About this study
Official title: Randomized Clinical Study for Printed Definitive Hybrid Resin Implant Crowns: Short-term Effects of Surface Finishing and Wear
The goal of this clinical trial is to assess the clinical performance of printed resinous implant crowns with two surface finishing protocols-mechanical polishing versus glazing. Qualitative performance will be checked by scoring systems.
The main questions it aims to answer are;
- Do printed resin implant crowns clinically succeed in the sort-term?
- Do mechanical polishing or glazing the crowns would be better for clinical performance?
Participants will:
- receive either mechanically polished or glazed printed resin implant crowns,
- visit at 6-months and 1 year for clinical check
Read the detailed description
Wear amounts of the printed resin implant crowns will be measured
- Conditions
- Surface Finish, Wear
- Being tested
- mechanical polishing, glazing
- Keywords
- glazing, mechanical polishing, printed implant hybrid resin crowns
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
mechanical polishingProcedure or surgery
mechanical polishing of implant resin crowns with polishing paste and discs
glazingProcedure or surgery
glaze liquid application followed by light-curing of the resin implant crowns
| Study group | Role | What they receive |
|---|---|---|
| mechanical polishing | Active comparator | surface finishing with mechanical polishing Receives: Procedure: mechanical polishing |

Questions about this trial
What is this clinical trial studying?
A study testing mechanical polishing and glazing in people with Surface Finish and Wear, 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 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: finished, as of the sponsor's last update on 8 Aug 2025. 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?
printed resin implant crown survival (time frame: From enrollment to the end of treatment at 6 months). The study lists 2 primary outcomes in all. 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 8 Aug 2025.
