EXTRAVEST® is a graphite-free phosphate bonded investment specifically for use with the common types of dental alloys. It can be used with both rapid and programmed preheating, and also with the free expansion technique (ringless system). Expansion is controlled by means of the UNISOL® liquid, diluted with distilled water depending on the type of alloy used. Among its many advantages, EXTRAVEST® ensures easy model removal, while its fine grain guarantees precise castings with smooth surfaces. FIELDS OF USE: production of castings of bridges, crowns, inlays, onlays, telescopic crowns, trimming, counterparts, etc.
