Abstract: An artificial tooth for use in a denture comprising a base portion, an occlusal portion, and an intermediate portion sandwiched between and secured to the base portion and occlusal portion, the intermediate portion being resilient to permit the occlusal portion yieldably to move relative to the base portion. The intermediate portion is disposed generally at equal vertical distances from the occlusal surface of the occlusal portion and the ridge lap surface of the base portion. Two connecting members, spaced apart in the mesial-distal direction, are provided for limiting the movement of the occlusal portion relative to the base position. Such members are rigidly connected to the occlusal portion and loosely pivotally connected to the base portion. The loose pivotal connection permits the occlusal portion to move from its normal portion toward the base portion even by tipping movement.

Abstract: An artificial tooth for use in a denture comprising a base portion, an occlusal portion, and an intermediate portion sandwiched between and secured to the base portion and occlusal portion, the intermediate portion being resilient to permit the occlusal portion yieldably to move relative to the base portion. The intermediate portion is disposed generally at equal vertical distances from the occlusal surface of the occlusal portion and the ridge lap surface of the base portion. An anchor wire or wires or other connecting members are provided for limiting the movement of the occlusal portion relative to the base portion. Such an anchor wire may preferably be rigidly connected to the occlusal portion and loosely pivotally connected to the base portion with the anchor wire extending downwardly through the sandwiched intermediate portion. The loose pivotal connection permits the occlusal portion to move from its normal position toward the base portion even by tipping movement.

Abstract: Artificial teeth for use in a denture comprising a denture base and a plurality of teeth anchored in the denture base, each tooth having a base portion providing a ridge lap surface and an occlusal portion providing an occlusal surface, wherein the improvement comprises one or more lugs extending outwardly from each tooth intermediate its occlusal surface and the ridge lap surface to serve as a locating lug or tab for positioning the tooth in the mold in which the denture base is formed on the base portions of the teeth. These locating lugs or tabs or at least those which are not embedded in the denture base are removed by grinding and polishing.
