Question 1

During AI segmentation, can I change the tooth number if the tooth number is not correct in the contour stage?

Accepted Answer

Yes, you can. Please click the tooth number that wants to change, and the tooth number selection window shall be displayed.

Question 2

During AI segmentation, can I add teeth manually if I can’t find some teeth in the contour stage?

Accepted Answer

Yes, you can. Please click “Add” button below.

Question 3

AI segmentation shows a failure message during segmentation. What should I do?

Accepted Answer

There are several causes that AI segmentation shows a failure message.

First, if the reorientation is not correct.
Second, if the internet connection is temporarily unavailable.
Third, if the AI server does not respond correctly.

You may try it after confirming the cause.

If you continuously receive a failure message, you can manually segment the teeth.

Question 4

What is different if I change the join value in the contour stage?

Accepted Answer

If the contour distance of the adjacent teeth is within the join value during segmentation, it segments the distance from the adjacent teeth to ‘0’.

Question 5

The “Hole ~ ~” message is displayed when entering the segmentation stage. Why and what should I do?

If the teeth are segmented based on the contour line, the teeth are not separated into one mass but are attached to the adjacent teeth. For example, the contour line passes into the black triangle and the upper part of the teeth is attached to the adjacent teeth.

To prevent this case please adjust the contact line to the upper part of the teeth so that the connection with the adjacent teeth is cut off.

If you continuously receive this message, there is an abnormal form of data that is difficult to distinguish by the eyes. Please contact us at https://www.ezdentone.com/contact

Question 6

Should I set the axis of all teeth in the axis stage?

Accepted Answer

You do not need to set it. The axis is automatically set for each tooth, and there is no need to be set for clear aligners.

However, if you use the autoalign function for consultation, you should set it to the correct position.

Question 7

What are the axis-setting principles in the axis stage?

Accepted Answer

Anterior: The center is the center of the tip, and the direction is the center of the root in the center of the tip.
Posterior: The center is the central fossa, and the direction is the center of the root in the central fossa.

Question 8

If there is a very fine spacing (ex. between #12-#13), can I segment the teeth to have a fine spacing if the teeth are attached to the scanned file?

Accepted Answer

Please set the value of join to ‘0”, and set the contour correctly to be located on the boundary of the teeth.

Question 9

I want to change the shape of the roots after segmentation. What can I do?

Accepted Answer

You can not change it after segmentation.

If you want to change the shape of the roots, please back to the axis stage. You can create the desired root shape by changing the axis.

Question 10

I have already separated the anterior teeth. Can I segment the posterior teeth additionally?

Accepted Answer

Yes, you can. Please select “Modify” from the notification window displayed when clicking the segmentation menu, and segment the posterior teeth.

Question 11

Do I have to segment all teeth?

Accepted Answer

No. You do not need to segment all teeth. If you are doing only anterior six, then you can segment only 6.

Question 12

If I segment the crowded teeth, the shape of the adjacent surface becomes bumpy. How to improve it?

Accepted Answer

You can improve it. The “Edit Tooth” menu can be used to improve the protruding or caved part of the segmented teeth.

Question 13

How is FA POINT/FACC used?

Accepted Answer

Used to calculate the torque/tip value of each tooth. It is also used to apply the “Auto Align” function of the setup tab.
