Reusing an implant is against the manufacture guidelines. A malpostioned implant should first be removed, the wound must heal and 3 to 4 months later a new implant should be placed in a proper pocket.
In the US it is recommended that breast implants are one time use. Taking the implant out, and repairing the pocket, while the implant is in an antibiotics bath, and reinserting back. There is the risk that the shell of the implant will be weakened by removing and reinserting. Plus the risk of contamination.
