There are many different types of breast-augmentation. But as mentioned before, I have narrowed them down to two main categories: surgical and non-surgical. Lets start off with surgical breast-augmentation shall we?
Surgical breast-augmentation, or more commonly known as breast implants, come in 3 different types; saline implants filled with sterile saline solution, silicone implants filled with viscous silicone gel, and alternative-composition implants, filled with miscellaneous fillers — soy oil, polypropylene string, et cetera — that are no longer manufactured.
These implants filled with saline solution (Or more commonly known as salt water) were first developed in 1964 in France. The goal of this different type of implant was to perform surgical breast-augmentation with smaller incisions. The way that these implants work is that the empty implants are inserted and then filled with the solution afterwards. Because the implants are inserted empty, the resulting surgical scar will be smaller than the scar produced by the incision used for pre-filled silicone gel implants. Although the silicone breast implant has more superior aesthetic properties, the saline implants, if placed correctly, will have results just as good as the silicone gel implant. The down-side of the saline implant is that it has a tendency to cause noticeable rippling and wrinkling.
Silicone gel implants
These implants are usually described in 5 generations, defined by their manufacturing techniques meant to improve its physical and aesthetic realism. The first generation of silicone gel implants, produced in the 1960s, were a tear drop shape filled with a thick, viscous silicone gel. To reduce rotation of the implant up against the chest wall a fastener-patch, of Dacron (Polyethylene terephthalate) was affixed to the back of the implant. The second generation of silicone breast implants, developed in the 1970s, were softer and more life like, the manufacturers redesigned these ones with thinner shells and a thinner silicone-gel filler, but because of these new revisions there was more chance of the implant rupturing and filler leakage. These faulty silicone-gel implants were the subject of the lawsuits against the Dow Corning Corporation. This generation introduced some technological improvements though. The polyurethane foam coating, which reduced incidences of capsular contracture. And the development of the double lumen design, a silicone implant within a saline implant.
The third and forth generations, during the mid-1980s, introduced the elastomer-coated device shells, increased-cohesion gel filler. The elastomer-coated device shells and increased-cohesion (thicker) gel filler reduced the chance of filler leakage. Also introduced were anatomic (natural) and shaped (round, contoured) design varieties, available with either a smooth or a textured surface to control the movement of the emplaced implant device. The fifth generation, in the 1990s, introduced implants with a semi-solid gel that mostly eliminates filler leakage, this generation has reported low rates of capsular contracture and of device-shell rupture.
Polypropylene breast implants
Also known as string breast implants, are a type of implant, developed by Dr. Gerald W. Johnson. This device has been banned in the US and Europe. The polypropylene, which is yarn-like, causes irritation to the implant pocket which causes the production of serum which fills the implant pocket on a continual basis. This causes the breast to continuously expand after surgery. Problems can arise if breasts grow at different rates. This can be corrected by removal of serum with a syringe or introduction of sterile saline. String implants were only available for a very short time before being removed from the market by the FDA around 2001.
There aren’t many mainstream non-surgical breast augmentation procedures. There is the Thailand Breast Slap, which, outside of Thailand, isn’t used very much. There is the BRAVA breast enhancement and shaping system. There is also techniques using injections as well as through oral medications.
