Unable to Download "Open Dental CAD" add on tool for Blender

I am unable to download “Open Dental CAD” add on tool for blender. i have tried this link “https://sites.google.com/site/blenderdental/get-started” but it shows that add on is in transition stage.

Please help on urgent basis

I doubt you’ll get help here if addon is taken down.
From the site:
“…Feel free to browse around, download the application and try some of the demos and tutorials. If you have any questions, please feel free to comment on the site here or send me an email personally.

BTW, the last announcement on that site was from March 2011…
I think it’s safe to assume that this addon was abandoned.
