Often patients face the doctor’s introduction like falling in the clouds, many kinds of porcelain teeth, which one should I choose? Here, I give you an introduction to the types of porcelain teeth and their advantages and disadvantages, I hope to help you. Porcelain teeth called porcelain fused to metal crown, its basic structure is a layer of metal crown plus a layer of porcelain outside, according to the different materials of the metal crown, can be divided into nickel-chromium alloy porcelain, titanium alloy porcelain, cobalt-chromium alloy porcelain, precious metal porcelain, pure titanium porcelain. 1, nickel-chromium alloy porcelain inner crown for nickel-chromium alloy, due to some people are allergic to its allergies, tends to be eliminated edge. But its price is low, adapted to the Chinese national conditions. Long-term use of the neck edge of the black phenomenon will be more obvious. Nickel-chromium alloy is divided into beryllium-containing and beryllium-free two kinds, the former is harmful to the body, only small processing plant is still in use. 2, containing titanium alloy porcelain inner crown containing 4-6% titanium nickel-chromium alloy, due to the addition of titanium, the allergy rate is greatly reduced. The price is medium. 3, cobalt chromium alloy porcelain inner crown alloy is cobalt chromium alloy, remove the nickel element, biocompatibility greatly improved. In foreign countries as the lowest end of the porcelain application more. The price is medium. 4.Precious metal porcelain inner crown for the gold-platinum alloy or silver-palladium alloy, biocompatibility, soft porcelain color, long life, no neck edge of the black line phenomenon, the price is high. 5.Pure titanium porcelain inner crown of pure titanium, biocompatibility, light quality. The price is medium-high. Does not affect the magnetic resonance. In addition, the current application of all-ceramic teeth is becoming more and more widely used, there is a trend to replace the metal porcelain, all-ceramic teeth biocompatibility is the best, the color is the most realistic, the strength of all to meet the needs and even have the advantage of cast porcelain teeth, aluminum oxide all-ceramic teeth and zirconium oxide all-ceramic teeth, cosmetic aspects of the front teeth with irreplaceable advantages, the disadvantage is that the price is on the high side.
