• Check for a bulge below the ideal contact area on the crown. Smooth down the bulge if necessary.
• Check contact areas on the adjacent teeth, looking for draw or bulges that can be smoothed out.

If the contact is light/open, verify margins, fit, and shade

Evaluate adjacent contact areas and adjust as necessary: 

• Parallel with the prep and with each other for draw 

  

• Broad contacts for ideal restoration(s)

• Rescan the prep and adjacent teeth only. (Note: tissue retraction is not necessary if the crown margins and fit were good.)

See step 4 of our Normal Case Protocol to see more details on which tools we recommend for contact adjustment.

• Double pack cord before scanning.
• If necessary, use a laser to expose the margins.
• Make sure the area is completely clean and dry, then rescan.
• For the best scanning results, leave both cords in for 5 minutes then remove the top cord (#02) immediately before scanning. Leave the bottom cord (#00) in while scanning.

• Send photos of the adjacent teeth with a full shade tab in view. The incisal edge of the shade tab should be lined up with the incisal edge of a tooth for the most accurate results. Watch out for bad glare.
• Provide additional information (calcification, incisal translucency, etc.) to help us accurately match the shade.

To assist us in determining a potential cause and solution for the fracture, please:

• inspect the prep for sharp edges.
• inspect the bite for sufficient clearance (we suggest 1.5mm).
• rescan the prep and bite and send us the new scans.

• Provide precise information regarding design preferences.
• Send photos and any additional notes with the case. Consider including drawings of your desired results (see example below).
• For highly esthetic cases, request screenshots or a 3D preview before the crowns are milled.

• Ensure the patient is biting in centric occlusion.
• Take a new bite scan and evaluate the alignment by comparing the scan to the patient's mouth.
• For implant cases:
  • take an x-ray to confirm the scan body is fully seated.
  • remove the scan body before taking the bite scan.
