Trial summary

Patients need laminate veneer for their teeth usually use Emax CAD as an etchable ceramic. Yet fracture may occur so a stronger material is needed. Vita Suprinity is a recent material with glass ceramic enriched with zirconia (approx. Read more about this study

About this study

Patients need laminate veneer for their teeth usually use Emax CAD as an etchable ceramic. Yet fracture may occur so a stronger material is needed. Vita Suprinity is a recent material with glass ceramic enriched with zirconia (approx. 10% by weight) that offer practices and laboratories a high-strength, zirconia-reinforced lithium silicate ceramic (ZLS) and can be used to fabricate laminate veneers but the investigators have to know clinically it is fracture resistance, so the investigators are going to have Parallel groups in a randomized clinical trial.

Questions about this trial

What is this clinical trial studying?

A study testing Vita suprinity and Emax CAD in people with Tooth Discoloration, run by Cairo University.

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 6 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 21 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

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?

Fracture resistance assessed by clinical evaluation using dental mirror and probe according to the modified united states public health criteria (time frame: 1 Year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02940717, which also lists 3 linked publications.

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 21 Jul 2017; AzTrials last refreshed its copy on 8 Nov 2026.
