This refers to the materials that comprise the implants, and their are two main options, Saline or Silicone.
Since 70 percent of the human body is composed of physiologic saline (0.9% sodium in water), saline is a natural and ideal choice to fill a breast implant. This is an obvious advantage for a saline breast implant. Since saline implants are filled after they are injected, saline implants also require a smaller incision than silicone breast implants, which is important to many patients.
Today’s silicone gel implants are comprised of technologically advanced “memory gel” that more realistically mimics the natural consistency of breast tissue. Silicone gel implants will also provide a shapelier look.
Their are two breast implant shape options, either round or teardrop.
Teardrop breast implants are thinner on the top and gently slope to a fuller bottom, giving it that teardrop look. This design may sound like the best choice, but unfortunately we have found them to have serious design flaws. The implant has a potential of flipping upside down on itself or changing polarity during movement, which then requires surgical correction. This is an unnecessary risk in our experience.
Round implants, when in upright position, take a teardrop shape in the body anyway without the risk of flipping upside down. Thus, in the opinion of our medical staff that it’s futile to use a teardrop implant, making round breast implants the most popular and logical choice.
