ABSTRACT:
An artificial tooth has a basal plane in which an areal ratio of a labial or buccal subplane to a lingual subplane is in a range of 10:1 to 1:10, and an angle that both subplanes make with a dental axis, i.e., an angle of retention, assumes a concave shape and is in a range equal to or larger than 45.degree. to less than 180.degree.. A retaining hole can be provided in the basal plane of the artificial tooth so as to further improve its performance.
