Will 450cc HP Silicone Gel Implants Unders Make Me into a Full C/ Small D?

At size 34 each 100 cc's of implant corresponds to 1 cup size change.  Since you are a 34 A and want to be a D, 300 cc's would be adequate.  I recommend silicone gel placed retro-pectoral since they look and feel more natural and are less likely to ripple.  I do not believe you can accommodate 450 cc under the muscle and they will extrude inferiorly and laterally and you will require revisions.  The goal of breast surgery is to achieve beautiful breasts.  Beauty is determined by skin tone, symmetry, cleavage, position on the chest wall and least of all volume.

In general, silicone implants are much less likely to cause rippling than are saline breast implants.  Unfortunately without an exam, I cannot accurately predict your final size or your risk for rippling.  I recommend that you try on the breast implant sizes that you are considering in your surgeon's office prior to surgery so that you can make sure that this is the right size for you.  Good luck.

Thank you for your question.  This is a common question and area of angst with patients.  Yes, a 450HP silicone will generally get you to a C/D with your current chest size.  As others have stated, more important that the actual cc's of the implant is the dimension or width of the implant and how this will fit on your chest or within the "footprint" of your breast.  If the implant width is wider than your  breast width, then the implant will tend to hang over the side of your chest, where you rub your arm against the side of your breast.   This can give a very different look.  Ultimately, the size of the implant should not only be based on your goal cup size, but also on the dimensions of your breast and the "look" you are going for--whether you want a more natural look or an augmented look.

Good luck!

 

450 cc implant is a large breast implant, and you may be able to achieve your goal with a smaller implant. However, the size of the implant generally does not correlate to the frequency of rippling. The size of the implants are based on a combination of a patient's goals
and objectives and her anatomy. In order to provide a natural looking
augmentation, the surgeon needs to evaluate many factors including soft
tissue coverage, skin laxity, chest wall width, breast imprint width,
the shape of the breasts and relative level of constriction to ensure
that the breast implants are appropriate for your body. Consult in
person with 3 experienced and expert board certified plastic surgeons to
understand your objectives.

I do not think implant size with silicone will affect your chance of rippling.  In order to make an accurate size recommendation, I would need to assess your chest wall and breast mound measurements and characteristics.  Unfortunately, there is not a general rule of thumb or objective criteria to implant selection.

Your plastic surgeon will perform several measurements of your chest wall and breast anatomy and determine a range of implants that both fit your chest wall and reach your desired goals.
The next step is to try on this range of implants in the office with your doctor.   The key to this success is showing your surgeon the body proportion you desire with a bra sizer and allowing your surgeon to guide you to the right implant.   It will be much easier to communicate in implant cc's than cup size when determining the appropriate implant for you.
I wish you a safe recovery and fantastic result.
