Types of Breast Implants

One search says silicone. Another says gummy bear. A third says round, smooth, high profile. It can sound as though you're looking at six different categories of implant when some of those words describe the very same device.

You don't need a favorite brand before your first consultation. Start by getting comfortable with the vocabulary, then let your surgeon explain which combinations fit your anatomy and goals.

A quick map of the terms

For example, an implant might be a smooth, round silicone gel device in a particular profile and volume. Each word adds a different piece of information.

Silicone gel implants

Silicone implants contain silicone gel inside a silicone elastomer shell. They arrive prefilled, with their volume and dimensions specified by the manufacturer.

Gels differ in how they move, compress, and hold their shape. Cohesive means the gel holds together; form stable describes how it retains its shape. Terms such as Responsive may also be product names, so check the manufacturer's description of the specific implant.

If feel is a priority, ask to handle samples. Then ask how your own tissue coverage and the placement plan may affect the feel of the breast after healing.

A sample helps explain the device. It can't reproduce the sensation of the device covered by living tissue.

Saline implants

Saline implants use sterile saltwater as the fill and still have a silicone shell.

Many saline devices are filled during surgery within a specified range. The surgeon follows the labeling for that device; the range doesn't mean it can be filled to any volume the patient chooses.

If the implant loses shell integrity, saline can leak out and the breast may visibly lose volume. A clinician should assess the change and discuss treatment.

The FDA explains the basic materials and US age indications for saline and silicone devices. Exact labeling and eligibility should be reviewed for the implant being considered.

Structured saline implants

Structured saline devices use internal components to manage the saline's movement and support the device's form.

Serene is a structured saline option whose chart separates the empty implant volume, inner fill, outer fill, and total device volume. This makes its sizing information a little different from a standard prefilled gel chart.

Structured saline is still saline-filled. It isn't silicone gel with a different name.

If you're curious about it, ask your surgeon to compare actual samples and explain the construction, available dimensions, follow-up, and any considerations specific to your tissue. Serene device information.

What gummy bear means

“Gummy bear” is an informal term commonly used for cohesive silicone gel implants.

It can suggest that the gel holds together more than a liquid would, but it doesn't identify one standardized implant, gel formulation, profile, or brand.

Two devices called gummy implants may differ in firmness, dimensions, and fill characteristics. A demonstration of a cut implant outside the body also can't show everything about its performance in a patient.

Ask for the product name and the manufacturer's explanation of its gel. The gummy implant guide goes into those distinctions.

Round and anatomical shapes

A round implant has a round base. An anatomical implant has a deliberately shaped form, often described as teardrop.

The device's shape is different from the final shape of the breast. A round device doesn't require a visibly round upper breast in every patient. Tissue, position, gel, size, and surgical technique contribute to the appearance.

An anatomical device also needs its orientation considered as part of the plan. Availability and surface options vary by product and country.

Ask which specific device your surgeon means when discussing a shape. A photograph of the implant on a table can help explain its construction, while clinical examples provide a different kind of context.

Smooth and textured surfaces

Surface describes the outside of the shell. It doesn't tell you whether the implant contains saline or silicone gel.

Surface choice requires a product-specific discussion. BIA-ALCL, a lymphoma associated with breast implants, occurs more commonly with textured devices. The FDA's questions and answers explain this association.

Some older textured products have been recalled. A historical catalog, a regulatory approval, and a currently available device are therefore different things.

You don't need to sort out every surface terminology debate by yourself. Ask your surgeon for the exact device labeling and the reason for the proposed surface.

Profile and volume

Volume is the number in CC. Profile describes the relationship between width and forward projection within a product system.

At similar volumes, a higher-profile device will generally be narrower and more projecting than a lower-profile device in that range. At similar widths, a higher-profile option will generally have more volume and projection.

Names differ between brands. Use the actual dimensions when making a comparison.

This is why “small implant” and “low profile” aren't interchangeable. One describes an amount of volume in context; the other describes a device category.

Brand names are another layer

A brand is the manufacturer identity you recognize. A product family is a particular range under that brand. A model code identifies a more specific device.

The US labeling directory includes devices associated with Mentor, Natrelle, Motiva, Sientra, and Serene, including former names. FDA labeling directory.

That directory is a useful reference, but it doesn't establish what every surgeon stocks or which historical product remains sold. Confirm the proposed device and current availability during your consultation.

Put the description together

By the time you have a shortlist, you should be able to describe each option in one sentence.

For example: “We're considering a smooth, round silicone gel implant from this family, with this profile, volume, width, and projection.”

Then add the reason: “My surgeon recommends these dimensions because…” If that explanation still feels unclear, ask them to walk through it again.

The most helpful type of implant is the specific device you understand in the context of your own plan. Learning the categories gives you a comfortable place to start that conversation.
