About this study
Official title: Clinical Follow-Up And Evaluation Of Porcelain Veneering Titanium Crowns Produced By Different Techniques
This clinical study aimed to evaluate the short-term clinical performance of porcelain-veneered titanium crowns fabricated using two different techniques: conventional casting and CAD/CAM milling. Restorations were assessed according to FDI clinical evaluation criteria with respect to esthetic, functional, and biological outcomes during follow-up appointments.Clinical evaluations took place at baseline (2 days after luting) and following 3, 6, 12, and 18 months after luting.
- Conditions
- Titanium Ceramic Crown, CAD/CAM Milling, Titanium Casting
- Being tested
- Casting Titanium-Ceramic Crown, CAD/CAM Titanium-Ceramic Crown
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Casting Titanium-Ceramic CrownDevice
Titanium-based ceramic crowns produced using conventional casting technique and cemented clinically.

Titanium-based ceramic crowns produced using CAD/CAM technology and cemented clinically.
| Study group | Role | What they receive |
|---|---|---|
| Casting Titanium-Ceramic Crown | Experimental | Participants received titanium-ceramic crowns fabricated using the conventional casting technique and were followed clinically during the observation period. Receives: Device: Casting Titanium-Ceramic Crown |
| CAD/CAM Titanium-Ceramic Crown | Experimental | Participants received titanium-ceramic crowns fabricated using CAD/CAM technology and were followed clinically during the observation period. Receives: Device: CAD/CAM Titanium-Ceramic Crown |
What is being measured
The primary outcome is the main question the study is designed to answer.

Questions about this trial
What is this clinical trial studying?
A study testing Casting Titanium-Ceramic Crown and CAD/CAM Titanium-Ceramic Crown in people with Titanium Ceramic Crown and CAD/CAM Milling, run by Ege University at 1 site in Turkey (Türkiye).
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 4 inclusion and 5 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: finished, as of the sponsor's last update on 10 Mar 2026. 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 Turkey (Türkiye). 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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 titanium-ceramic crowns evaluated using the Fédération Dentaire Internationale (FDI) World Dental Federation clinical criteria (time frame: Baseline, 3 months,6 months, 12 months, and 18 months). 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 10 Mar 2026.
