Orthodontic Treatment for Molar Uprighting - Cantilever Spring Correct fabrication and adjustment of the 'T' spring will achieve satisfactory results in the required tooth movement. The spring cantilever bridge replaces a single upper tooth that is lost. When tied to the braided ligature strands, the stored energy in the spring generated optimum eruptive force in the occlusal direction. • Used for mesio-distal movement of teeth and can be used in teeth that are placed correctly in buccolingual direction. When tied to the braided ligature strands, the stored energy in the spring generated optimum eruptive force in the occlusal direction. Although few adults would ever need one there is however, a use in pediatric dentistry. Also known as flat springs or spring clips, cantilever springs can be manufactured to many different sizes and shapes and are used in many different products. Several orthodontic approaches are suggested for mandibular molar uprighting, such as Australian uprighting spring, cantilever spring, prefabricated Sander spring, helical uprighting spring, NiTi coil spring, push spring appliance, and traction from removable appliances are few of the currently available options [6, 8, 9].
