About die stone
Die stone is the high-strength, low-expansion gypsum for dies, a die being the positive reproduction of the form of a prepared tooth. Type IV gypsum has high strength and low expansion, which makes it the preferred choice for dental casts and dies. It shows high accuracy compared with other gypsum types because of its small setting expansion.
Gypsum is the natural hydrated form of calcium sulfate. Dental plaster is the beta-form of calcium sulfate hemihydrate, and dental stone is the alpha-form, with physical properties superior to plaster. A cast is a life-size likeness formed from a material poured into an impression.
ISO 6873 classifies the gypsum products used in dentistry for impressions, moulds, casts, dies, model bases and mounting models, and sets their requirements.
How plaster, lab stone, die stone and mounting stone differ
- Plaster — The beta-form: more porous and weaker than stone.
- Lab Stone — The alpha-form: the general stone for models and bases.
- Die Stone — The high-strength, low-expansion stone for dies and working casts.
- Mounting Stone — Made for attaching the cast to the articulator, not for pouring it.
What to look at when choosing a gypsum
Type: the gypsum type follows the job. A review describes Type IV dental stone as the high-strength material for models intended for fixed and combined prostheses.
Setting expansion is the dimensional increase that occurs as dental stone and die stone harden. A strong cast with a smooth, hard surface is needed for wax to be sculpted on it without abrading the cast.
Setting time differs between products: in one study the mean initial setting time ran from under 11 minutes for a construction gypsum to almost 25 minutes for a dental gypsum.
Pack and colour: the shelf lists each gypsum by weight, by colour and, where the maker states it, by ISO type.
