    Measured: yearly up to 5 years

Secondary outcomes (1)
  1. survival rate of NobelProceraTM Bridge Shaded Zirconia on natural teeth in the posterior region

    Measured: yearly up to 5 years

Questions about this trial

What is this clinical trial studying?

A study testing NobelProcera Bridge Shaded Zirconia in people with Posterior Bridge Restoration, run by Nobel Biocare at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 30 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early (reason given: Business reasons). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

clinical performance of NobelProceraTM Bridge Shaded Zirconia on natural teeth in the posterior region with the proportion of patients with CDA ratings "R" (excellent) or "S"(acceptable) (time frame: yearly up to 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Mar 2017.
