• Make a wax coping complete to the margin. Cut back the marginal circumference 1-4mm.(This creates the area for the margin to be completed with Authentic Pressable Cermamic)
• Invest with MICROSTAR HS INvestment and cast the wax up. Opaque and fire the metal coping.
• Wax the margin directly to the opaqued casting, 60-100% of the full anatomical form depending on whether you intend full layering or minimal build-up and stainign as the method of fabrication.
  (Minimum ceramic thickness: 0.8mm)
• Sprue, Invest, burnout and press with Authentic Pressable Cermaic to create the optimum esthetic foundation for the final restoration.
• Complete the functional and esthetic build-up using Authentic materials and techniques for layering, internal live staining, Micro-layering and direct staining.

Prep Requirements:

• Anterior and posterior crowns: shoulder or chamfer.
• Feather ege preps require a thin metal margin.

Critical Controls:

• Alloy thickness: not less than 0.3mm
  
• Ceramic thickness:
  Pressing: not less than 0.8mm
  Finishing: not less than 0.6mm
  
• Alloy Coefficient of Thermal Expansion (CTE)
  @ 600 C: 15.8 to 16.7 / Ideal is 16.0 to 16.4
  
• Cooling times for layering/staining/glaze firings depends on alloy used.
