Does a 225 cc saline implant look the same size as a 225 cc silicone implant?

The use of the same volume saline versus silicone gel breast implants may achieve a  modestly different outcome.    In my experience, silicone gel breast implants tend to conform to the chest wall;  the resulting appears slightly more “natural”,  and may appear smaller. On the other hand, saline breast implants tend to provide slightly more projection;  they may achieve a look that is less “natural”, and may appear larger. Of course, much of the outcome achieved with breast augmentation surgery will depend on how much breast and soft tissue coverage the patient possesses naturally. I hope this, and the attached link (dedicated to breast augmentation surgery concerns) helps.

Saline and silicone look pretty much the same.  If a saline implant is "overfilled", meaning the a smaller implant is filled to a higher capacity, the implant can look and feel different.  But assuming the shell is the same and the same amount of saline or gel is in the implant, the implants are the same size.
