よる破断を予防している。The portions A, B, D and E of the spring wire 1 are hard (high Young's modulus) and the portion C is soft (low Young's modulus). The portion B is a region adjacent to the region A buried in the denture base 3 of the lower denture structure 7. The portion D is a region adjacent to the region E inserted into the insertion hole of the denture base 4 of the upper denture structure 8. Areas B and D are areas outside the denture base but are not preferable to bend. As described above, the fact that the hardness in the A, B, E, and D regions is higher than the hardness in the C region means that the spring wires 1 and 2 are bent into a U shape as shown in FIG. At the time of jaw movement, the end of the fixed area between the spring lines 1 and 2 and the denture bases 3 and 4 (spring lines 1 and 2)
Boundary of A, B area and boundary of E, D area in 2)
The stress is prevented from being concentrated on the spring wires, and the spring wires 1 and 2 are prevented from breaking due to metal fatigue.

The denture structure 7 is pressed against the lower gum and the upper denture structure 8 is pressed against the upper gum. Lower denture structure 7
Is pushed downward and the upper denture structure 8 is pushed upward due to the elasticity of the spring wires 1 and 2. So, not only when you move the lower jaw up and down, but also when you move the lower jaw left and right,
The pressing force hardly changes. Further, since the spring wires 1 and 2 have a length longer than the range in which the lower jaw can move, a stable pressing force is always applied to the lower denture structure 7 and the upper denture structure 8 regardless of the movement of the lower jaw.

ことはない。Therefore, in the denture structure of the embodiment shown in FIG. 1, the lower denture structure 7 is stably pressed against the gingiva of the lower jaw so that the denture does not come off from the gum during chewing or exercising food.
The upper denture structure 8 can be pressed against the upper gingiva.
Further, in this denture structure, mounting is easy because no attachment / detachment of the adhesive is required. Of course, there is no need to perform open surgery on the gingiva or modify the mandibular bone, so that the user is not burdened mentally and physically.
