In the event that someone loses all of their teeth due to age or other factors, dentures can replace the missing  teeth and allow the person to function better in their daily lives.  Not only are dentures useful in chewing, a well designed set of dentures can make the face look less aged. 

In certain cases, the dentures may be more stable and retentive in the mouth when 2 or more implants are placed in the lower or the upper jaws.
