Acquire the antagonist.NOTICEImage field of the antagonistsThe image field of the antagonists must agree with the image field of the preparationin the mesial and distal region.5. Remove disturbing marginal information via "Design" / "Correct opticalimpressions..." (see "Correcting the orientation of bridges").6. To exit the acquisition process, click the icon marked "Next".6.1.9 Veneer imagesWith software V3.80 or higher, the exposure in the anterior tooth region doesnot differ from other exposures. Continue acquiring the preparation from theocclusal/incisal direction.6.1.10 Acquiring bridge preparationsAcquiring a 3-unit bridgeA Overlap area C 2. optical impressionB 1. optical impression D 3. optical impressionTo produce bridge frameworks of up to 3 elements, you can acquire the toothsituation with the CEREC Bluecam. Make sure there is always dental substancevisible in the overlap area of the acquisitions (areas A). Start by takingthe 1st scan on the distal end. Then guide the camera over the preparation inthe mesial direction.The design of bridge frameworks is described by means of an example under"Designing a bridge framework".6.1.11 Take castingemptyPrepare casting✔ In certain circumstances, the casting must be cut free somewhat, so thatthe definition of the image of the CEREC Bluecam is sufficient.59 56 458 D 334484 D 3344.208.05.14.02 04.2011
