There are two primary types of implants; silicone-based and saline-based. Both have their own unique pros and cons. Saline implants result in significantly less scarring because they are filled after insertion. This means they require a much smaller incision. They are, however, more prone to rippling and don’t feel or look as natural. While silicone implants are less prone to ripple or deform, and look and feel more natural than saline, they require a much larger incision which means a much larger scar.
The implants are placed either underneath the breast tissue or, if there isn’t enough breast tissue, underneath the chest muscles. In some cases, implants are also used as part of a breast lifting procedure, in particular for women who have lost significant breast mass after breast-feeding or losing a great deal of weight. The entire implanting procedure generally takes between one and two hours, and involves the use of general anesthetic.
