Summary

The aim of this study was to compare the differences in relapse and failure rates in patients treated with fixed retainers (FRs) using Computer-Aided Design/Computer-Aided Manufacturing technology, lab-based technique, and chairside method.

Conditions

  • Relapse

Interventions

OTHER

Computer Aided Design/ Computer Aided Manufacturing Retainers

Custom-bent fixed retainer wires from an in-office CAD/CAM system with FixR software and the BenderI machine (YOAT Corporation, Lynwood, WA). Dentaflex wires- round, 0.5mm in diameter, three-stranded Stainless Steel (Dentaurum GmbH \& Co., Ispringen, Germany)- were used for the CAD/CAM group

OTHER

Lab-based Retainers

The lab group used the same type of wire as the CAD/CAM group but was manually bent by a lab technician

OTHER

Chairside Retainers

The chairside group used three-stranded Stainless Steel, 0.974mm x 0.402 mm, flexible Ortho-FlexTech wires (Reliance, Itasca, IL)
