Imaging with the Omnicam

I want to pass on something that I have noticed when imaging with the omnicam. I think it is very important to start and end your imaging with the camera starting on the occlusal table. I usually teach people to start on the posterior occlusal and move toward the premolars/canine while some like to start on the premolars and work back. Once you image the arch from the occlusal begin to rotate the camera toward either the buccal surface or lingual. Don't move too quickly. Take your time to be able to get the camera facing perpendicular to that buccal surface and work your way along that entire surface gathering all the necessary tooth data as well as a few millimeters of gingival tissue below the height of contour. This will help with the stitching of the buccal bite later. Once you complete the facial data aquistion, begin to roll that camera slowly over the occlusal table and move it to the lingual and gather all the necessary lingual tooth and gingival information. It is not as imperative to get every last bit of data on the lingual. Make sure the margins and the interproximals have all the captured data necessary. When the lingual is finished, roll the camera back to the occlusal table and finish there. By starting and finishing on the occlusal table, the models will tend to be in a better position when doing the buccla bite stitch and not rotated sideways which leave for a lot of manipulating of the model. Rolling of the camera to the buccal or lingual after the initial gathering of occlusal data is personal preference, but just remember....start and finish on the occlusal table and get some gingival info. The faster you can accomplish this, the less info the machine has to process all that data and the faster things will go both in capturing the info and the computer putting it all together.
