Advice on Mentor vs Motiva?

It is very difficult to determine the best lift you will need (recommended based on your photos) or the exact size and shape implant you will require to best match your ideal breast image without an examination by a board certified plastic surgeon. Not just any board certified plastic surgeon, but one with many years of frequently performing breast augmentation surgery including different approaches, techniques and implant choices. This is because several measurements not to mention your breast characteristics are needed to determine the optimal implant size to obtain your goals. Without knowing these dimensions it would be difficult to make this determination. For example, the existing base width of your breast will determine, in many cases, the maximal volume per implant profile that you can accommodate. To illustrate; a 100 cc difference may make a significant difference with a narrow base width breast, but much less of a difference if you have a wide chest wall and wide breast “foot print”. Therefore, just because your friend may have a great result with let’s say a 300 cc implant to make her go from a “A” cup to a “C” cup size does not mean that you will have the same result with the same size implant. The same process goes for just filling in the upper part of your breast without becoming much larger. Further simply placing implants in a bra to determine the size best for you is not always accurate as the bra often distorts the size, is dependent on the pressure the bra places plus the implant is outside your breast and not under it among other variables. Computer software morphing programs that automatically determine the best implant size can be helpful in some but not all cases (e.g. doesn’t work well in my experience with existing implants, sagging or asymmetric breasts). Using “want to be” photos however are useful if simply provided to the surgeon as I will further explain in the link below including silicone vs saline implants

The important decision in choosing a breast implant size is a proper fit of the implant based on your personal measurements and the profile that will give you the upper pole look you want- more natural or more implanted.Each manufacturer has a catalog of available sizes and your surgeon should be offering you the implant that fits most appropriately for the look you desire. Mentor is a long standing implant manufacturer with FDA approval for use in the US. They offer warranties on rupture and capsular contracture.  Motiva is currently FDA approved for use in the US, so I have no experience with them and I cannot comment on their catalog and sizing.On Motiva, I would suggest you ask about warranties and I think it likely you will be asked to sign some sort of release that says you realize they are not FDA approved for use in the US.  

Than you for submitting this question.  It appears that there are two issues that you are asking about, the appropriately sized implant and which manufacturer's implant to use.  The second question is much easier to answer than the first.  You should only choose FDA approved implants, regardless of the popularity of various other implants throughout the world.  There are several other manufacturers of FDA approved implants besides Mentor, so you and your surgeons do have additional choices if you feel that you need them.  The second question, what would be the appropriate sized implant to use can only be answered by examining you in person.  I suggest that you see a Board Certified Plastic Surgeon who is experienced in performing breast augmentation for a consultation to help you determine what size and style of implant would be best for you.

Implant size is a key determinant for patient satisfaction after surgery.I like to utilize computer imaging so the patient can get an understanding based upon their own body the implication of specific implant sizes.As far as the implant companies one is synonymous with quality and the other is a total unknown but a little less expensive.
