These crowns are cemented or screwed onto individual implants where a tooth has been lost.
These are bridges that are supported only by implants where there are no teeth, replacing anything from 2 teeth to the entire arch of teeth (so long as you use enough implants to carry the load!).
Implant Retained Dentures
The term “removeable” implies a denture which is anchored rigidly onto 2 or more implants, to stop it shifting or slipping in your mouth. 2 or more implants are used to secure the denture by means of friction studs or a metal bar. Apart from the greatly increased security of the denture retained by implants, there is also the added advantage (in the upper jaw) that the part of the denture covering the roof of the mouth can be left out giving the wearer much improved enjoyment of food and better speech.
The term “fixed” implies a tooth or teeth anchored rigidly onto an implant or implants. A fixed tooth crown is screwed into the implant, in the same way as a natural tooth crown is attached to the root of a natural tooth. Where 2 or more teeth side by side are missing, the replacement teeth are linked together to form a ‘bridge’ which is also screwed into 2 or more implants.
