Multiple tooth replacement

It is not necessary to have one implant for each missing tooth. For example if three teeth are missing two implants can be placed and three teeth attached as a bridge.

Alternatives for several missing teeth

The alternative would often be removable partial denture. Many patients find they would prefer a fixed solution.

In some cases where there are teeth either side of the missing ones bridgework is an option. However the longer span of this would increase the chances of problems. 

Are the new teeth joined together?

When multiple implants are placed, they are routinely joined together in the same way that a bridge supported by natural teeth would be designed.

If enough implants are available, it is often easier and just as effective to make several smaller sections of bridgework each supporting a few teeth. The overall effect in the mouth is the same and if you ever need to repair one of the small sections, this can be very much easier to do.

Again the bone quality and the number and position of the implants will largely determine which option is most suitable for you. When implant-supported teeth are linked together, they are mechanically stronger than the individual parts and can better resist the forces of normal function which will try and undo the screw components, posts and/or cements that secure the underlying structure to each of the implants. For most implant-supported teeth you will be able to clean around each supporting implant by brushing and flossing in just the same way that you would around natural teeth and tooth-supported bridges. In some areas special floss, interdental toothbrushes and other cleaning aids may be needed to maintain good oral hygiene. Cleaning is not at all difficult, provided that you do not have impaired use of your hands.
