Abstract

L'invention porte sur un protecteur de dent par lequel les dents peuvent être protégées de façon sûre d'un endommagement dans des lieux médicaux, des événements sportifs, etc. Un protecteur de dent comporte une partie revêtement de dentition maxillaire (10) recouvrant les dents individuelles de la partie gingivale externe à la partie gingivale interne des dents et s'étendant le long de la dentition maxillaire, une partie revêtement de dentition mandibulaire (11) recouvrant les dents individuelles de la partie gingivale externe à la partie gingivale interne des dents et s'étendant le long de la dentition mandibulaire, et une partie connexion (3) reliant la partie revêtement de dentition maxillaire (10) et la partie revêtement de dentition mandibulaire (11). Dans l'état habituel, la partie revêtement de dentition maxillaire (10), la partie revêtement de dentition mandibulaire (11) et la partie connexion (8) se présentent en une structure sous forme de plaque. Lors de l'utilisation, la partie connexion (8) est pliée puis le protecteur est monté. Ainsi, les dents individuelles dans la dentition maxillaire sont revêtues par la partie revêtement de dentition maxillaire (10) tandis que les dents individuelles dans la définition mandibulaire sont revêtues par la partie revêtement de dentition mandibulaire (11), empêchant ainsi de façon sûre que les dents ne soient endommagées.
