This advanced review will discuss the history of implants used in breast reconstruction and augmentation, the most frequently performed plastic surgery today. Currently, only silicone rubber-based silica nanocomposite implants are available in the United States. The most prevalent issues involving breast implants include capsular contracture, gel bleed, implant rupture, and infection. In the past, studies have also been reported which linked breast implants to increased incidence of systemic diseases such as autoimmune disease, various forms of cancer, and psychological disease. The goal of this review is to survey the literature from the perspective of material science. It is also largely unnoticed that nanotechnology is involved: the silicone rubber shell is reinforced with nanosilica so implants appear to be homogeneous and crystal clear. We are hoping that this review will contribute to a better understanding of the controversial issues and motivate material scientists and medical doctors to work together to develop alternatives based on new nanotechnology for the women who opt for a device made of synthetic materials.
