Clinical Evaluation of Three-Dimensional (3D) Printing Resin Nanoceramic Crown Restoration.
Turkey (Türkiye)60 participantsStarted 2025-06-26
Plain-language summary
This study aims to evaluate the function and aesthetics of ceramic-filled hybrid resin permanent crowns produced by 3D printing method in posterior teeth according to Revised FDI criteria.
At the Department of Prosthodontics, Faculty of Dentistry, Ege University, 60 patients who present for single-tooth crown restoration in the posterior region of either the maxilla or mandible and who meet the inclusion criteria will receive a total of 60 permanent crown restorations. Following tooth preparation, the restorations will be fabricated using a three-dimensional (3D) printing technique with a ceramic-filled hybrid resin material (VarseoSmile TriniQ, Bego, Bremen, Germany).
The effects of restorations on clinical success will be evaluated according to demographic data (age, gender, etc.) and modified USPHS and Revised FDI criteria, and statistical analysis will be applied to the recorded data. Follow-up visits are scheduled at 0: baseline, 6, and 12 months.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
