Abstract
(EN)
Provided are a cast tooth, cast tooth base and dental cast, using which a gap between adjacent cast teeth is unlikely to form. A cast tooth 20 to be used in a dental cast which is equipped with a cast tooth base 10 provided with a plurality of insertion holes 13 and insertion hole-side step sections 13b located on the inner surfaces of the insertion holes 13 and provided in a manner such that the far side of the insertion holes 13 is narrower than the insertion side thereof, and is further equipped with a plurality of cast teeth 20, each of which can be inserted into and removed from the insertion holes 13 and has a tooth crown section 21 which is exposed from the insertion hole 13 when inserted into an insertion hole 13 and a tooth root section 22 which is inserted into the interior of an insertion hole 13, the cast tooth 20 being configured in a manner such that the outside surface of the tooth root section 22 is further provided with a cast tooth-side step section 26 which contacts the insertion hole-side step section 13b when inserted into an insertion hole 13 and moves the cast tooth 20 in a direction which causes the distance between adjacent cast teeth 20 to decrease as the cast tooth 20 is inserted deeper into the insertion hole 13.

L'invention concerne une dent coulée, une base de dent coulée et un moulage dentaire, grâce auxquels un interstice entre des dents coulées adjacentes est peu susceptible de se former. Une dent coulée (20), à utiliser dans un moulage dentaire, est équipée d'une base de dent coulée (10) dotée d'une pluralité de trous d'insertion (13) et de sections étagées côté trou d'insertion (13b) situées sur les surfaces internes des trous d'insertion (13) et disposées de sorte que l’autre côté des trous d'insertion (13) soit plus étroit que leur côté d'insertion, et est en outre équipée d'une pluralité de dents coulées (20), chacune d'entre elles pouvant être insérée dans les trous d'insertion (13) et en être retirée et ayant une section couronne dentaire (21) qui est apparente depuis le trou d'insertion (13) lorsqu'elle est insérée dans un trou d'insertion (13) et une section racine dentaire (22) qui est insérée à l’intérieur d’un trou d'insertion (13), la dent coulée (20) étant conçue de sorte que la surface extérieure de la section racine dentaire (22) soit en outre dotée d'une section étagée côté dent coulée (26) qui entre en contact avec la section étagée côté trou d'insertion (13b) lorsqu'elle est insérée dans un trou d'insertion (13) et déplace la dent coulée (20) dans une direction qui amène la distance entre les dents coulées (20) adjacentes à diminuer lorsque la dent coulée (20) est insérée plus profondément dans le trou d'insertion (13).

隣接する模型歯同士の間に隙間が生じにくい模型歯、模型歯台、及び歯科模型を提供する。 本発明の模型歯20は、複数の挿入孔13が設けられ、挿入孔13の内側面に、挿入孔13の奥側が入口側より狭くなるように挿入孔側段部13bが設けられている模型歯台10と、挿入孔13のそれぞれに着脱可能で、挿入孔13に挿入されたときに挿入孔13から露出する歯冠部21及び挿入孔13の内部に挿入される歯根部22を有する複数の模型歯20と、を備える歯科模型に用いられる模型歯20であって、挿入孔13に挿入されたときに挿入孔側段部13bと当接し、模型歯20が挿入孔13内へ深く挿入されるにつれて、互いに隣接する模型歯20間の距離が縮まる方向に模型歯20を移動させる模型歯側段部26が、歯根部22の外側面に設けられている。
