Smooth Round Moderate vs. Smooth Round Moderate Plus

At my consult last year, I chose to get silicone implants placed under the muscle, incision in the crease, but still not too sure yet of profile shape. What are the differences in final look and results between smooth round moderate and smooth round moderate plus? I want 500cc but i've read that under the muscle placement somewhat "flattens out" implants; because of this reason would it be best to choose 550cc so that the final result will look like a 500cc? Thank you in advance.

Moderate versus Moderate Plus Implants: Whats the difference ?

Hello and thank you for the question.

In general when comparing a moderate and moderate plus implants, volume per volume, the moderate plus implant will offer slightly greater projection than will the moderate implant, which alternately, offers greater width. The premise that a sub-muscular implant placement will give you a "flatter" look is pure fallacy. As my colleague was suggesting, if done properly, the sub-muscular pocket will accommodate your implant perfectly with no compromise in projection. In my practice, the Mentor Moderate Plus Profile implant is the preferred choice, with the exception of women with narrow chests that are better suited for high-profile implants.

Difference between moderate and moderate plus

The difference is not much.  It is actually a few millimeters in projection.  If you are looking for a fuller look, then go with moderate plus or high profile.  If you are looking to stay more conservative, then a moderate plus or moderate may do the trick. I consider two factors when selecting implants for my patients: 1.Dimensional planning 2.Gel Implant Sizing system Dimensional planning – The measurements of your chest wall are taken. Also, the breast dimensions including the height, width, and current dimensions of each breast form the basis of dimensional planning. Based on these measurements, the implant size is recommended. This will give you a unique breast implant that is suited for your body frame. Even your fitness levels and other relevant criteria are taken into consideration. It is you who will decide what you are comfortable with. Gel Implant Sizing system – During the preliminary breast implant consultation, you will be provided with an option to “try on” a variety of implant shapes and sizes. You can also visualize the possible outcomes of your surgery which helps you to get that perfect size to give you the shape that you longed for. This way your preferences are known and we can then pick a range of implants that will “fit” just right to give a soft natural fuller look.  Hope this helps.

Smooth Round Moderate vs. Smooth Round Moderate Plus

I agree with the volume but I prefer HP. So I guess I added more issues. From MIAMI Dr. Darryl j. Blinski

Moderate versus Moderate Plus Profile Saline Filled Mammary Prosthesis

Under the muscle placement will procduce a loss of implant projection comparable to losing 10-15% of the volume of the sizer placed over the breast when sizing preoperatively. I prefer the moderate plus for increased projection and less rippling.

Very little difference in a moderate and moderate plus implant

There is very little difference between a moderate and moderate plus breast implant and it is very unlikely that anyone could tell the difference after a breast augmentation. If implants are placed and covered well neither should present problems with rippling. Also, the submuscular placement of an implant will not flatten out the result or make the breast look smaller.

Best of luck,

Implant choices

Implant options today are much better than they were years ago.  As for the  moderate plus vs moderate the main difference is that for the same volume, the moderate plus are narrower and have more projection.

Moderate plus has slightly more projection

The implants are mentor type implants, and the moderate plus will have slightly more projection and slightly smaller diameter for a given size. Your surgeon will measure your chest diameter and take your goals into consideration when chosing the implant, however I agree that the difference between the two should be minimal.

"Flatten Out" of Implant Under Muscle Just A Myth

One of the great myths out there is that the muscle will flatten theimplants and make it appear smaller when underneath the muscle.  This is just a myth.  When done correctly, the muscle should stretch just like the skin, and therefore be just as loose and soft.  If it wasn't, the implant would be tight and feel firmer.  If it is nice and soft, and sits in the appropriate space, then in should be the exact same size as over the muscle.  With regards to the type of implant, I use the moderate plus implant 80% of the time.  I think it does a better job of giving women both the size and the projection.  For the same width, the moderate give you 1.5cm less projection. It doesn't sound like a lot, but if you had a 500cc moderate on one side and a 500cc moderate plus on the other, ytou would be able to tell.  In your case, i wouldgo with the 500cc moderate plus implant.  I hope this helps.

Mentor Moderate vs Moderate Plus Breast Augmentation

There are quite a few differences in the implants.  Ideally you want a breast implant that fits your natural tissue pocket.  That the major difference between moderate, moderate plus and high profile implants.  The plus and high profile implants have  smaller diameter base but more projection.  If you have a very slight frame then the moderate plus and high profile tend to give a nicer result without rubbing on you arms or getting too close to the midline.

Generally I have my patients pick a volume based on cup size, then I will pick the diameter based on their breast and chest measurements.  That gives the most natural look with the least complicationds.

Difference between Moderate and Moderate Profile Plus

I agree that there is minimal difference.  There is slightly more projection with the Moderate Profile Plus.  Also, a 50 cc difference is not much.  It is best to go over the different options with your surgeon so that you are well informed before surgery and to make sure the surgeon understands your expectations and concerns.  


Good Luck.
