Abstract
The denture has the root of an artificial tooth embedded in a denture base molded from plastic. The artificial tooth is provided with a through-hole in the root that fills with denture base plastic, and the openings at both ends of the through-hole are embedded in the denture base. Further, both ends of the through-hole open at artificial tooth surfaces that face adjacent teeth, and an air-vent is provided that connects with the through-hole. The opening for the air-vent is positioned on a lingual side surface of the artificial tooth that is exposed from the denture base. Plastic that forms the denture base flows into the through-hole and air-vent embedding and retaining the root of the artificial tooth in the denture base.

A denture comprising:
- a denture base formed from plastic;
- and
- an artificial tooth with a root that embeds in the denture base,
- wherein the artificial tooth is provided with a through-hole in the root that fills with denture base plastic, and openings at both ends of the through-hole are embedded in the denture base,
- wherein both ends of the through-hole established in the artificial tooth open on surfaces that face adjacent teeth;
- an air-vent is provided that connects with the through-hole inside the artificial tooth,
- wherein the opening for the air-vent is positioned on a lingual side surface of the artificial tooth that is exposed from the denture base, and
- wherein denture base plastic flows into the through-hole and air-vent and embeds the root of the artificial tooth in the denture base.
An artificial tooth with its root embedded in a plastic denture base, having a through-hole that fills with denture base plastic established in the root,
- wherein denture base plastic flows into the through-hole and attaches and embeds the artificial tooth in the denture base,
- wherein the through-hole established in the root opens at both ends on surfaces that face adjacent teeth;
- an air-vent is provided that connects with the through-hole inside the artificial tooth,
- wherein the opening for the air-vent is positioned on a lingual side surface of the artificial tooth that is exposed from the denture base, and
- wherein denture base plastic flows into the through-hole and air-vent and embeds the root of the artificial tooth in the denture base.
A method of attaching an artificial tooth to a denture base comprising:
- establishing a through-hole in the root of the artificial tooth that is designed to be filled with denture base plastic, and has openings at both ends in surfaces that face adjacent teeth;
- establishing an air-vent that connects with the through-hole inside the artificial tooth, and has an opening positioned on a lingual side surface of the artificial tooth that is exposed from the denture base;
- and
- flowing denture base plastic into the through-hole and air-vent and embed and attach the root of the artificial tooth in the denture base.
