のためにシエルを貼着したものが知られている。
この種の義歯は、前装材を象牙色と同様の黄色っ
ぽい白色とし、またシエルをエナメル質と同様の
半透明とすることにより、実際の歯と同様の色あ
いや質感を出すようになつている。(Prior Art) As a denture that is attached to a tooth whose surface has been removed due to tooth decay, it is known that a shell is attached to the surface of a veneer material to ensure aesthetics.
This type of denture has a yellowish white veneer similar to ivory, and a translucent shell similar to enamel, giving it the same color and texture as real teeth. There is.
（考案が解決しようとする課題）
シエルは、前装材が未硬化の状態で、その表面

上記色あいや質感が低下する問題があつた。(Problem to be solved by the invention) The shell is attached to the surface of the veneer material in an uncured state, but at that time, the shell is strongly pressed to ensure that it adheres to the veneer material. For this reason, conventionally, due to this pressure force, the veneer material unnecessarily protrudes and its thickness becomes thinner than the specified thickness.
There was a problem that the color tone and texture described above deteriorated.
そこで本考案は、このような問題を解決する義
歯を提供することを目的とする。 Therefore, the present invention aims to provide a denture that solves these problems.

を、実際の歯に酷似させている。 A plurality of rib-shaped spacing members 5 are provided on the inner surface of the shell 4 in a protruding manner. This spacing material 5 defines the thickness of the front cover material 3, and details thereof will be described later. Further, a recess 6 is formed in the lower part of the inner surface of the shell 4, and an ivory-colored filling 7 is mounted in the recess 6. As shown in FIG. 2, the ivory-colored filling 7 can be seen through the translucent shell 7, making the color and texture of the denture 1 closely resemble those of real teeth.

できる。 This denture 1 is made by coating the surface of a veneer 2 with an uncured veneer 3, and pasting a shell 4 on the surface to ensure aesthetics. In this case, in order to reliably attach the shell 4 to the front upholstery 3, the shell 4 tends to be strongly pressed onto the front upholstery 3, and in the conventional method described above, due to this pressure, the front upholstery A part 3a of the front cover 3 protrudes to the side (see the chain line in FIG. 1), which causes the problem that the front covering 3 becomes thinner than a predetermined thickness. However, since this product is provided with a spacing material 5, by pressing the shell 4 against the front covering material 3 until the spacing material 5 touches the interior material 2, the front covering material 3 can be made to a predetermined thickness, and the actual It can produce the same color and texture as your teeth.
