Developed specifically for orthodontic use, ORTHODONTIC PLASTER is harder and whiter than ordinary plaster. It has a long working time and trims easily. To provide an accurate and dense cast, finest results are obtained when mixed under vacuum. To produce a glossy surface, finished models may be treated with MODEL GLOW model soap.
