Breast Implants like ALL implants (heart valves. pacemakers, hip joints etc) may become infected because they lack the blood vessels and blood flow which can fight infection. Infections can happen just after surgery or months to years later at which time it may be an infection elsewhere in the body which SEEDS the implants.
If a trial of IV antibiotics does not cure the infection and its symptoms the affected implants are removed along with the smooth scar envelope (capsule) around them. Cultures of the pocket are obtained. Massive irrigation of the pocket(s) is carried out before closing.
I would be in NO hurry to place an implant back there. Besides wanting to allow your body to remove all the bacteria that may still be in the pocket(s) after the surgery, we like to have breast tissues which are soft, free of inflammation which behave normally and cover the implant(s) normally. It takes 4-6 months for the body to reach that state.
You really should discuss this with your Plastic surgeon and see how he / she feels.
