Take a careful and complete bite scan and verify it after the case renders. When taking a full bite scan, finish the scan pattern rather than stopping early.

When scanning a case, don't stress about non-critical embrasure spaces, non-critical lingual of the opposing, and data outside the gray box.

When scanning critical aspects of a case, capture the contact and occlusal aspects that need to be in contact with the restoration(s).

When scanning the margins, remember that tissue and tooth structure look the same to a scanner. Clean the margins with a micro brush.

Margins should always be clearly visible and distinct from the tissue or saliva in the scan: we recommend double packing cord and removing the top one before scanning.

Ensure the contacts and occlusion of the temporary have a precise fit. A thin articulating foil can help to check the details on contacts and occlusion.

Always evaluate the opposing and bite and check the occlusal clearance carefully.
Using the preop scan, cut out the prepped tooth and take a preliminary scan of the prep before packing cord.
Check scanner occlusal indicators for clearance.
When adjusting adjacent contacts:
1) Adjust with a fine, parallel diamond. Removing up to 0.25mm of enamel is safe.
2) Smooth with a fine, parallel, non-criscut carbide to keep the draw and breadth but also clean up the micro scratches from the fine diamond.
When prepping, adjust the adjacent contacts so they are parallel with the prep and with each other for draw and breadth.

For normal cases, take a preop scan:
// A preop scan lets you record the bite before the patient is numb.
// A preop scan gives you the data to more quickly check the occlusal clearance on the prep during the procedure.

When selecting the shade:
// Select the shade before taking the preop scan and prepping. Once the teeth dehydrate, you will not get a reliable shade.
// Take a picture with the shade tab(s) visible, lining up the incisal edge of the tooth with the incisal edge of the shade tab.
For successful restorations, use additional retention when needed. Well-placed grooves and box forms increase retention, especially on short preps.
