Mentor Implant Size Chart Guide

A Mentor sizing chart becomes much easier to use once you know exactly which family and profile you're looking at.

The table below gives a selected set of manufacturer-listed MemoryGel examples. It is a reference for understanding the measurements, rather than a complete catalog or a personal sizing recommendation.

Selected MemoryGel dimensions

These entries appear in the Moderate Classic section of the manufacturer's US product information reviewed for this draft. Model identifiers are reproduced in the format shown there.

Source: Mentor US MemoryGel ordering information, accessed November 4, 2026. These are selected catalog entries, not a statement of current stock. Confirm specifications and availability for the proposed device with the treating practice.

What this table shows

Read across a row before comparing it with another.

The listed 300cc example has a diameter of 12.8cm and projection of 3.1cm. That describes this specific device. It doesn't mean every Mentor 300cc implant has those dimensions.

The next selected entry is 320cc, with a diameter of 13.0cm and projection of 3.2cm. In this comparison, volume, width, and projection all change.

The volume difference is 20cc. The diameter difference is 0.2cm. Neither number alone establishes how noticeable the change would be after surgery.

This is why the chart and your examination need to be considered together.

What the model code adds

The model identifier helps distinguish products whose names sound very similar.

Keep the complete code in your notes, including letters and any punctuation used on the official device label. It is safer to copy it than to reconstruct it from the volume.

Your device card and operative record should identify what was actually implanted. A consultation note may instead describe proposed options, so keep those records distinct.

If you're researching someone else's case, a full model code adds useful context. If it isn't available, avoid assuming the profile from the CC number.

Why the profile matters

Within a product system, different profiles distribute volume differently across the base and forward projection.

The selected Moderate Classic entries above don't represent Mentor's entire profile offering. Other profiles and families need their own chart sections.

If your surgeon recommends a narrower, more projecting option, ask to see its actual row beside the alternative.

You may be comparing similar volumes with different widths, or similar widths with different volumes. Knowing which comparison you are making is more helpful than choosing a label alone.

Xtra and BOOST require their own specifications

Don't carry dimensions from a MemoryGel row over to an Xtra or BOOST device with a similar volume.

Those families have different design features and their own specific models. Ask the practice for the current manufacturer chart for the devices on your shortlist.

The Mentor family explainer helps separate those design questions from profile and volume.

A useful comparison card includes the product family in the first column, so the numbers never lose their context.

A chart can't prescribe breast width

It is tempting to measure across your breast at home and choose a matching row.

A surgeon's assessment includes breast width, how much tissue covers the implant, skin stretch, the breast crease, and chest shape. An external tape measurement doesn't capture all of that.

Ask your surgeon how they interpret your measurements and why a particular device width is appropriate.

Use the chart to understand the explanation, rather than trying to replace the examination with a lookup.

Can this chart tell me my cup size

No. The entries describe devices, while bra fit depends on your starting volume, chest dimensions, final breast shape, and the bra itself. Use a cup-size preference to begin the conversation, then add photos and a description of the fullness you want. The surgeon can connect that preference with the devices that fit your examination.

How to bring the chart to your consultation

Choose the rows your surgeon has recommended and write a question beside each one.

For example: “Why this width?” “What would I notice from the side?” or “Does this option change the placement or need for a lift?”

If you have two different implants planned for asymmetry, keep a separate left and right entry. Don't rely on memory to match the device to the side.

Before surgery, confirm the chosen device or agreed range of alternatives and how any final decision will be made.

A useful outcome from chart research

You don't need to know every model in the catalog.

You should be able to identify the options being discussed, understand what the measurements mean, and ask how those measurements relate to your goals. That is enough to turn a dense table into a helpful part of your planning.
