All-ceramic restorative systems provide outstanding esthetics and biocompatibility at optimal function. With the introduction of a new sintered glass-ceramic as veneering material for a tremendously improved heat pressed lithium di silicate substructure glass-ceramic as well as for zirconium dioxide framework ceramics, a new era in the combination of mechanical and optical properties of all-ceramic restorations has been initiated. This new concept fulfills highest esthetical and mechanical demands for the major part of fixed prosthodontic clinical situations, and enables an harmonious esthetical appearance of different types of all-ceramic frameworks. The combination of these new materials offers significantly increased range of indications covering veneer-, inlay-, and crown technique, as well as different types of fixed partial dentures including heat pressed lithium di silicate glass-ceramic substructure material, and frameworks made of zirconium dioxide ceramics.
The optical performance and excellent fit of the new heat pressed lithium disilicate substructure glass-ceramic structure combined with the adhesive cementation technique facilitates innovative, tooth structure preserving preparation designs offering a whole new era of treatment options like resin bonded wing-retained and inlay-retained fixed partial dentures. Ingots are available in a wide range of opacity and translucency enabling an outstanding esthetic result.
The team lecture will provide details of the development of this new all-ceramic generation and will demonstrate proven treatment concepts for the clinical use based on the results of a three-year clinical study with these materials.
