What would happen if you went over your breast implant maximum CC?

 I’m  not sure I am in total agreement with the other doctors. If an implant is designed to hold 300 mL to 330 mL, and the doctor puts in 340 mL… Not much happens. It’s a little more full and it does not void the warranty. In fact my knowledge going over there till volume never voids the warranty only going under. So it is common practice still to overfill slightly in many cases but too much overfill causes the implants to be very tight,  more like a ball, and wrinkle on the side. 

Maximum implant size is less a function of volume and more a function of base width. You are limited by the space of your chest and the footprint of the breast mound when selecting implants. Exceeding these measurements typically results in malposition of the implants (migration into the armpits).Excessive sizing is also associated with a higher risk of complications and decreased longevity of result (not to mention less satisfying aesthetic results i.e. the "fake" look).As always, discuss your concerns with a board certified plastic surgeon (ABPS).
