This assembly device comprises a capsule (1) containing a permanent magnet (12) housed in a casing (5) which is closed by a lid (13). The latter and the casing are made of a ferromagnetic material. The base (6) of the casing and the wall (8) of the latter are connected to one another via a thin peripheral panel (7) forming a saturable zone of high magnetic reluctance. The flux lines produced by the magnet (12) are thus concentrated at the base (8a) of the wall (8) of the casing (5). …<??>Application to the retention of dental prostheses. …<IMAGE>… |
