A one-piece U-shaped bar is arranged to support an artificial denture on its upper edge. The front of the bar is curved and the side portions thereof are substantially straight whereby to be of a contour similar to the contour of the lower jaw of a person. The bar has rear ramus implant portions as well as a front implant portion. Each of the ramus implant portions extends upwardly at an angle greater than a right angle but less than 180 DEG relative to the bar and also comprises an extention of the sides of the bar. Except for a small outward bend of the bar at the sides immediately forward of the ramus implant portions, the latter are substantially in longitudinal alignment with such sides. The ramus implant portions project upwardly as well as downwardly relative to the bar, with the upwardly extending portion having a length substantially greater than the downwardly extending portion. These upwardly and downwardly extending portions are pointed at their ends.
