As for the harm of cobalt chromium porcelain teeth, the common porcelain teeth, according to the relevant research report, nickel metal is more active than other metals, so the probability of gum black line is higher, and there is also a slight toxic reaction The cobalt chromium alloy is replaced by nickel metal by cobalt metal with stable properties. Compared with the metal with more stable properties, the probability of gum black line is much smaller.
In addition, although the cobalt chromium porcelain teeth are one of the common porcelain teeth, the cobalt chromium alloy porcelain teeth belong to the middle and upper class of the porcelain teeth, which can also be said to be semi precious metals Most of the causes of gingival discoloration are covered with nickel chromium alloy. Because some people are allergic to nickel, they will cause gingival discoloration; Another reason is that the inlaid porcelain teeth do not enter under the gum at the edge (the position where the edge of the denture contacts the gum), and there are food residues in the teeth over time, which corrodes the teeth and causes discoloration.
Therefore, the above symptoms are not due to the influence of cobalt chromium alloy porcelain teeth. In addition, the cobalt chrome porcelain fused to metal teeth are better in terms of adaptability to teeth, metal stability, and tooth adhesion, including light weight.
