Dust-free type ultra-hard gypsum that produces more dense and smooth model surfaces with various impression materials.

Dental Stone for Special Use

Includes ultra-fast hardening, low-expansion gypsum for articulator mounting, and high-expansion gypsum for resin denture models.

Frequently Asked Questions

  • Is there an expiration date for these products?Open
    Unopened products have a shelf life of 3 years in aluminum packaging and 2 years in paper bags. Once opened, store in an airtight container and use promptly to prevent moisture absorption and quality issues. You can check the expiration date of your product by looking at the numbers (year, month) following the hourglass mark (⌛) above the barcode on the product.
  • Are there specific measuring tools available?Open
    No. We recommend measuring by weight.
    Measuring gypsum by volume can lead to inconsistent performance.
    By weighing it, you can ensure consistent performance for anyone using it.
  • Can salt be added to accelerate hardening process?Open
    It is not recommended to use salt.
    Instead, increase the water temperature or the number of mixing cycles to speed up hardening.
  • Is there a white ultra-hard gypsum?Open
    No.
  • Is there a fast-setting type available?Open
    We do not have a fast-setting type that begins initial hardening in about 5 minutes.
    However, Hi-Mount, designed for articulator mounting, hardens in 3 minutes and 30 seconds and can be used as an alternative.
  • How can surface roughness on gypsum models be addressed?Open
    Surface roughness is often caused by delayed or insufficient hardening. Ensure precise weighing and mixing times, and follow specific steps to address potential issues from impression materials and handling techniques.

    Here are the main causes and solutions:

    • Cause 1:
      Some additives in alginate or agar impression materials can delay the curing of gypsum. Over time, these additives may seep onto the impression surface (a phenomenon known as syneresis), leading to insufficient curing and resulting in surface roughness on the gypsum areas that come into contact with the impression.

      Solution 1:

      • 1. Immediately rinse the impression surface with running water after taking the impression and shake off the excess   water.
      • 2. For alginate impression materials, spraying with Smooth Maker can be beneficial.
      • 3. Avoid leaving the impression exposed indoors for an extended period.

    • Cause 2:
      Some surfactants used in silicone impression materials (to prevent bubbles) can delay the curing of gypsum. When a significant amount of these surfactants remains on the impression surface, particularly in corner areas, the gypsum may not cure properly, resulting in surface roughness.

      Solution 2:

      • After using silicone impression materials, remove the surfactants by washing with water and then using air or similar methods to ensure thorough removal.

    • Cause 3:
      Saliva and blood contain components that can delay the curing of gypsum. If these contaminants remain on the impression surface, they cause insufficient curing and surface roughness in those areas.

      Solution 3:

      • 1.Remove saliva and blood using a soft brush.
      • 2.Use tissue paper twisted into a wick shape to absorb excess water from the corners.

    • Cause 4:
      If water remains on the impression surface after washing, it can prevent the gypsum from forming a dense structure, leading to surface roughness. Additionally, prolonged contact with water after curing can cause the gypsum to dissolve from the surface, resulting in roughness.

      Solution 4:

      • 1.After washing the impression, use air or similar methods to remove the water.
      • 2.Use tissue paper twisted into a wick shape to remove excess water from the corners.

    • Cause 5:
      Using a trimmer or steam cleaner on gypsum that has not fully hardened will cause surface roughness as it flakes off from those areas. A complete hydration reaction for gypsum requires 2 hours for regular gypsum and 3 hours for hard gypsum.

      Solution 5:

      • 1.Allow the gypsum model to set in a place where it won’t dry out for at least 2-3 hours before handling.
      • 2.Use a dry trimmer. If using a wet trimmer, cover at least the tooth model parts with wax.
      • 3. Avoid using a steam cleaner on the tooth model parts.
