There are many types and shapes of dental prostheses.

Can be classified into two main groups:

1. Removable dentures
2. Fixed prosthodontics. Within these deserve a special section Implants.

Removable Prosthesis

Are those that can get in and out, ie not bound to oral structures, but simply anchored in them.

Are attached by adhesion to the gum, so that the tissue-call.

The other type of removable prosthesis is formed by those that support the teeth and, sometimes, also on the gums. Are mucodentosoportadas.

They are made with a metal frame that rests on the gum and hooks to anchor in the teeth.

They are less bulky than the tissue-and therefore something more comfortable, but they need to have a sufficient number of teeth and that they have acceptable conditions and are strong enough.

Must be all that common characteristics are described below:

1. Stability. Is the property of the prosthesis should not slide or swing in the mouth.
2. Retention. It is the anchor for the prosthesis should not detach. Achieved with hooks or clasps.
