Using plaster expansion intelligently
no relief cuts necessary
➤ The expansion takes place through the full-model shape in three dimensions and evenly.
➤ The contraction of the impression is compensated by the expansion of 0.08%.
➤ No dimensional distortions as with dental arch models.
➤ No relief cuts necessary.
➤ No separate plaster base: no secondary expansion.
➤ Saw-cut model and counter bite fit together perfectly (both are full models).
