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. Two such anchor wires prevent the occlusal portion from twisting relative to the base portion. The anchor wire or wires prevents the occlusal portion from moving from its normal position away from the base portion.
