Impression of the abutments is a significant procedure during the prosthodontic treatment, as it could directly affects the precision of the cast and the fit of the final restoration. The chemical and physical properties of elastomeric impressions materials may influence the accuracy of the final impressions.  Selection of the impression material should take in consider : the consistency and flow properties, ease of handling, the setting time and dimensional stability. The most used elastomeric impression materials for fixed and  removable prosthodontic restorations are polyvinylsiloxanes (PVS) and polyethers (PE). Polyvinylsiloxane impression materials provide simplicity, high dimensional stability and accuracy, superior elastic recovery from undercuts and low viscoelastic properties, low distortion, adequate tear strength varying with ?ller rate and viscosity, high ?ow characteristics, short setting time, and multiple pouring from one impression. Impression materials generally require compromises. They either exhibit good flow characteristics or stability.  The VPSbased precision impression material Honigum, however, is different. Thanks to the DMG-patented rheologically active matrix Honigum-Light, Honigum-Mono and  Honigum-Heavy yield best results in both disciplines.And the DMG Putty variants overcome the opposites at exactly the most critical point for the dentist and treatment. With its unique Snap-Set technology the hand-mix ......
