den·tal stone

(dentăl stōn)
Alpha form of calcium sulfate semihydrate with physical properties superior to those of the beta form (dental plaster); consists of cleavage fragments and crystals in the form of rods and prisms and is thereby denser than the beta form; can form a dense stonelike material when mixed with water; used to pour models (casts) of dental structures.
