Figs. 22 & 23 Final view of digitally designed and milled IPS e.max CAD anterior restorations, showing excellent fit, form and natural-looking esthetics. Conclusion This article has provided an overview ofthe possibilities of digital smile design, using computer design software, for the design of the milled diagnostic wax-up, the milled provisionalrestorations,andthefinalmilled ceramic restorations. CAD/CAMtechnologyshouldnotbere- gardedasmeremachinerytofabricatefull- contour ceramic restorations or frame- works; digital dentistry represents a new waytodiagnose,plantreatment,andcreate functional, esthetic restorations for pa- tients in a more productive and efficient manner. CAD/CAM dentistry will only further enhance the dentist–assistant– technicianrelationshipaswemovetogether into this new era of patient care. Automation has been slow in coming to dentistry and although new equipment has been introduced to make our work easier, we still create complex dental prostheses using old techniques. Even though the lost-wax technique is still a tried-and-true methodoffabrication,therewillcomeaday in the nearfuture when all frameworks and full anatomical crowns will be designed on computer.Onlythenwillwetrulyrealizethe wonder and power of dental CAD/CAM technologythatwasintroducedsolongago. Acknowledgments The clinical dentistry shown in this article was performed by Dr. Swann. The digital and technical dentistry was performed by Mr. Culp. Competing interests Mr. Culp receives an honorarium from Ivoclar Vivadent. Prof. McLaren and Dr. Swann declare that they have no com- peting interests regarding this article. “Once the provisional restorations had been approved, it became the technician’s responsibility to copy the temporary restorations in fabricating the final ceramic restorations.” Fig.20 Fig.21 Fig.22 Fig.23 Article_McLaren_00-00.qxp_Layout 1 02.03.16 20:49 Seite 5 Article_McLaren_00-00.qxp_Layout 102.03.1620:49 Seite 5
