Liquid nitrogen is very cheap because it is a by-product of the production of liquid oxygen. Nitrogen is obtained from liquid air by distillation at -196Â°C. The gas obtained by this process is actually a mixture of nitrogen and about 1.25% noble (or inert) gases, argon, neon, krypton, and xenon.
Damon braces or any of the self-ligating bracketing systems are pretty standard now in orthodontic offices. It varies greatly by city or region, depending where you live, so anywhere between $4000 and $6000.
DamonÂ® braces use slide technology, allowing the orthodontist to slide the wire through special clips on the brackets and affix the position of the wire by closing the clips. This technology accelerates tooth movement by putting less stress on the teeth, allowing them to move more easily into their desired positions.
