Orthodontic bands are stainless steel braces used to wrap or anchor an arch wire to the teeth. Dental defects like unaligned teeth, protruding jaw, or buck teeth. Used to improve the overall dental health of a patient. Along with the other basic elements that should be used (e.g. arch wire, bonding material, and ligature elastic), braces help the teeth undergo a process called bone remodeling, or making the teeth stronger during loaded activity, such as eating. http://www.yameiortho.com/orthodontic-band/
