A removable analog includes an analog pin having a tapered end and a location boss on the other end. A threaded tap is formed in the other end thereof. At least one flat surface is formed on a length of the analog pin to prevent rotation. At least one groove may also be formed on a length of the analog pin to prevent rotation. A second embodiment of the removable analog includes the analog pin and a sleeve. The sleeve has an internal contour which is sized to slidably receive the analog pin. One end of the sleeve has a tapered end and the other end is sized to receive the analog pin. At least one projection is formed on an exterior surface of the sleeve to prevent removal from a dental model.
