Plaster | Gypsum | Dental Die Stones Products
Dental die stones are gypsum products used for making accurate dental models. These high precision stones are formulated for fabrication of crowns, bridges, implants, and orthodontic appliances in the dental lab and office. Our dental die stones include low strength model stone, resin-reinforced high-strength stones, and zero-expansion articulator super-high strength stones for accurate, stable models and dies.

Applications
Type 2 Dental Plaster (Model Stone):
- Diagnostic Models: Great for initial study casts for orthodontics and treatment planning.
- Articulator Mounting: Securely holds models on articulators for crown & bridge work.
- Flasking Support: Creates a base for models during denture processing.
- Supporting Structures: Provides temporary holding for casts during other procedures.
- Non-Functional Repairs (Limited): Can be used for temporary fixes (but not ideal for long-term).
Type 3 ZERO-expansion articulator die stone, high strength
- Purpose: Mounting master casts with maximum accuracy
- Applications:
- Articulating final casts and master casts
- Mounting implant and orthodontic casts
- Precision long-span bridgework
- Minimizing errors between articulated casts
Type 4 Resin-reinforced super high-strength hard die stone
- Purpose: High precision working models and accurate dies
- Applications:
- Fabricating crowns, bridges, inlays, onlays
- Producing orthodontic appliances
- Creating implant surgical guides
- Modeling complex restoration
