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. John W. Farah, DDS, PhD, and Santine Anderson, DDS, are lecturing nationwide on CAD/CAM technology. Joining with Robert Wisler, CDT, they have been lecturing 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, John M. Powers, PhD, and Ron Yapp, MS, 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, Cadent, D4D Technologies, and Sirona. We are also proving education and training at THE DENTAL ADVISOR for dentists, laboratory technicians, and sales representatives.

This issue of THE DENTAL ADVISOR will focus on the ever-changing world of CAD/ CAM. We will review all of the chairside systems, provide tips for choosing the right system for your practice, present clinical tips for using the systems, as well as protocols for success in CAD/CAM. In addition, the role of the laboratory and milling center and the concepts of closed and open architecture systems will be discussed. Finally, materials for use in CAD/CAM will be discussed along with clinical tips and information on training and support.CLICK HERE TO READ THIS ARTICLE

E4D - Design of Multiple Restorations
E4D Dentist is a complete chairside scanning, design and milling system. It has the capability to scan an entire arch and design up to 16 restorations. DentaLogic Software and Autogenesis allow the design of multiple restorations simultaneously in the same screen. A restoration does not need to be completed or virtually seated before the design of the next restoration. The following article outlines the preparation, scan and design of three restorations in the same quadrant.DOWNLOAD THE FULL CLINICAL CASE REPORT
Preparing for Success with CAD/CAM
CAD/CAM dentistry is allowing us to provide better dental care to our patients. An accurate digital image of the prepared tooth and adjacent teeth has the potential to be inherently more precise than a traditional impression material poured into a stone model and trimmed. The long-term success of the ceramic restoration, however, is dependent on tooth preparation and material selection. This report will offer preparation guidelines for successful all-ceramic restorations using CAD/CAM dentistry, the E4D Dentist system and diamond burs.DOWNLOAD THE FULL CLINICAL CASE REPORT
Scanning from a Final Impression with E4D Dentist
A 50 year-old man presented with recurrent decay under a gold crown on tooth #30. A core and full-coverage ceramic crown was the recommended treatment as it allowed optimal support for the tooth and resistance to fracture. The ability of E4D Dentist to scan a final impression allowed utilization of the system and optimal material selection while minimizing the patient’s chair-time.

In-office Chair-side Scanning and Milling with CEREC 3D and E4D Dentist
This article focuses on the in-office chair-side systems, CEREC 3D and E4D Dentist. To date, dentists at Enspire Dental have placed over 100 CEREC 3D and E4D Dentist ceramic restorations. This article is a brief update on each system based on their experiences. DOWNLOAD THE FULL CLINICAL CASE REPORT
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. DOWNLOAD THE FULL CLINICAL CASE REPORT.
Comparison of the Fit of Crowns Based on Digital Impressions with 3M ESPE Lava Chairside Oral Scanner C.O.S. vs. Traditional Impressions
The 3M ESPE Lava™ Chairside Oral Scanner C.O.S. is used to capture high accuracy digital images of teeth. Data from the scan was used to create traditional (PFM) or CAD/CAM zirconia copings and an articulated stereolithography (SLA) model that a milling center and a dental laboratory use to design restorations such as crowns, inlays, onlays, and bridges, veneers and seated implant abutments..
