1. Safety: less tooth tissue is abraded. The porcelain veneer has few tooth tissues removed. In some cases, it is not even necessary to remove the tooth tissues. In this way, a large amount of tooth tissues can be saved without killing nerves. The sequelae of full crown restoration such as pulp inflammation and necrosis after operation can be basically controlled, and the long-term health of natural teeth can be maintained.
2. Beautiful: good simulation effect. The cosmetic effect of the porcelain veneer simulation has the same optical characteristics as the natural tooth tissue, does not contain any metal components, and shows the best aesthetic effect. It will never appear the gingival black line phenomenon commonly seen in porcelain fused to metal teeth. When making porcelain veneer, there are a variety of porcelain blocks of different colors to choose from. At the same time, external dyeing can be used for fine color adjustment. In clinical bonding, there are a variety of adhesives with different shades of color and white masking agents that can be used to assist in adjusting the color of the porcelain veneer to achieve an overall and coordinated cosmetic effect. And the high wear resistance and non coloring of porcelain can make the porcelain veneer achieve permanent whitening effect.
3. Health: little irritation to gums. The porcelain veneer has excellent light transmission. When preparing the tooth, it can be flush with the gingiva, which is conducive to protecting the gingiva, making impressions and bonding porcelain pieces. The area connecting with the gingiva is also only on the labial side, which has less irritation to the gingiva. There will be no gingival discoloration caused by metal ions of metal porcelain teeth. The hardness of porcelain fused to metal crown is higher than that of enamel, which can cause the abrasion of jaw teeth. The hardness of porcelain veneer is lower than that of enamel, which can effectively protect the opposite teeth.
