Abstract

La présente invention concerne un porte-empreinte dentaire en forme de U comprenant une première partie de manche et une première partie d'accueil de matériau d'empreinte en forme de U, la première partie d'accueil de matériau d'empreinte en forme de U comprenant un premier support ayant un rayon de courbure plus grand que celui des dents, un second support ayant un rayon de courbure plus petit que celui des dents, un premier tissu filet placé entre le premier support et le deuxième support, et des premiers trous de re-décharge d'empreinte qui sont respectivement percés sur un côté des parties supérieure et inférieure de la surface incurvée du premier support ou de la surface incurvée du deuxième support autour du premier tissu filet, et une partie d'extension symétriquement étendue depuis le centre en U dans la première partie d'accueil de matériau d'empreinte en forme de U est étendue au-delà du point occlusal des dents. En outre, les premiers trous de re-décharge d'empreinte sont formés de manière telle que la section transversale du trou formé sur la surface externe du premier support ou du deuxième support est plus grande que celle du trou formé sur la surface interne du premier support ou du deuxième support, et une pluralité de premiers trous de re-décharge d'empreinte sont formés de manière telle que chaque trou peut être percé vers la partie supérieure du premier support ou du deuxième support et qu'un trou adjacent au trou peut être percé vers la partie inférieure du premier support ou du second support. En outre, la présente invention concerne le porte-empreinte dentaire en forme de U comprenant une deuxième partie de manche et une deuxième partie d'accueil de matériau d'empreinte en forme de U, la deuxième partie d'accueil de matériau d'empreinte en forme de U comprenant des troisièmes supports en forme de U étroits formés de façon à permettre à une rangée de dents de rentrer dedans, un deuxième tissu filet placé entre les troisièmes supports, et des deuxièmes trous de re-décharge d'empreinte qui sont respectivement percés sur un côté des parties supérieure et inférieure de la surface incurvée des troisièmes supports autour du deuxième tissu filet, et une partie d'extension symétriquement étendue depuis le centre en U dans la deuxième partie d'accueil de matériau d'empreinte en forme de U est étendue au-delà du point occlusal des dents. Les deuxièmes trous de re-décharge d'empreinte peuvent être formés de manière telle que la section transversale du trou formé sur la surface externe des troisièmes supports est plus grande que celle du trou formés sur la surface interne des troisièmes supports, et une pluralité de deuxièmes trous de re-décharge d'empreinte sont formés de manière telle que chaque trou peut être percé vers la partie supérieure des troisièmes supports et un trou adjacent au trou peut être percé vers la partie inférieure des troisièmes supports. Selon la présente invention, il est possible de réaliser économiquement une empreinte dentaire car l'empreinte dentaire peut être réalisée de façon stable sans utiliser de quantité excessive de matériau d'empreinte pendant un procédé de prise d'empreinte (procédé de durcissement de matériau d'empreinte). En outre, il est possible de réaliser facilement une empreinte dentaire car des trous coniques sont formé d'un côté des supports (le premier support, le deuxième support et les troisièmes supports) de la présente invention, en empêchant ainsi la séparation d'un matériau d'empreinte du porte-empreinte par un choc externe après durcissement.
