[0002] Dentures, commonly known as "false teeth", are a general term in medicine for restorations made after partial or complete tooth loss in the upper and lower jaws. They fulfill "duties" for humans, just like artificial legs and limbs. Dentures are usually divided into three types: removable dentures, fixed dentures, and implant dentures.
