Clinical Performance of 3D-Printed Resin and Zirconia Implant Restorations
Egypt60 participantsStarted 2026-04-01
Plain-language summary
This randomized controlled clinical trial evaluates the clinical performance of 3D-printed resin restorations compared with milled monolithic zirconia in implant-supported single crowns and short-span fixed partial dentures (FPDs). A total of patients requiring one or two implant-supported restorations in the mandibular anterior region were randomly allocated to receive either 3D-printed permanent resin restorations (CROWNTEC) or conventionally milled zirconia prostheses.
All restorations were fabricated using a standardized digital workflow and assessed over a 12-month follow-up period. The primary outcome was restoration survival rate, while secondary outcomes included technical complications, peri-implant biological parameters, marginal bone level changes, and patient-reported satisfaction.
This study aims to provide clinical evidence regarding the viability of 3D-printed definitive resin materials as an alternative to zirconia in implant prosthodontics.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Participants must meet all of the following:
* Age ≥18 years.
* Have one or two osseointegrated dental implants requiring prosthetic restoration.
* Demonstrate stable peri-implant tissues with no signs of inflammation or implant mobility.
* Maintain good oral hygiene and controlled periodontal status.
* Require either:
* A single implant-supported crown, or
* A short-span (maximum 3-unit) implant-supported fixed partial denture (FPD) supported by two implants in the mandibular anterior region.
Exclusion Criteria:
* Participants are excluded if they have any of the following:
* Severe parafunctional habits (e.g., bruxism).
* Uncontrolled systemic diseases affecting bone metabolism or healing.
* Peri-implantitis or compromised implant stability.
* Requirement for cantilever prostheses or long-span restorations, or FPDs in areas other than the mandibular anterior region.
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?

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?
