Does Sientra warranty for ruptured implant still apply if I get Allergan? (Photo)

If my Sientra implants, implanted 8 years ago, have ruptured, will the warranty still apply if I get Allergan Natrelle implants during my revision? I understand they probably wouldn cover the replacement as it isn’t their brand, but what about a portion of the surgical costs? Anyone who has experience with this, I welcome your guidance! Thank you, Martha
