Smile Design with Primescan and CEREC 5.0 Software Mike Skramstad, DDS
A 58-year-old female presented for an esthetic consultation. She had been self-conscious and wanting to fix her smile for years. She had generalized wear, old defective/stained restorations, and improper tooth shape/position (Figure 1).
Figure 1.
A treatment plan of eight full coverage crowns was accepted by the patient. Crowns were recommended over veneers due to all the restorative material that needed to be removed and more importantly, the need to change the tooth position. All photographs, diagnostic records and a diagnostic waxup were completed for this case based on the principles of facially generated treatment planning.

At appointment #2, the upper eight teeth (5-12) were prepared for full coverage restorations (Figure 2). A full arch scan was completed of the upper jaw (preparations), lower jaw, buccal bite, and diagnostic waxup with the CEREC Primescan. fter processing the models, the first model that you see is the full upper arch with all eight preparations auto-marginated (Figure 3). This automatic feature of the CEREC 5 software is an incredible time saver… not only is the scanning incredibly fast, efficient and accurate, the software and its artificial intelligence automatically does much of the work for you.

The next step is to get the proposals (Figure 4 and 5). Not only is the CEREC 5 software automated with many of the steps, the algorithms that control the proposals are much improved. This design (based on a diagnostic waxup) required minimal adjustments to contour. The restorations were then milled, stained and glazed (IPS e.max CAD MT) and bonded into place (Figure 6). The patient was ecstatic with the final results.
The CEREC Primescan and CEREC 5 software makes even the most advanced case simpler. The automatic margination of multiple preparations, clarity of the models, and ability to accurately scan full arches for better proposals/occlusion will make all dentist more efficient when doing larger cosmetic cases.
