About

The objective of this prospective clinical study is to investigate the differences in the complication rates between tooth- and implant- supported zirconia based fixed dental prostheses (FDPs) with at least 4 units. The null-hypothesis is that there is no difference in the complication rates between implant- supported and tooth- supported zirconia FDPs.

Full description

The study aims to provide evidence regarding the clinical behaviour of long-span tooth- and implant-supported FDPs.
