Abstract: The denture construction teaching tool is an educational tool for instructing students on the molding process used to construct removable dental prosthodontics. The denture construction teaching tool includes a base having opposed upper and lower surfaces, and a spacer block releasably secured to the upper surface of the base. 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.

Abstract: The adjustable fixator for scanning dental casts includes upper and lower plates which are adapted for releasably securing a dental cast to be optically scanned therebetween. The upper and lower plates are selectively vertically adjustable with respect to one another, and a bottom surface of the lower plate is adapted for releasable mounting in an optical scanner. The upper plate is secured to a cylindrical shell which slidably receives a vertical support mounted to the lower plate, allowing the user to slidably adjust the height of the upper plate with respect to the lower plate. An engaging member mounted to the cylindrical support slides within a vertically extending slot formed through the cylindrical shell. The vertical position of the upper plate may be locked by sliding the engaging member into a selected one of a plurality of horizontally extending slots also formed through the cylindrical shell.
