All-on-4 is a great replacement for the person who has already lost all of their teeth and is wearing a full denture but cannot stand it. OR a person who knows their remaining teeth are going to be lost and doesn’t want to ever have to wear a denture.
How does it work?
It is, at its simplest, a denture which is screwed to the jawbone by 4 implants.
It is fixed into position so that it doesn’t move at all, like your teeth
Why wouldn’t everybody just get All-on-4 instead of a denture?
They do require maintenance, like your natural teeth.
They don’t feel exactly like your real teeth, although other people could think they are your own.
It is probably the single most costly procedure in dentistry although it can still be great value for those who get it because it is transformative. Even at the price I have heard patients who have had it done say it was the best money they ever spent at the dentist.
Why should I even consider it, then?
They can transform the appearance of your smile because you can ask to have them set up with straight teeth (great when your natural teeth were never straight!) and you can pick whatever colour you want them to be (great when your natural teeth never looked white!). And the denture never comes loose, ever.
