The files become very large.Generally, the following applies: As many optical impressions as necessary,but as few as possible.6.3.1 Image field of the preparationDescription of individual teethOptical impressions can be made of the prepared tooth/teeth in the imagefield of the preparation.Angled optical impressionsAngled optical impressions are expedient here as well.6.3.2 Image field of the occlusionDescriptionIn the image field of the occlusion, optical impressions of a previously existingor of a waxed-up occlusion are possible.The image field of the occlusion must agree with the image field of the preparationin the mesial and distal region.CERECEven if you are not using the design technique "Correlation", an occlusal exposurecan be performed here as a design aid. This optical impression canbe displayed as a reference image during the design process.59 56 458 D 3344D 3344.208.05.14.02 04.2011 89
