Several products from the Initial ceramic system from GC have been used to achieve the beautiful crowns in this video. They can also be used for other types of ceramic restorations, such as veneers, inlays, onlays, etc. Initial LiSi is a highly aesthetic feldspar veneering ceramic adapted to the light-dynamics of lithium disilicate frameworks : https://www.gceurope.com/products/initiallisi/ For the framework, the lithium disilicate glass ceramic Initial LiSi Press was used: https://www.gceurope.com/products/initiallisipress/ For further characterization, the painting solutions Initial Lustre Pastes NF and Initial Spectrum Stains can be used: https://www.gceurope.com/products/initiallustrepastes/ https://www.gceurope.com/products/initialspectrumstains/ In this video, a bio-aesthetic layering approach is shown; however, the ceramics can be used in various techniques (Classic – One – Posterior), as shown in other videos. Preparation and wash firing The LiSi Press copings are shaped and prepared. The palatal surface remains full anatomical up to the incisal third to improve the stability of the restoration. The required wash firing can be done with Initial Lustre Pastes NF or Initial LiSi powders. First firing Fluo Dentins are layered over the incisal refractive edge. The central and cervical area is covered with chromatic INside powders to mimic the dentin core. If required, an intermediate firing can be done to fix the inner structure. Second firing Use Dentin powder to model the final dentin structure. Mamelon structures are highlighted with Fluorescent Dentin FD-91 and their chroma is adjusted using INside powders or Spectrum Stains. Continue with applying a thin layer of Clear Fluorescence evenly over the entire dentine body. Bluish or greyish Enamel Opal is applied in the incisal or approximal are, alternatively Opal Booster can be used. Use different Enamel and Transpa materials next to each other to achieve a lifelike effect in the incisal area. The final shape is built up with a mixture of Enamel, Enamel Opal or EOP Booster. Enamel Occlusal and INside powders can be used to create a halo effect. The incisal edge remains open and the Dentin and CL-F layer are left uncovered to guide more light into the inside of the restoration. Finishing and glazing If needed, the Enamel-Opal mixture from the previous firing can be used to do corrections. Corrections in the cervical area are done with a Dentin-Enamel mixture of Cervical Transclucent powders. The high degree of vitality, fluorescence and opalescence give the final restoration a very natural appearance after glaze firing. Step-by-step by MDT Michael Brüsch
