Abstract

Le groupe d'inventions se rapporte au domaine de la médecine, notamment de la stomatologie orthopédique, et peut être utilisé lors de la pose de prothèses. Le procédé est réalisé par étapes. La première étape consiste à effectuer une préparation thérapeutique des dents recevant une prothèse. La deuxième étape consiste à préparer les canaux radiculaires sous le pivot dentaire métallique. La troisième étape consiste à préparer le pivot dentaire avec un tube comportant un alésage interne et passant par le centre du pivot sur un plan vertical. La quatrième étape consiste à fixer les pivots. La cinquième étape consiste à préparer les dents, enlever les empreintes et préparer et fixer les couronnes provisoires. La sixième étape consiste à préparer un porte-empreinte individuel avec des ouvertures dans la projection des ouvertures filetées. La septième étape consiste à retirer l'empreinte à deux couche avec le porte-empreinte. La huitième étape consiste à fabriquer une carcasse de la prothèse de bridge en formant des ouvertures dans la projection des ouvertures filetées des inserts fixés dans les dents, et polir la carcasse avec une masse céramique. La neuvième étape consiste à fixer la prothèse de bridge finale aux dents sur un ciment, et à la fixer par des vis aux inserts. Afin de réaliser ce procédé, on utilise un nécessaire. Ce groupe d'inventions permet de prolonger la durée de vie de la prothèse de type bridge et des dents de support, sans recourir au sciage de la structure et à son recyclage de problèmes avec les dents de support ou des éléments de la prothèse.
