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.
