Official Title:
Brief Summary: To evaluate the clinical performance and survival rate of NobelProceraTM Bridge Shaded Zirconia on natural teeth in the posterior region for a period of 5 years. The working hypothesis of this clinical study is that industrial centrally produced 3- or 4-unit bridges of shaded yttrium-oxide partially-stabilized (Y-TZP) zirconia (NobelProceraTM Shaded Zirconia) in combination with a veneering ceramic material will show sufficient CDA ratings (80% R+S) and a sufficient survival rate (93%) after 5 years in comparison with a reference level of 95%.
