Phosphate-bonded, graphite-free, thermally resilient, precision investment material for the complete spectrum of the crown and bridge technique. Investment for stepwise preheating.
As a result of the fine-grain composition, very smooth and precise castings are achieved. Feguravest® ultrafine investment is the reliable alternative to obtain high-quality dental casts. Feguravest® ultrafine is mixed with a special liquid - Feguravest® Liquid - and can be diluted with demineralized water in any ratio. Thus the total expansion of Feguravest® ultrafine can be precisely adapted to the alloy used.
