54 Chapter 7 Acquiring a 3D Model for Orthodontics
Half of a dot (only one arch, upper or lower) indicates a partial buccal bite. The example below
shows that one-half of a buccal bite image has been acquired. Note the green box on the teeth on
the upper jaw. To complete the bite, acquire the teeth on the opposing jaw, directly opposite of the
green box.
To complete a partial buccal bite image, move the CS 3500 slightly more gingival, toward the
missing arch, and ensure that there is at least a 30% overlap between the second buccal bite
acquisition and the previous one.
Once both arches are displayed in the Acquisition interface, the bite image is successful, and you
can acquire additional bite images, which will increase the accuracy of the bite.
4 Acquire several additional buccal bite images. You can take up to six bite images for a full arch.
5 Once the bite has been registered, rotate the model and zoom the view to ensure that the bite is
accurate and that there are no areas where the bite is mismatched. Click a dot to view the bite for
that acquisition.
Tip: If you need to acquire a second buccal bite image because an
opposing arch is missing, always move toward the opposing arch with the
CS 3500.
Important: For a full arch, you should acquire at least four buccal
bite images—one on each side of the mouth at the molars, and one
on each side of the mouth at the canines.
