N2  - Introduction: Multi-stranded wires are superior to conventional wires in the fixed lingual retention after orthodontic treatment. The impact of the cross-section of those wires on its efficacy was not studied before. Aim: The aim of the study was to measure forces generated by multi-stranded lingual fixed retainers and comparing rectangular to round wires. Materials and Methods: A simulation model of the Orthodontic Measurement and Simulation System (OMSS) was used to measure the force generate in 15 rectangular and 15 round soft dead fixed lingual retainer wires on orthodontic stone models. The resistance was recorded after subjecting wires to gradual displacement in both load and unload directions, and horizontal and vertical axes
