Intra-Oral Scanning Tips
Anteriors
-
Capture the entire anterior region so that the restoration matches existing dentition.
-
Do a pre-prep scan of the tooth or temporary crown to aid in design.
Posteriors
-
Capture at least two teeth on either side of prepared tooth to ensure restoration fits within the existing dentition
Getting the Best Possible Scan
Moisture Control
-
Dry prep and adjacent teeth with air to eliminate distortion caused by saliva
-
Use cotton, saliva ejectors and other dental absorbents to keep mouth dry during scanning
-
Keep the camera of the scanning tip dry and clean at all times
Tissue Management
-
Adequate gingiva retraction, or use of a laser enables accurate scanning of the margin line
-
Subgingival margins are hard for the scanner to capture unless tissue management technique is precise
-
The two-cord retraction technique or use of a laser is highly recommended for a visible margin line
