Abstract:
An artificial anterior tooth capable of grinding food is provided. The lingual side of an artificial anterior tooth is provided with a protuberance for forming a frictional surface dented in an arch shape as seen from the mesiodistal direction, and the labial side of an opposite artificial lower tooth is provided with a protuberance for forming a sliding surface abutting the frictional surface and sliding on the frictional surface by a sliding motion of the upper and lower jaws.
