An interventional study of Teeth abutment and Implant abutments in Zirconia Based Fixed Dental Prostheses, sponsored by Technische Universität Dresden. Completed. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2015-03-24.
Sponsored by Technische Universität Dresden · Not applicable, Interventional, and Treatment
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.
The study aims to provide evidence regarding the clinical behaviour of long-span tooth- and implant-supported FDPs.
Technische Universität Dresden is the lead sponsor of 237 studies on the registry; 45 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:

Number of Fixed Dental Prostheses (FDPs) With Failure
"Failure" was recorded if there was a need to remove the Fixed Dental Prosthesis over the observation period.
Time frame: 3 years
Number of Fixed Dental Prostheses (FDPs) With Chip/s
Measurement of the amount of fractures of the veneering material 6,12,18,24,30 and 36 months after placement of the restorations. The percentage of chips for the implant- and tooth- supported restorations will be reported.
Time frame: 3 years
Number of of Fixed Dental Prostheses (FDPs) With Rough Surface
Measurement of the restorations with rough surface 6,12,18,24,30 and 36 months after placement of the restorations.
