Abstract: A method of investment casting a dental restoration and a dental restoration made, thereby and a pattern therefor, include, in the preferred embodiment thereof, the forming of a wax pattern that includes at least two wax retainers interconnected by a wax link that includes a separable link made of a preformed wax pair of blades with confronting parallel identically shaped surfaces in prepositioned intimate contact. The link is preferably set into a slot of the same thickness as the link cut into the connector of the pattern as the retainers are mounted on precisely positioned models of tooth abutments, and waxed to the connector faces exposed by the cut. The link is then separated to divide the pattern into two components from which corresponding sections of the restoration are cast by the lost wax investment casting method. The cast sections so formed have weldable faces thereon corresponding to the interface surfaces of the link blade of the pattern components.
