Which type of gypsum is best used for orthodontic models?

Question

Quizplus · Accepted Answer

Dental stone is the best choice for orthodontic models as it has high compressive strength, low setting expansion, and can be easily worked with. Impression plaster and model plaster are not suitable for orthodontic models due to their weaker strength and higher setting expansion, respectively. Improved stone is often used for creating high-precision restorations and may not be necessary for orthodontic models.
