Completed
Conditions
Zirconia Based Fixed Dental Prostheses
Registration Number
NCT02220764

Brief Summary

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.

Detailed Description

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

Primary Outcome Measures
NameTimeMethod
Number of Fixed Dental Prostheses (FDPs) With Failure3 years

"Failure" was recorded if there was a need to remove the Fixed Dental Prosthesis over the observation period.

Secondary Outcome Measures
NameTimeMethod
Number of Fixed Dental Prostheses (FDPs) With Chip/s3 years
