Both silicone and saline breast implants are wonderful devices that each has been used successfully for many years. There is really not one that is the best choice for every situation. There are some things that the two types have in common and some differences as well.
Safety
When it comes to safety, the outer shell of each type is made out of silicone rubber. In one type the filling is sterile salt water and in the other type it is filled with a silicone gel. There does not appear to be a correlation between breast implants and lupus, breast cancer, autoimmune diseases or thyroid diseases. Both types of implants appear to be similar in safety issues.
Outer shells of the implants do not last forever. Both types tend to have a lifespan of about ten to twelve years. Some may last from fifteen to twenty years and others may only last about five years. Chances are that you are going to have to have your breast implants replaced at some point in time, but there is no set clock for when this may occur.
Choosing the Right Implant
Silicone implants are already filled and a bigger incision is needed to insert them. A saline implant can be adjusted, which is a benefit for the surgeon that is placing them.
Overall, the best implant for your situation is something that will need to be discussed with your doctor. There are pros and cons of each type, with the silicone implant being the more expensive choice. Both types of implants are relatively safe. When it comes down to it, choosing the type of implant is a personal choice that you and your doctor should agree on before having the procedure.
