A Dallas plastic surgeon that performs breast augmentations will be able to explain the differences and benefits of saline and silicone implants. If you want breast implants, deciding on an implant type is something that you will need to do.
Silicone implants are a bit firmer than saline implants. They are said to feel more like a real breast and have a fuller rounder appearance. They are less likely to rupture and rippling is less likely as well. Rippling is when you can see wrinkle type lines on the breast which are created by the implant.
Saline implants are safe for the body and are usually the preference of a Dallas plastic surgeon. Saline is safer for the body should it ever rupture. Saline is also easier to insert into the breast area during surgery. The cons of saline implants are that they run a higher risk of rippling and rupturing. Although, both of these issues with saline implants are continuously being improved.
Ultimately, the choice of implant is yours. It will also depend on your body and breast area. Your Dallas plastic surgeon will help guide you in your decision with their knowledge of breast implants and the surgical process.
