There are two basic groups:
Fixed teeth – patient cannot remove the teeth
Removable teeth - Patient can remove the teeth.
If you are missing one or several teeth, but still have many of your own natural teeth remaining in the arch then fixed options are usually recommended.
Note how the adjacent natural teeth are not altered. Replacement teeth remain independent of the remaining natural teeth.
Wherever possible it is recommended to have one implant per replacement tooth in order to maintain the bone mass.
If you are currently wearing complete dentures, or will soon have all remaining teeth removed then there are many choices for you to consider.
