Coded Scan Body Scan

Overview

After installing the coded scan bodies, Elite can assist users in scanning the scan bodies with intraoral photogrammetry (IPG). Complete and accurate data of scan bodies enables technicians to perform more precise designs for dentures. This article introduces the basic scan flow and strategy for scanning the coded scan bodies. 

How to scan coded scan bodies? 

STEP 1: Loop Scan

Start from the hexagon part of the coded scan body positioned at the posterior area. Next, continue to scan the opposite scan body along with the dots. Then, move to scan the remaining 4 coded scan bodies in turn along with the diagonal line. In this step, it is not necessary to scan all dots of coded scan bodies. 

STEP 2: Capture markers

Start from the first coded scan body in the last step. Scan the coded scan bodies in turn. Acquire complete surface dot data by reciprocating. Ensure the markers on the upper surface turn green, and all images of coded scan bodies have been presented on the window.

It is important to acquire clear data of 6 dots around the hexagon of each coded scan body in that the dots contain crucial position and angle data of the coded scan bodies. 

Tips: The status of markers

In general, the markers on the coded scan bodies have 3 statuses. 

Tips: Group Scan

Users can carry out group scans to alleviate the problem of limited oral space in the scan process. The group scan enables users to scan different HACS separately. 

E.g. Users need to scan HACS positioned at the 13^th, 23^rd, 16^th and 26^th positions, whereas the limited oral space cannot enable users to scan the HACS at the 13^th and 23^rd positions simultaneously. 

First, users can install the HACS at the 13th, 16^th and 26^th positions and scan these HACS with the above-mentioned methods. 

Second, users can click the plus button to add a group of scans. The software only supports at most 2 groups of scans. 

Third, users can remove the 13^th HACS and install another HACS on the 23^rd position, keeping the 16^th and 26^th HACS for aligning and transition in the following scanning. Please ensure the 13^th and the 23^rd HACS are not the same, otherwise, the HACS will be applied to the last scan data, the 23^rd position, with a precaution in conversion and mark. 

Fourth, in the second group of scans, users should select the substitution HACS, namely, the 13^th HACS, turning the HACS in orange.

Fifth, start scanning the 23^rd HACS. Please scan from the existing HACS, the 16^th or 26^th HACS and gradually transfer to the 23^rd HACS. 

After group scanning, users can head to the following steps.
