With the constant turmoil of cosmetic dental climaxes in the porcelain teeth and porcelain teeth into the line of sight of the U.S.
Porcelain teeth and porcelain teeth are as follows:
1. The gum does not change color: the metal of porcelain teeth crown after a long time within the oral cavity. Easily oxidized to form a gray oxide, bulk deposition to the gingival margin, causing the gums to be grayed out, affecting the appearance of all-ceramic dental totally does not happen.
2. Crystal clear: especially in bright light, it is impossible to achieve metal porcelain teeth, because the opaque metal porcelain teeth crown needed opaque porcelain covered metal substrate, affecting the transparency of the prosthesis, making porcelain teeth repair does not communicate through more metal base of the tooth neck caused by the "black line" appearance. The all-ceramic tooth with good transparency and refraction, high intensity within the crown to the neck of the tooth also can achieve good aesthetic effect.
3. Gingival health: nickel-chromium metal ceramic teeth, also known as the base metal porcelain teeth and stimulate gums more serious, some people its allergies, caused by gum swelling, bleeding, and even patients are also allergic to the precious metals. The all-ceramic tooth is basically found no sensitive cases.
4. Combination of inside and outside the crown: the combination of porcelain teeth metal crowns and porcelain teeth, porcelain crowns is the weak link, improper use or improper maintenance, the metal inside the porcelain teeth, porcelain crowns and porcelain teeth crown stripped, exposing the gray metal. The all-ceramic dental inside and outside the crown porcelain, ceramic and porcelain combined with closer, full porcelain teeth will not happen.
5. Will not cause wear and tear: the hardness of the porcelain crown is greater than the enamel, and can cause wear on the jaw teeth. All-ceramic hardness and dental supplies enamel approximate, not jaw teeth caused by wear and tear.
Based on the above, we know that in the repair of the effect of all-ceramic dental porcelain teeth compared to superior. In terms of price, the price of all-ceramic tooth is much more expensive than other porcelain teeth. So in the end the all-ceramic dental porcelain teeth, which still requires the patient to The role of the fixed partial denture abutments choose friends according to their own oral and economic conditions, only the best.
