Technical Advantages
The advanced formula of Dental Stone Type Ⅲ incorporates proprietary additives to optimize setting kinetics and mechanical properties. Its low expansion rate (0.15-0.3%) minimizes distortion, ensuring models remain true to the original impression. The fine particle composition allows for seamless integration with impression materials, capturing even the most intricate sulcus details and occlusal surfaces. Additionally, the stone’s high resistance to abrasion makes it suitable for repeated model trimming and restoration fabrication without compromising integrity.
Application Scenarios
- Fabrication of crowns, bridges, and inlays/onlays
- Production of partial and full denture models
- Orthodontic study models and retainer fabrication
- Surgical guide model preparation
- Educational training for dental students
Instructions for Use
- Measure 24-26 ml of distilled water in a clean mixing bowl.
- Gradually sift 100g of Dental Stone Type Ⅲ into the water, allowing the powder to settle without stirring.
- After 1-2 minutes, mix gently with a spatula for 1-1.5 minutes until a smooth, lump-free consistency is achieved.
- Vibrate the mixed stone into the impression tray to eliminate air bubbles, then pour into the impression immediately.
Cautions
- Avoid using tap water as minerals may affect setting properties.
- Store in a cool, dry place away from direct moisture.
- Wear protective gloves when handling powder to prevent inhalation.
Storage
Store Dental Stone Type Ⅲ in its original sealed container at temperatures between 15-25°C and relative humidity below 60%. Do not expose to moisture or extreme temperatures, as this may compromise setting performance.
