They are made of a nickel-titanium alloy with a rectangular cross-section and a dimension of .018 inches.
Spee-Arches are designed to help correct a common issue known as deep bite or overbite, where the upper front teeth overlap significantly with the lower front teeth. The Spee-Arch design features an upward curve, which helps to level the curve of Spee, a natural curve that occurs in the lower arch of the mouth. By leveling the curve of Spee, the lower arch can better support the upper arch, leading to a more balanced bite.
The .018 Lower Titanol Spee-Arches are typically used in the lower arch of the mouth and are compatible with many different bracket systems. They are sold in packs of 10 and should only be used by trained orthodontic professionals.
