ABSTRACT:
A magnetic pin setter useful in constructing replicas of teeth for production of crowns and bridges. The device employs two support rods mounted on a base, each supporting a horizontal plate at its upper extremity. Mounted on the base between the two support rods is an adjustable work table. In producing castings for restoration work including crowns and bridges, dowel pins must be positioned for the casting and removal of individual tooth models to be restored. Small horseshoe magnets are magnetically attached to the horizontal plates and the second magnet interconnected to the first magnet holds a vertical support rod in position. The rods retain the dowel pins in position in the center of the individual teeth for the casting process.
