Abstract
Coupled artificial teeth which minimize the shaping work of gum when manufacturing a denture model and eliminates residues in the plaster mold are disclosed. A coupled artificial tooth assembly includes a plurality of teeth coupled together only by wax. On the front side of the gum, the wax covers a base portion of each of the artificial teeth and fills the interdental papillae, while exposing the tooth crowns. On the backside of the gum, the wax fills the space around the bottom portion of each of the artificial teeth so that the bottom portion is almost completely exposed. The backside of the gum is substantially flush with the bottom portions of the artificial teeth and forms a bow-shaped curved surface similar in shape to a real human gum.
