Color Dipping Zirconia Restorations: A Step-by-Step Guide

Step 1: Prepare the Restoration - Proper surface prep ensures the color solution penetrates and adheres evenly.

• Steam clean and air abrade restorations to remove contaminants.
• Finish to a high polish for smooth, even color uptake.
• Mask off areas not receiving color with liquid block-out resin.

• Handle only at the edges to keep oils from fingers off the surface.

  
  

Step 2: Select the Color - Choosing the right pre-made color solution is critical for natural, accurate shades.

• Assess the prepared tooth shade and neighboring teeth coloration.
• Pick a dipping solution that matches or slightly undershoots the target shade.

• For more vibrancy, combine two compatible color solutions.

Step 3: Immerse Strategicall - Controlled immersion is key to prevent overly dark or uneven coloring.

• Use flat-tip tweezers to dip the restoration inverted, contact area first.

• Start with a conservative 10 second dip, then check color and extend time as needed.

• Agitate gently while immersed to displace air bubbles and aid penetration.

• Maintain a consistent orientation; flip and turn the restoration to color all areas.
  

Step 4: Manage Depth of Color - Getting color depth right requires an iterative approach.

• If more vibrancy is needed, do short follow-up dips of 2-5 seconds.
• Dab a paper towel between dips to remove excess and better judge color.
• Focus extra dip time on darker chroma areas like incisal edges.

• Allow to dry fully between immersions to see true resulting color.

  
  

Step 5: Control Runback - Excess color solution can cause dark runback lines.

• Always dip with restoration inverted to use gravity to control runback.
• Gently shake off excess solution after each dip.
• Carefully dab any runback areas with paper towel or air burst.
• If needed, dilute the solution with distilled water by 10% to reduce runback.

Step 6: Final Cleanup and Firing - Remove residue and fix color with the final firing process.

• Rinse with clean water and air dry fully. Inspect for any remaining discoloration.
• Re-mask protected areas before firing. Use supportive firing pins and posts.
• Follow manufacturer’s firing guide for times, temperatures, and pre-drying.

• Polish and finish facial/interproximal areas. Seal restored tooth.
