U.S. government health regulators have ended a virtual ban on the use of silicone-gel breast implants.
The implants have been off the market since 1992 because of concerns about their safety.
On Friday, the Food and Drug Administration approved silicone-gel implants that two U.S. companies, Allergan Inc., and Mentor Corp., produce.
The F.D.A. withdrew its approval for silicone implants because of suspicions they were connected to a variety of diseases and complications. But in the years since, studies have found little evidence connecting silicone implants with disease.
Proponents say the silicone-gel implants look and feel more natural than implants containing salt water. There are no restrictions on those implants.
Impants are used for breast reconstruction or augmentation.
