The “wave” technique was then used to cure the excesscementtoagellikestate,whichenabledeasy removal (Fig. 14). Excess cement was removed from interproximal and cervical areas using a microbrush, after which complete polymerization was achieved by curing from the buccal, lingual and distal aspects. _Conclusion Thecombinationoflithium-disilicateblocks(IPS e.max CAD) and the E4D Dentist System is a state- of-the-art material and technology solution that enhancesthepredictability,aestheticsandease-of- useofin-officeCAD/CAMprocedures.Restorations completed with this complementary combination demonstrate excellent fit, function and aesthetics (Figs. 15 & 16). As a result, dentists can provide progressive, one-day treatments to patients, elimi- nating more invasive and time-consuming proce- dures that can require multiple appointments. By incorporating the essential components of smiledesignandaccuratescanning,theE4DDentist System helps to ensure the accuracy and pre- dictability of resulting restorations. When milled from highly esthetic lithium-disili- cate blocks (IPS e.max CAD), the restorations enable dentists to provide exceptional treatments tailored to the patient’s authentic esthetic characteristics._ Editorial note: A complete list of references is available fromthepublisher.
