Abstract: An apparatus for simultaneously separating segments of a dental cast from a plaster base wherein the segments are mounted to the base with pins positioned within holes that extend through the base with the apparatus comprising a platform and a clamp for positioning the base in a predetermined position spaced from the platform. A set of engaging pins are positionable upon the platform in alignment for insertion into the holes of the base. A threaded driver is provided for moving the platform and engaging pins thereon toward a base located at the predetermined position to engage the engaging pins with the dental cast pins thereby dislodging the pins and separating the segments from the base.
