Thank you for your interesting presentation. Is there any way to improve the fit in the deepest part of the post?
Thank you very much for your very useful presentation.
In this study, it seems that you did not assume a space for the keeper to be installed.
For clinical applications, is it possible to give the keeper built-in space?
Thank you for the intriguing presentation.
Titanium is known as a difficult-to-cut material, did you use new tools every time when fabricating copings? There's a risk of decreased fit accuracy due to tool wear if you continue fabricating with the same tools for 2 or 3 consecutive pieces.

Thank you for your question.
We are thinking of adding width and roundness to the post by abutment tooth preparation.
However, it is also possible that the software deliberately makes it incompatible in consideration of the lifting by cement when the root coping is attached.

Thank you for your question.
It seems difficult in the "Post & Core" mode of the currently using software, but it is possible in the "Inlay" mode. However, there seems to be a limit to the length of the post part. We have already made one sample.

Thank you for your question.
In this study, when making the root coping, we replaced it with a new bar. However, since all five pieces are shaved using a same bar, there is a possibility that the accuracy will decrease. We will consider it in the future.
