Overview: This article explains how to use Dandy’s recommended twist techniques to capture dental data in interproximal areas, contact points, and posterior surfaces.
Capturing Data in Difficult Areas
Dandy’s recommended twist techniques help practitioners capture images of interproximals, contact points, and posterior mesial or lingual surfaces. These techniques are essential when the practitioner is scanning a preparation site.
Identifying Missing Data Patches
After the practitioner scans the preparation and marks the tooth, the scanning system identifies areas where data was not fully captured. If the system identifies issues, the practitioner should select the Jump to Issue button for a detailed view. Any missing data in critical areas must be filled before the practitioner submits the order.
Twisting for Lingual and Buccal Surfaces
Practitioners should follow these steps to capture lingual, buccal, and distal surfaces:
Position the scanner along the occlusal surface.
Roll the scanner slowly until the scanner head is flat against the lingual or buccal surface.
Rotate the scanner approximately 45 degrees.
Twist the scanner in one direction and hold for two seconds.
Twist the scanner in the opposite direction and hold for two seconds.
Twisting the scanner directs light into difficult areas. Holding the scanner allows the camera sufficient time to capture data.
Capturing Mesial and Distal Contacts
To capture contact points specifically, use the following steps:
Position the scanner flat along the occlusal surface.
Rotate the scanner 90 degrees while the scanner is outside of the patient’s mouth.
Twist the scanner in one direction and hold for two seconds.
Twist the scanner in the opposite direction and hold for two seconds.
Using a monitor during this process allows the practitioner to see missing data fill in as the scanner angles change.
