Comparison of 3D Printed Metal Fixed Retainer Versus Conventional Fixed Bonded Retainer

Sponsor: Amany Ibrahim

View on ClinicalTrials.gov

Summary

Despite the growing diversity of materials used for mandibular fixed retainers, the evidence base remains inconclusive. In particular, conflicting findings have been reported regarding the bond failure of titanium retainers across different evaluation periods, including immediate and 12-month outcomes. Additionally, the emergence of 3D metal-printed retainers has not yet been matched by sufficient clinical evidence, with current data being limited and lacking long-term validation.

Interventions

DEVICE

bar 3d printed metal fixed retainer

Participants will receive a custom-designed 3D-printed metal fixed retainer. The retainer is digitally designed using intraoral scans and fabricated using metal 3D printing technology to achieve a precise fit tailored to each patient.

DEVICE

conventional fixed retainer

Participants will receive a conventional fixed bonded lingual retainer (canine-to-canine) fabricated using multistranded stainless steel wire and bonded using standard clinical procedures.
