| Abstract: |
A device for supporting artificial teeth, which device is intended to be secured to anchoring elements in a jaw, includes tubes, which are secured to the anchoring elements, and a bridge formed as an integral piece and fixed to the end surfaces of the tubes. The end surface of each tube is in the same plane as the corresponding engagement surface on the bridge. For making the device, one or more planes are determined, giving the bridge 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 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.

We claim:
1. Device for supporting artificial teeth, comprising at least two non-bendable extension members and a tooth-supporting means extending therebetween, said extension members and said tooth-supporting means being an integral piece, each said extension member having a first end and a second end, said first end and said second end having end surfaces, said first end being securable to an anchoring element embedded in a jaw, said extension members forming extensions of said anchoring elements and having the same angles between their longitudinal axes as said anchoring elements, said tooth-supporting means extending between said extension members and being fixed to said second ends of said extension members, wherein at least one of said extension members has an end surface of its second end making an angle which is different from zero with the end surface of its first end, wherein said angle between the first and the second end surface is such that the second end surfaces of said extension members are located in and define parallel planes, and wherein said tooth-supporting means is fixed to said extension members prior to said use of the device in the jaw, said tooth-supporting means and said extension members being an integral piece, said tooth-supporting means having surfaces for engaging the extension members, said surfaces being located in said planes of their respective extension members.
