    摘要: A cap for an investment vessel for receiving investment material comprises a platform having a contoured edge and an underside. A wedge is located on the underside of the platform and is frictionally engageable with at least a portion of an inner edge of the top of the vessel. When the cap is placed in frictional engagement with the vessel, the contoured edge provides a restricted opening to the vessel for controlling the flow of the investment material. A lip is provided on the platform at the contoured edge for channeling investment material to the opening.

    摘要: An adjustable investment mold positioner includes a resilient band bent into a partial cylinder. Opposite ends of the band bound an opening at the side of the cylinder. A mold receiving member made of bent metal has side walls with bent connectors that are attached to the opposite ends of the band. A recess is formed between the side walls for receiving an oval investment mold. The outer cylindrical configuration of the positioner is readily engageable within the cradle of a conventional casting machine which is designed for normally receiving cylindrical investment molds. In this way, oval investment molds can be received in a secure manner within the conventional casting machines.

    摘要: Gate is a wax structure for forming part of a wax master in investment casting of a dental prosthesis. The gate has a square feeder with a circular disc on each end. The square feeder reduces the cracking stresses between adjacent feeders to reduce unwanted fins, and the square shape aids in final cutoff of the cast prosthetic. In the wax master, one of the discs is secured to the prosthetic form and the other disc to the conventional reservoir bar. The disc shape aids in filleting to the form and bar.

    摘要: 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. The faces are laser welded together, being dimensioned to a width that is between one and two times the effective welding depth of the focused laser beam so that the faces can be welded together across their entire areas from two opposite edges of the faces.

    摘要: An apparatus for gripping hot investment molds either of the ring type or of the oval type, has a plastic handle with an elongated square tube extending therefrom. A trigger in the handle is connected to a linkage rod which pulls back on a closer frame. Rearwardly extending crossed tails of a pair of jaws are squeezed together by rearward movement of the closer, for closing outwardly extending palms of the jaws around an investment mold. The jaw assembly is removable so that jaws having shapes adapted specifically to engage either an investment ring or an investment oval can be provided.
