About this study
Official title: Clinical Evaluation of Digitally Fabricated 3D Printed Palatal Crib Versus Conventional Palatal Crib: A Randomized Clinical Trial
The aim of this study is to evaluate clinically digitally fabricated 3d printed palatal crib versus conventional palatal crib
Read the detailed description
This study aims to evaluate the clinical performance of a 3D printed palatal crib as an alternative to the conventional palatal crib in managing persistent thumb sucking. The findings may provide evidence on whether digital fabrication offers comparable clinical effectiveness while simplifying the fabrication process and improving appliance customization
- Being tested
- Digitally fabricated 3D printed palatal crib

Questions about this trial
What is this clinical trial studying?
A study testing Digitally fabricated 3D printed palatal crib in people with Digitally Fabricated 3D Printed Palatal Crib, 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 4 inclusion and 4 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 2 Oct 2026. 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 Nourhhan Hamdy, Bachelor degree (01151201341, nourhan.hussien@dentistry.cu.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Success rate (habit stop) & patient satisfaction (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 NCT07856277, which also lists 10 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 2 Oct 2026.
