Lucid-Lok® Archwires are Short Term Ortho specific wires that provide the highest memory, lowest force and maximum corrective potential. They also help minimise the need for interproximal reduction because of the unique and broad archform. The colour of Lucid-Lok® wires blends well with the patient's tooth structure. Rectangular wires are used in some specific situations and are not included in the Patient Tray Kit.
