Comparison of 3D Printed Resin Fixed Mandibular Retainer Versus Conventional Fixed Bonded Retainer
Summary
NIH ClinicalTrials.gov registered study NCT07552155 on April 27, 2026, comparing 3D printed resin fixed mandibular retainers to conventional fixed bonded retainers. The clinical trial will evaluate bond pair conditions across both intervention types, addressing a noted gap in evidence regarding chair side time and bond failure rates for 3D printed fixed mandibular retainers. This trial registration adds to the growing body of orthodontic research on digital manufacturing applications in dental retention therapy.
“Although there are many studies in the literature concerning with methods of bonding of mandibular retainers whether directly or indirectly, there is a very limited evidence regarding their chair side time and bond failure. Also there are scarce data on 3D printed fixed mandibular retainers.”
About this source
ClinicalTrials.gov is the NIH-run registry of every clinical trial conducted in the United States, plus most international trials sponsored by US-based companies or institutions. By federal law, sponsors must register Phase 2 through Phase 4 studies before enrolling patients and post results within a year of completion. This feed tracks every new trial registration and study update, around 700 a month: drug interventions, device studies, behavioral protocols, observational research. Watch this if you scout drug candidates moving into mid or late-stage development, monitor competitor pipelines, or follow rare disease research where new trials signal patient hope. GovPing parses sponsor, phase, intervention, and target indication on each entry.
What changed
NIH ClinicalTrials.gov added registration NCT07552155, a randomized comparison of 3D printed resin fixed mandibular retainers against conventional fixed bonded retainers. The study lists Bond Pair as the condition and identifies two interventions: Resin fixed retainer and Conventional fixed retainer.
Orthodontic practices, dental research institutions, and manufacturers of 3D printed dental devices should note this trial as it may generate evidence on the clinical performance of additively manufactured retainers compared to traditional bonding methods. The trial addresses a specific evidence gap in chair-side time and bond failure rates for 3D printed fixed retainers.
