Summary

This study aims to evaluate the clinical effectiveness of CAD/CAM 3D printed Chrome Cobalt fixed retainer in maintaining mandibular anterior teeth stability.

The Research Question; "Does the Cobalt-Chromium CAD/CAM designed customized lingual retainer better than Stainless steel lingual retainer in improving tooth stability after orthodontic treatment?" The null hypothesis "There is no differences between the fixed CAD/CAM 3D printed Chrome Cobalt customized retainer and the multi-stranded stainless-steel fixed retainer in maintaining mandibular anterior teeth stability."

Conditions

  • Tooth Stability
  • Periodontal Health
  • Patient Satisfaction

Interventions

DEVICE

Stainless steel fixed retainer

The Stainless steel fixed orthodontic retainer is fabricated from a 0.0215-inch, five-stranded stainless steel wire

DEVICE

3D printed CAD/CAM Chrome cobalt fixed lingual retainers

CAD/CAM Chrome cobalt retainers; will be digitally designed by the dental technician using EXOCAD software. Then, they will be printed by DMP Flex100 metal 3D printer and then will be polished. Also, a projection like extensions will be added at the ends of the retainers to avoid slippage in addition to gingivally directed V notch shaped bend in the retainer to increase the retention in the anterior region
