If you are a dentist who regularly prescribes IPS e.max restorations, I strongly recommend that you purchase the IPS Natural Die Material Shade Guide from Ivoclar.
This guide will enable you to take the optimum shade after preparation. This will assist us in selecting the ideal ingot in which to press the restoration, thus ensuring that we are able to provide the best shade for your patient.
Should the preparation be darker than shade tab no. 9, or exhibit black areas, it is advisable for the dentist to correct this by using a light coloured composite or Ivoclar’s “Monopaque”.
