Compared to other metals, nickel exhibits higher reactivity, increasing the likelihood of gum discoloration (black lines) and potentially causing mild toxic reactions.So, are cobalt-chromium alloy porcelain-fused-to-metal crowns harmful to the body?
Are cobalt-chromium alloy porcelain-fused-to-metal crowns harmful to the body?
Experts state: All metals possess some irritating properties. If we must rank their potential harm, cobalt-chromium crowns are more harmful than titanium alloys and many precious metals.While cobalt-chromium porcelain-fused-to-metal crowns are not the best option, they are affordable and pose minimal health risks. Patients need not worry excessively.
Characteristics of cobalt-chromium alloy porcelain-fused-to-metal crowns:
1. Strong corrosion resistance with high strength and hardness;
2. Excellent marginal seal to prevent external stimuli from damaging the dental pulp;
3. Economical and durable, offering high cost-effectiveness.
