Fig. 01 The thixotropic nature of Impregum polyether impression material ensures it stays in place after syringing

Fig. 02 This full arch impression with preps on Nos. 21-28 shows excellent capture of all margins and soft tissue, without material running down the throat

Fig. 03 Again, the thixotropic qualities of the material ensure it stays in place even on the upper arch

Fig. 04 An impression for a 3-unit bridge shows excellent detail capture with no voids or tears

Fig. 05 This polyvinyl impression shows a poor bond between the two materials, runny wash material and a pull on the impression, which is typical with many VPS impressions
