Ghost Mode One

Ghost Mode is a procedure for the single-visit treatment of multiple restorations. It requires at least two CEREC Omnicam devices to work, and allows the dental technician’s workflow to run in parallel with that of the dentist. The base idea is that the Biocopy scan of each subsequent Omnicam would be inherited from the Preparation scan of the previous Omnicam. Under this procedure, while the dental technician is designing the restorations for the anterior region, it is possible for the dentist to continue preparation and scanning of the posterior region. For treating a larger number of teeth, utilizing Ghost Mode can save a considerable amount of time, of which is the essence of single-visit restoration.

The patient’s initial state. The eight upper anterior crowns were veneered zirconia, with #22 previously RCT. The facets on the four lower anteriors disoccluded with the uppers, and were previously unfinished veneer preparations, according to the patient.
The four upper anterior crowns were removed in preparation for the mock-up.
Mock-up of the upper arch. The patient wanted white, but more “natural-looking” teeth and thought that her original restorations were too long. She also wanted the new restorations to be less angular, and with smaller black triangules.
#14 – #24 prepared and scanned. At this point, I have cycled through three Omnicams.
#44 – #34 prepared and scanned. I opted not to use the Ghost Mode procedure for the lower restorations, so all eight abutments were scanned into one Omnicam. The distal side of #42 was prepared more aggressively due to proximal caries.
I always try to double check the margins on my veneers due to the unforgiving nature of CNC milling. With proper contours, the veneers can be seated into place with minimal adjustments, as it was with this case.

Two-week follow up of the final restoration. The ceramic used was the VITA Triluxe Forte.

Practice vs Theory

My short conclusion is that Ghost Mode, without a doubt, drastically improves the speed and efficiency of single-visit restorations that dentists can achieve. However, being enabled and actually doing something is not the same, and my impression is that this technique, like everything else, needs a lot of practice and training. More importantly, it requires a mutual understanding between the dentist and the dental technician so that important details, such as how to divide the scanning regions, can be refined and optimized.
