Abstract

L’invention concerne un dispositif d’hygiène dentaire, comportant un boîtier, un axe menant, un axe mené et une tête abrasive. La tête abrasive coiffe l’axe menant et s’y rattache de façon amovible. Le dispositif d’hygiène dentaire comporte également au moins un axe de transmission. L’axe menant comporte au moins une ouverture au niveau de sa surface d’extrémité proche de l’axe mené et l’axe mené comporte au moins une ouverture au niveau de sa surface d’extrémité proche de l’axe menant. Une extrémité de l’axe de transmission est partiellement insérée dans l’ouverture de l’axe menant et l’autre extrémité est partiellement insérée dans l’ouverture de l’axe mené. L’axe de transmission couple l’axe menant à l’axe mené, tous les axes étant logés dans le boîtier.
