All About Overfilling and Underfilling
Overfilling Breast Implants
Implants come in a wide range of sizes. Except for pre-filled implants, all breast implants have a fill amount that is recommended by the manufacturer. For example:
The Mentor smooth round 300cc implant can be filled to (f/t) 325cc. 325cc is the maximum amount of cc's recommended by the manufacturer. 300cc is the nominal fill amount recommended for that particular implant size. See the
Implant Specifications page for more information.
If your doctor fills the implant past the point of the manufacturer recommendation, this is considered "overfill". Overfilling (depending on the amount) makes the implant feel firmer, and doesn't provide any distinguishable size difference.
It is very important to remember that overfilling the breast implant gives the implant manufacturer the right to void the
warranty in the event of a rupture. If your doctor is going to overfill your breast implants, it's advisable to have your doctor put it in writing that he will cover the associated costs (those that would be covered by the warranty, in the event the manufacturer voids it) of replacement if the implant fails.
Overfilling may also INCREASE your risk of having visible and/or palpable ripples.
Underfilling
Breast Implants
If the implant is not filled to the minimum recommendation, it can get folds in it, which can jeopardize the integrity of the implant, possibly causing it to rupture. The constant "rubbing" of the fold can lead to rupture. Visible
ripples are also more common in implants that are not filled to the minimum recommended amount, depending on the amount of breast tissue you start with.
In other words, if you have a Mentor 300cc size implant, you will want it filled to a minimum of 300cc, nothing less, and preferably, no more than 325cc, which is the optimum fill level recommended by Mentor.
Underfilling may also void the manufacturer's warranty, especially if there is a rupture.
