There are advantages and disadvantages to both.  With the prosthetic implant, advantages would include preformed shapes that are considered "ideal" in proportions and are very accurate, ease of obtaining (no donor surgery site), and multiple choices.

The primary advantage to using your own tissue (such as rib) is that it is living.  Compared to artificial materials, this means a much lower rate of infection and a much lower rate of extrusion (pushing out through the skin).  Artificial implants carry a risk of these things happening for the rest of your life.  Living tissues such as rib cartilage are very unlikely to have one of those problems, especially if it makes it past the first month or two.

Rib cartilage does require a second surgery site and possible complications at that site.  It also has a tendency to warp several months after surgery, and it can't be formed into nearly as perfect a shape as the machine made implants.

Neither choice is a clear winner, that is why you see it done both ways.  There is surgeon preference, as well as the specifics of the patient that might affect your choice. 

You should absolutely have your implant removed and not replaced!  Although silicone nasal implants are very popular and common in treating an Asian nose, many will extrude or become infected.
