HI-TECH WAX offers CAD/CAM diagnostic milling discs composed of pure opaque and translucent waxes that offer smooth milling, high accuracy, precise margins and excellent fit. The discs are strong, have smooth carvability, burn out clean and can be used with diamond or carbide burs. The discs allow you to repair defects with a digital spatula or Bunsen burner spatula just like conventional crown and bridge waxes.
