Harm of porcelain fused to metal teeth

summary

I've made six porcelain teeth, few of them are good, and there are only three teeth left. Now let's briefly introduce the hazards of making conjoined porcelain teeth, so that patients and friends can have a better understanding.

Harm of porcelain fused to metal teeth

First, oral health is not easy to maintain and easy to infect. Not everyone is suitable for porcelain teeth. If the oral environment is not good (such as periodontitis, gingival bleeding, gingival swelling, etc.), it is easy to cause infection. In addition, when the teeth and crowns do not close well, it is also easy to cause secondary dental disease.

Second, the conjoined porcelain teeth are easy to cause secondary dental diseases. One is the uneven force on the conjoined porcelain teeth when chewing, which makes it easier for bacteria to loosen; the other is that when making porcelain teeth, doctors wear the teeth too much, which leads to the porcelain crown too close to the pulp, which is easy to induce infection. Therefore, porcelain teeth are still suitable for a single one to do.

Third: porcelain tooth materials cause allergy. Non precious metal porcelain fused to metal teeth are made of Ni Cr alloy with high temperature inside crown and outside crown. Because of its relatively low price, it is widely used in China. However, this kind of porcelain teeth has the following disadvantages: poor marginal fit; poor biocompatibility with human body; some patients will appear "black line" in the gingival tissue at the neck margin after wearing for a period of time. In foreign countries, there are even reports of allergic reactions caused by this kind of porcelain teeth. Furthermore, it is easy to appear the phenomenon of porcelain collapse in clinic.

matters needing attention

Special reminder: because the amount of tooth tissue removed is relatively large, and all ceramic teeth have a certain degree of transparency, if the color of the tooth itself is heavy, it will show the internal color after wearing, so the restoration of porcelain teeth is most suitable for vital teeth with large defects or residual roots and crowns restored with tooth color post core.
