Type III universal dental stone.
Bisico® Synth-Dur is a synthetic Type III dental stone. As the colour of the gypsum is natural white, it can also be used safely for investment of heat-curing (Positioner or BISICO Lutemoll). Due to the specific properties of this kind of gypsum, it is particularly suitable for orthodontic applications. The expansion of 0.14 % is low and thus meets the requirements of dental work.
