Abstract: Assembly for supporting a submaxillary denture on a lower jaw, comprising a base plate, which has the form of a curved strip, a bridge member on which the submaxillary denture is to be placed, a set of columns which are provided with threaded bores in which fixing screws fit to connect the columns with the base plate, and which are connected with the bridge member in order to allow the base plate to support this bridge member, a set of cortical screws for securing the base plate to the lower jawbone, the base plate being provided with first holes for receiving the fixing screws for fixing the columns to the base plate and second holes for receiving the cortical screws, the first holes being formed as elongated holes, the main axis thereof extending substantially transversely to the principal direction of extension of the strip-formed base plate and the longitudinal boundaries of the elongated holes being curved convexly in a plane parallel to the longitudinal plane of symmetry of the elongated holes, and the

Abstract: A system providing support on the lower jaw for a submaxillary denture wherein a base plate comprising an arcuate metal strip having an intermediate portion, the centerline of which in plan view being an arc across a subtending chord 34 mm in length and with a height of 8 or 10 mm;a bridging means comprising hooking means for coupling means included in a submaxillary denture;a set of posts to stand on said intermediate portion for carrying said bridging means;a fixing means for each of said posts to fix said bridging means; and a set of cortical screws to adjoin said base plate fixedly to the lower face of the lower jaw at locations on either side of each of said posts.Each of its parts is made up of gold 18-5 (gold of 18 carat, allowed with 5% platinum).
