Mentor or McGhan Saline Breast Implant Replacement or Warranty Policy?

It is very odd to have an implant erode 10 years after implantation without some type of trauma or systemic infection. As stated in previous posts, the manufacturers' warranty just covers deflation of the implant. Since this is not really an implant problem I doubt you would have coverage.
You should wait for several, maybe 6 months before replacing your implant to be sure the infection is cleared up. You probably lost some tissue during this process and there is the possibility that your breast won't match even after replacing the implant.
Good Luck!

Your predicament sounds very unfortunate and is indeed very rare. In any case, it is not a situation that would be covered by the implant manufacturer, since those policies are for deflation of the implant. I hope things work out well for you.
