A device for supporting artificial teeth, which is intended to be secured to anchoring elements (1, 4) in a jaw (14), comprises tubes (19) which are secured to the anchoring elements, and a bridge (25) formed as an integral piece and fixed to the end surfaces of the tubes (19). The end surface of each tube (19) is in the same plane (30) as the corresponding engagement surface on the bridge. For making the device, one or more planes (30) are determined, giving the bridge (25) a suitable position in relation to the anchoring elements, and the tubes are cut such that their end surfaces will be located in the planes (30) when the device has been secured to the anchoring elements. Each of the engagement surfaces of the bridge is thereafter processed so as to be located in the same plane as the end surface of the corresponding tube, and the bridge is finally secured to the tubes by welding.
L'invention porte sur un dispositif de support de dents artificielles, qui doit être fixé aux éléments d'ancrage (1, 4) dans une mâchoire (14). Le dispositif comprend des tubes (19), fixés aux éléments d'ancrage, et un pont (25) formé comme partie intégrale et monté sur les surfaces d'extrémité des tubes (19). La surface d'extrémité de chaque tube (19) arrive sur le même plan (30) que les surfaces d'appui correspondantes du pont. Pour la fabrication du dispositif, il faut déterminer au moins un plan (30) afin de donner au pont (25) une position appropriée par rapport aux éléments d'ancrage. En outre, les tubes sont coupés de manière que leurs surfaces d'extrémité se situeront sur les plans (30) lorsque le dispositif aura été fixé aux éléments d'ancrage. Chaque surface d'appui du pont est ensuite traitée pour se retrouver sur le même plan que la surface d'extrémité du tube correspondant, puis le pont est finalement soudé solidement aux tubes.
