Individual refractory dies are easily duplicated if teeth are to be remade, when there are margin chips, or bubbles are present. There is no need to start over and make a new base.

Having no pins in the refractory material itself has numerous advantages. There are no problems due to different coefficients of thermal expansion, contamination, pin placement or the fracturing commonly observed around pins.

Traditional model pin system techniques are utilized. There are no new techniques to learn and no additional equipment required.

Pins allow for greater accuracy since dies are not repositioned in original impressions as some techniques require.

No need to duplicate entire model means less expense for the technician.
