Product and material quality significantly influence the long-term clini- cal outcome. From a clinical perspective, important aspects to consider include long-term stability in the oral cavity, bio-compatibility, post-processing options (for example, type of veneering material), reasonably low costs and clinical versatility. While the aesthetic potential was initially due to using high-strength all-ceramic restorations, the true benefit of Y-TZP/ZrO2 (yttria-stabilised polycrys- talline tetragonal zirconia), for example, is its excel- lent bio-compatibility paired with flexural strength values that allow for application in any area of the oral cavity for both natural teeth and dental im- plants. When in close contact with the surrounding tissues,thereducedplaqueandbacterialaccumula- tion, as well as the development of currently unde- fined pseudo-attachments leads to long-term tis- sue stability around these components (Figs. 6 & 7). Thisfactmakeszirconiaproductstheprimarychoice not only for non-compromised clinical situations, but also for pre-existing periodontal conditions whenever restorations, such as implant abutments, are in close contact with surrounding tissues. Despite these advantages, it is important to understand and respect the material properties of these materials. If inadequate space or extensive leverage arms are unavoidable, alternative mate- rials should be selected. Advanced systems such as the NobelProcera system (Nobel Biocare) offer Figs. 2a–3c_Efficient CAD/CAM systems support the dental technician (NobelProcera System software, Nobel Biocare) by providing automated tools for anatomic framework design (Figs. 2a–c) and in manufacturing the ready-to-use components to eliminate any alterations after sintering (Figs. 3a–c). Figs. 4a & b_Shaded zirconia (NobelProcera Bridge Shaded Zirconia, Nobel Biocare) guarantees maximum strength combined with excellent aesthetic results and application of any veneering material within the CET range of zirconia.
