Dentistry has warily accepted the long-promised infusion of technology. Based on technology borrowed from the aerospace, automotive, and even watch-making industries, this technology is now widely recognized due to its advantages of greater speed, precision, and efficiency without compromising quality. Today’s chairside and laboratory-based computer-aided design/computer-aided manufacturing (CAD/CAM) systems are used to design and manufacture metal, alumina, and zirconia.
This case demonstrates the benefits of digital dentistry in restoring an endodontically treated tooth with a deep mesial margin.
Starting with an x-ray. A deep secondary decay under an old amalgam filling with pulpitis symptoms were the diagnosis for this case.
Straight after endo completion and core placed. Tooth preparation was not yet completed.
Tooth preparation completed. Note the deep mesial margin managed using retraction cord.
Tooth preparation scanned using CEREC Primescan. Plus, the crown was designed using CEREC and was milled in Primemill.
Finished milled stained and glazed crown post processing. All done inhouse.
The E.max CAD A3 MT was now ready to be cemented.
Intaglio surface of the restoration before acid etching.
E.Max restoration was etched using hydrofluoric acid etch 5% for 20 seconds.
Ceramic silane primer applied, air dired, then Panavia V5 system was used for cementation.
Final restoration placed.
Modern digital dentistry has made restoring teeth more reliable and predictable than ever before.
