An element intended for an orthodontic system comprises: a fixing surface to be attached to the wall of a tooth； a body, having sides counterposed with respect to the fixing surface and defining a groove passing through sides, for housing an arch wire that can be removed and protrudes while being kept in the groove through at least one of sides with respect of the element； a slit passing through the sides toward the groove in order to assemble the archwire in the groove. In this way the play between the arch wire and the hole is lower than the space between the archwire and the groove, in order to keep the archwire in the body.
