Doctors who have switched to automix delivery but prefer a higher-viscosity tray material can now get the best of both worlds. Imprint8™ 3 Pentah™ Putty Impression Material provides all the benefits of a true putty, including higher consistency and insertion force than heavy body materials. Plus, it is designed exclusively for use with the Pentamixr™ 2 Mixing Unit – enabling reliable and reproducible dosage.

Impression materials are generally used for securing a precise representation of oral hard and soft tissue to support and enable subsequent preparation of crowns, bridges, dentures and other oral prostheses. Several impression taking techniques like monophase shaping (one material at one time), sandwich technique (two materials at one time) and putty/wash technique (two materials subsequently at two different times) are known to the skilled person.

Generally, with this technique in a first step a putty material is used to obtain a supporting preimpression, which is subsequently in a second step refined by taking a second impression with a light body “wash” material. The kneadable putty material is cured as a preimpression material in the patients' mouth, trimmed after removing the preimpression from the mouth, and in a second subsequent step, is covered with a layer of a “wash” material and again cured in the patients' mouth in order to obtain a precise representation of oral hard and soft tissue. In the sandwich technique, this is done simultaneously during the pot life of the two materials, followed by simultaneously applying the two materials in the patients' mouth.

The preimpression material (putty) is often employed in the form of a kneadable putty material. When performing a process for taking an impression, the dentist usually relies on the preimpression material having a noticeable resistance upon contact between preimpression material and dental material with the advantage that a higher back pressure is generated in the impression tray when the impression is made. Such a resistance is desirable, since the danger of overpressing the material in the tray is limited. Since overpressing usually results in direct contact between the impression tray and one or more surfaces of dental material, information is lost and the impression may be useless.
