Stainless steel archwires specifically designed for use with the Straight Archwire Technique. Use throughout entire treatment but best suited for mid to late stages of treatment. Special alloy within the archwire provides maximum spring while minimising fracturing. Pre-heat treated. Resilient: accepts severe bends with minimal fracturing and easily soldered. Etched midlines for arches: upper - 3 black marks, lower - 1 black mark. Australian Super Plus archwires feature high strength and spring-back with improved bending quality, ideal for high-force applications. Ortholoy-Blue, heat treatable archwires may be used 'as is', welded with low heat, or soldered. Best used when considerable bending is required because it will not fracture; excellent for use with edgewise arches, lingual arches, retainers and removable appliances.
