A set of tooth molds are releasably secured to the upper surface of the base about the spacer block. Each of the tooth molds has an injection port and a venting port formed therethrough. Each tooth mold further has a lower molding portion and an open upper portion. A removable lid releasably covers the open upper portions of the set of tooth molds, such that a molding material may be injected through the injection ports of the set of tooth molds with excess molding material exiting through the respective venting ports.
