This is important because this technology is increasingly being used nation wide.
Why this matters:
It's here to stay.
- Corporate mills, private practices, and national dental labs are adopting this because it's faster and cheaper--frankly insurance doesn't pay like it used to.
- Patients love one visit crowns.
New possibilities for patient treatment.
- If you can do something faster, cheaper, arguably better--why not?
- Less sensitivity--Milled restorations have much less shrinkage than composites and less thermal conductivity than silver.
- Quickly replaceable--break it? No problem. Mill a new one from a saved file.
- CAD/CAM is cool
Note: Gold is the very best restoration in existence.
- It lasts longer than a ceramic crown.
- It spares the enamel from the opposing tooth
- It will not fracture catostrophically
- But it costs over $1700 an oz.

Sorry for taking so long!
The community has been doing such a great job, that I couldn't think of anything of worth contributing until recently.
Feel free to PM me with any ideas you'd like covered.
Step 1: Capture A Reference
This model is made by taking an optical scan.
In the case of the BlueCAM (formerly state of the art), it involves stitching multiple images together.
For the OptiCAM (released late last year), the scanner creates a 3-D image by compiling from a video feed in live time.
- Start one tooth distal (to the back) to the main tooth to one tooth mesial (to the front of the prepared tooth).
- Have a steady hand.
- Capture the smallest area required. For the bluecam, try to have no more than 3 images to the model.
- Less data-> faster processing.
