There are many kinds of braces because of different materials. Now some hospitals deliberately only report a few high ones, and the average porcelain (nickel-chromium alloy) hospital in Hangzhou is about 500. 1200 or so should be cobalt-chromium alloy, which can only be considered as medium.

The processing plants selected by general hospitals are also more formal. In fact, most of the porcelain in big hospitals is processed and made.
