Cobalt chromium braces are divided into ordinary cobalt chromium braces and bio-laser cobalt chromium braces. The cost of ordinary cobalt chromium braces is usually around 700-900 yuan, and laser cobalt chromium braces are around 1200-1500 yuan, and the price standard may be different depending on the province. Cobalt chromium braces also have a layer of porcelain on the surface, and the aesthetics are quite good. However, if used for the restoration of front teeth, the color is not so aesthetically pleasing under the effect of translucent light. Cobalt chromium braces are likely to release metal ions if they are in the mouth for a long time, causing the gums to stain and darken. If the patient needs to do head MRI later, metal-containing braces may produce artifacts that affect the diagnosis of medical treatment, so it is recommended that patients choose to undergo all-ceramic restoration when available.
