Orthodontic stone is used to fabricate models for orthodontic cases. These stones are designed to pour up extremely smooth models, with the high durability required for orthodontic uses. Orthodontic stone is almost always white in color, allowing for optimal esthetics when the models are used to design orthodontic appliances. Orthodontic stone requires a precise mix in order to produce solid models without voids or bubbles.
