FAQs
Q: Why is powdering necessary?
The CEREC camera takes a three dimensional image of the tooth preparation. It uses infrared waves which are sent down to the preparation and back to the camera to measure the heights of the tooth structure, adjacent teeth, and surrounding tissue. Non-toxic, titanium dioxide powder is applied to the preparations and neighboring teeth to ensure the waves bounce back to the camera in a uniform manner. Since dentin, enamel, and gingiva absorb the infrared waves at different rates, an unpowdered field will reflect the waves inconsistently and result in a picture that the CEREC 3D software cannot use.
Q: Are there tips for taking a good picture?
The "3 Ps" of successful CEREC use are Prep, Powder, and Picture. Taking the optical impression can be a little tricky in the beginning. Here are a few helpful hints for taking a good picture:
Make sure the preparation is in the center.
The image must be clear and focused.
Margins are visible.
Corners are visible.
The picture is taken from the path of insertion.
No powder "spikes" or areas of no powder should be visible.
