Introduced approximately seven years ago for posterior monolithic crowns, zirconia had a slight increase in translucency compared to the traditional high-strength zirconia used for crown and bridge frameworks. 7. }); They promote a soft-tissue response very similar to porcelain veneers; the tissue stays pink and stippled and healthy ( Figure 8). A lovely item to show a patient. Milled from monolithic zirconia, our full-arch implant bridge provides edentulous or soon-to-be edentulous patients with both strength and high-translucency esthetics.
