A device which provides for the positioning, alignment, and holding of dowel pins utilized in the construction of positive molds of a patient's teeth with removeable dies for dental prosthetic and restoration devices, including inlays, crowns, fixed and removeable bridges and precision attachments. The device includes a supporting rack, arch-shaped (as a row of teeth) and constructed of magnetized material, which receives a plurality of magnetizable dowel pin holders which are moveably positionable but firmly retained against the supporting rack. In one embodiment, the dowel pin holders are T-shaped and include a vertically adjustable tensioning means. The dowel pin holders when coupled to the supporting rack are positionable horizontally and vertically above a mold or impression which is received on a separate tray. The device allows for the positioning and holding of dowel pins in a manually arranged, three dimensional array, alleviating the use of complicated and complex connectors as found in the prior art.
