CA 2672880

The present invention relates to a dental prosthesis, and more particularly, to a screw- engagement type dental prosthesis which enables non-preparation of the natural tooth because it is manufactured by division into two pieces or three pieces, which can be simply installed, and in which the occlusal pressure can be uniformly dispersed. Also, the present invention relates to a method of casting a screw- engagement type dental prosthesis by using a bolt made of carbon or ceramics. Furthermore, a keeper and a body are engaged with each other via a bolt in a state where thin and semi -conical maintaining portions formed on inner inclination surfaces of abutment teeth of both sides with a small preparation are accurately engaged with keys formed on inner inclination surfaces of the keeper and the body in correspondence to the maintaining portions.

La présente invention concerne une prothèse dentaire et notamment prothèse dentaire de type vissé qui permet d'éviter la préparation d'une dent naturelle grâce à son procédé de fabrication par la division en deux ou trois pièces qui peuvent être installées simplement et dans lesquelles la pression occlusale peut être dispersée uniformément dans la prothèse. L'invention concerne également un procédé de coulage d'une prothèse dentaire de type vissé au moyen d'un boulon réalisé en carbone ou en céramique. En outre, un crochet et un corps sont raccordés l'un à l'autre au moyen d'un boulon, les parties de maintien minces et semi-coniques formées sur les surfaces d'inclinaison internes de la dent d'appui des deux côtés, avec un préparation minimale, étant raccordées avec précision aux pattes formées sur les surfaces d'inclinaison internes du crochet et du corps, de manière à correspondre aux parties de maintien.
