CAD/CAM Corner
THE DENTAL ADVISOR is leading the way in CAD/CAM dentistry. We are quickly becoming industry experts in this very exciting area of growth. Our Editor, John W. Farah, DDS, PhD, is lecturing nationwide on CAD/CAM technology. Dr. Farah and Robert Wisler, CDT, have been lecturing together to both dentists and laboratory technicians and have published several articles on CAD/CAM dentistry for publications such as the Journal of Dental Technology and Dental Lab Products. In addition, Dr. John Powers and Ron Yapp have completed research and are planning additional projects on the properties of ceramics and zirconia and their cementation.
Currently, THE DENTAL ADVISOR is working with a number of leaders in CAD/CAM dentistry, including 3M ESPE, D4D Technologies, and Sirona. We are also providing education and training at THE DENTAL ADVISOR for dentists, laboratory technicians, and sales representatives.

E4D Conservative Esthetic Restoration
A 52-year-old man presented with a large composite restoration on tooth #12. The rotation of the tooth and lingual extension of the composite restoration left insufficient support for the lingual cusp. A significant fracture was clinically visible. An E4D Dentist MODL onlay was selected as the most ideal treatment option after consideration was given to the preservation of facial esthetics, protection of the lingual cusp and elimination of concerns associated with a provisional.

CEREC 3D Onlay - Treating the Fractured Tooth
A 45-year-old woman presented in September 2008 with a chief complaint of a fractured upper left molar (#15). She was interested in repairing the tooth with a long-term restoration and expressed concern about loss of additional tooth structure. A clinical exam revealed a fractured distobuccal cusp and occlusal amalgam restoration on tooth #15. A radiograph revealed decay on the mesial of #15. There was no evidence of fracture in the remaining tooth structure or bruxism in the remaining dentition. A treatment plan for an MODB onlay was presented and accepted as a conservative, long-term treatment option.

Bond Strength of Resin Cement to Treated Zirconia
The purpose was to evaluate the shear bond strength of a self-cured resin cement to as-sintered zirconia prepared with different treatments under two storage conditions. The ceramic substrate tested was as-sintered zirconia (IPS e.max ZirCAD) with the following treatments: A –zirconia with Clearfil Esthetic Cement, B - zirconia with Clearfil Ceramic Primer and Clearfil Esthetic Cement, C – zirconia ground with a diamond bur with Clearfil Ceramic Primer and Clearfil Esthetic Cement, and D – zirconia sandblasted with Clearfil Ceramic Primer and Clearfil Esthetic Cement.
