The affect (if any) is negligable. Silicone (like fat) resists electrical currents while saline (like lean muscle)is a conducter. However, neither one will make much difference. The current which passes between ankle and wrist electrodes usually side lines the breast area. There are measurement devices which require you to stand on a scale which also measures hydration and calculates body fat. The current on these meets in the waist area and also miss the breasts. Even if a measurement system were to use current which passes through the breasts, implants would not have much affect. The volume of implants in comparison to the total body volume is small.
