About this study
Official title: Esthetic Outcome of 3D Printed Hybrid Ceramics as Final Restorations for Single Screw Retained Implant. A Clinical Randomized Clinical Trial
clinical trial
The goal of this clinical trial is to record the esthetic outcome of the 3d printed hybrid resin crowns. It will also test which method of fabrication is advantageous than the other one. The main questions it aims to answer are:
Does any of the fabrication methods differ in its esthetic outcome?
Researcher will compare 3d printing fabrication to conventional fabrication method which is the milling technique to see if 3d printing of hybrid resin serves patients a better crown's esthetic outcome.
Participants will:
Receive a crown after implants are osseointegrated Visit the clinic once every 3 months for checkups and tests Keep records of level of patient's satisfaction.
- Conditions
- 3D Printing
- Being tested
- 3D printed hybrid resin ceramic crowns, milled hybrid resin ceramic crown

Questions about this trial
What is this clinical trial studying?
A study testing 3D printed hybrid resin ceramic crowns and milled hybrid resin ceramic crown in people with 3D Printing, run by International Dental Contiuing Education.
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 7 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: opening soon, as of the sponsor's last update on 4 Sep 2025. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Nourhan Gamal Dr.Nourhan Gamal AbdEl-Aziz, Master holder (01064249441, nourhannegamal259@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Aesthetic appearance (time frame: 6 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 4 Sep 2025.
