There is not one answer for this question. Silicone implants do feel more natural than saline, but size, shape of implant, position of implant and placement all make a significant difference in the final result. Many women believe that breast augmentation is a straightforward surgery and if they know the size of implant, the placement and the material, that any surgeon can provide the result they see in a before and after gallery. That simply isn't true. Breast augmentation surgery is a complex surgical procedure that takes time, experience, patience and exceptional training if the results are beautiful and natural consistently. A beginner cook and a master chef could take the same recipe and end up with completely different results. On occasion, the beginner cook will have a "home run" but consistently great results come from training, experience, patience and care. Take your time, do your research, look for consistently great results and find the plastic surgeon with the best training. You are making a permanent change to your appearance. Do all you can to make it the best the first time around.
