less risk of gel leakage and rippling, but this belief has not been supported by data, according to Dr. Kamakshi Zeidler, a plastic surgeon in Campbell, California. “The studies show equal rupture rates.” Dr. Zeidler also notes that “firm implants do not necessarily look or feel less natural,” another common myth about cohesive gel implants.
Sientra implants are approved for breast augmentation patients who are at least 22 years old, as well as for breast reconstruction patients of any age. They’re available only through board-certified plastic surgeons.Â
Sientra’s round implants are available in:
- six projections: low, low plus, moderate, moderate plus, high, and “Xtra” high
- two surface types: microtextured or smoothÂ
- two types of silicone gel: HSC (high-strength cohesive) and the slightly firmer HSC+
This cohesiveness provides shape retention and fullness, especially in the upper pole (the area above the nipple).
Teardrop-shaped Sientra implants are filled with HSC+ silicone gel and have a lightly textured surface, which is thought to help maintain the position of the implant. They come in:
- two base shapes: the classic (curved) base and a round base
- a wide variety of widths, heights, and projections, to help customize your result
Teardrop-shaped implants provide a natural look on patients with minimal breast tissue, as the tapered top can blend into the appearance of the chest wall. Â
RealSelf Tip: Sientra round gel implants were approved for distribution in Canada in summer 2022, making Sientra the third silicone gel breast implant manufacturer to be approved for use there.
