Previously it was limited by number and placing of remaining teeth, because that we were not being able due to that to choose this as solution. However with dental implants we can achieve conditions for bridge placing. Because of that we can place it on two or more implants. Therefore it can be fixed by cementing and with screws. But big advantage of using screws is that gums stay healthy, in contrast with cementing gums can get inflamed. With screw fixation it is simple to for instance detach dental bridge if needed. Finally, most known dental implant bridge fixation is All on 4 technique.
Likewise, carriers for it can be natural teeth in combination with dental implants. When we use this technique we need to follow specific guidelines, like statics and bridge construction. Therefore, when we install one or two dental implants, we avoid dentures due to preserving natural teeth.
Above all main advantage is construction that is fixed with carriers what ensures proper transfer of chew power to the jaw bone so due to that patient gets natural feeling.
