Breast implants in the United States come from two manufacturers: Mentor( owned by Johnson & Johnson)and Inamed Natrelle(owned by Allergan). Both charge approximately the same fee for their saline and also for their silicone implants. Patients pay approximately $1000 for a pair of saline implants and $2000 for a pair of silicone implants. Custom-made implants would be more expensive as would double-lumen implants (implants that have silicone and saline chambers within the same implant)
