STRAIGHT ARCH THERMAL NITI WIRES, RECTANGULAR

Packages of 25 arches

The thermal niti arcs are inactive when the temperature cools below 20 ° and the thermal properties reach an optimal activation at 37 ° (body temperature). This unique feature allows an easy and simple bracket attachment in any malocclusion, and the potential use of longer sectional arches from the beginning of the treatment, to reach in this beginning quickly levels of alignment without trauma.

Many orthodontists provoke this martensitic phase by cooling the wire, below its transition temperature prior to placement, to simplify the coupling, particularly in moderate and severe malocclusions after hooking.

Since the thermal arc rises in temperature within the oral cavity, the transition from the martensitic to the austenitic phase causes the voltage to increase and the memory-form phenomenon to occur.

Because of the extreme flexibility and reduced strength characteristics of thermal niti, it is possible to hook arcs of larger diameters, thereby requiring less arc changes and an earlier transmission of bracket prescription information.
