By Sandra Downs Breast augmentations are a great way to get the breast size that you always wanted. Whether you wanted them bigger, smaller, or a different shape, plastic surgery is the procedure that will leave you with great results. One of the most popular types of breast augmentations is breast implants. Breast implants can be made from different materials. Saline implants are made from room temperature vulcanized shells made up of silicone elastomer and are filled with saline water once they are inserted in the body. This type of implant creates a smaller scar since the actual implant is empty during the procedure. Silicone gel implants are another common form of breast implants, and they can be split into five generations defined by their manufacturing techniques. First Generation: These implants were made of a silicone sac which contained a viscous silicone gel and a Dacron patch that reduced rotation of the implant. Second Generation: Second generation implants became more lifelike at the request of patients. In the 1970′s these implants caused problems because their thin shells sometimes ruptured. Third Generation & Fourth Generation: During the mid 1980’s the shells were coated with an elastomer which decreased leakage problems. This generation of implants also started changing shapes from the previous groups. The surface of the silicone implants was textured in order to reduce rotation. Fifth Generation: These implants are made from a semi-solid gel which makes it less likely for the silicone to move around. The fifth generation of silicone implants is solid and very cohesive which makes them have a more stable form and bring better results to the patients. Breast augmentation can be considered an art and the type of products the surgeons use are key to a successful procedure. The evolution of breast implants over time has made breast augmentation a common procedure.
