12 I I CE article _ litihium disilicate restorations _In today’s fast-paced world, instant gratifi- cation is expected to be synonymous with worth- while results. This also applies to dental treatments. While there have been many recent technological innovations specifically for chairside restorations, dentists have faced complications when mastering complex and time-consuming protocols. The E4D Dentist System (D4D Technologies) eliminates those obstacles by providing outstand- ing clinical results in a single visit using intuitive, efficient and state-of-the-art technologies. The E4D Dentist System’s three-dimensional software simplifies designing and milling multiple restorations. This provides dentists with more con- trol over the aesthetic process. The E4D in-office CAD/CAM system is equipped with a high-speed intraoral laser scanner for capturing digital im- pressions, which provides restorations with better- quality fit and function because it incorporates intraoral digital impressions, traditional impres- sions and models. The E4D Dentist System streamlines work for dentists, who gain the enhanced confidence of producing reliable restorations for every patient case. Meanwhile, patients receive both enhanced and more efficient care with faster treatment times. Contributing to efficiency and accuracy is the E4D design software, which facilitates required modifications to finalize restorative designs in record time. Restorative designs are then sent to the E4D precision milling unit, which incorporates dual spindles and diamond burs to efficiently form CAD materials into restorations that exhibit exception- al fit, maximized strength and lifelike aesthetics. In fact, restorations fabricated using CAD/CAM processing have demonstrated less chipping or fracturing,whichenhancesthepredictabilityofthe restoration.1 Among the materials that can be processed chairside with the E4D Dentist System is lithium disilicate (IPS e.max CAD, Ivoclar Vivadent), which is available for processing CAD/CAM restora- tions indicated for placement in the anterior and posterior.
