Abstract

La présente invention concerne un implant de dent individuelle intra-osseux pour une prothèse dentaire fixe avec une structure d'implant et un corps de base. Le diamètre extérieur de la nervure de guidage de la structure d'implant est inférieur au diamètre extérieur du corps de base dans la zone de son bord frontal crânien. Une surface de bord frontal coronaire sensiblement dégagée est formée entre une arête de bord frontale périphérique du corps de base et une arête de bord frontal interne de celui-ci. La surface d'appui d'épaulement du corps de base dans la cavité annulaire fait saillie vers l'intérieur de manière principalement radiale depuis la paroi interne de la cavité annulaire. La paroi externe du corps de base est rugueuse et/ou microstructurée et/ou nanostructurée au moins dans la zone du manchon de guidage jusqu'à l'arête de bord frontal périphérique du corps de base.
