刚看了下，
发现有porcelain/metal 和 ceramic 两种材料可以选。
这个ceramic就是全瓷的吧？
因为我是最后一颗磨牙，所以打算用第1种。
有2问题：
1. porcelain/metal就是金属/烤瓷？这个metal的种类可以选择么？比如贵金属，或者
不含Ni什么的？通常用怎样的金属好？
2. 是不是porcelain/metal比ceramic要坚固？如果金属种类不能选，只有镍钴之类的
，那会不会对健康不好？这样情况下是不是应该选ceramic?
谢谢啦！ | t*******n

the exact ingredient but sometimes have a color option (all-metal crowns can
come in golden or silvery). Nickel/chromium is generally not offered in
the US. Double check with the dentist though.
Ceramic crowns are natural-looking than porcelain/metal, but are less strong
. Since your crown is for the 2nd molar, which is a major chewing tooth and
not very visible from the outside, you are better off with the porcelain/ | x******i
