As you may know, dental porcelain veneers are a more traditional way to repair teeth, but not everyone has heard of all porcelain crowns. There are both connections and differences between them. What are the differences between porcelain veneers and Full porcelain crowns?
In fact, both porcelain veneers and all porcelain crowns belong to the category of fixed restoration. Many people may mistakenly think that full porcelain crowns are veneers, there is no difference between them. But in fact, this is not the case, it can be seen from the price of both.
The appearance of all ceramic teeth is transparent and more like real teeth, which is a difficult task for porcelain veneers. Because the internal metal crown of porcelain teeth is opaque, opaque porcelain is needed to cover the metal base, which affects the transparency of the restoration, so that the porcelain teeth have obvious chalky color, pale, false, and the “black line” caused by the metal base in the neck of teeth affects the beauty.
all porcelain crowns have good transparency, refraction and high strength of the internal crown to solve this beauty problem, so that the teeth neck can also achieve good aesthetic effect.
The reason why all porcelain crowns are more expensive than porcelain veneers lies in the aspect of crowns. The combination of metal and porcelain is a weak link. It is often seen that porcelain and metal peel off, exposing the gray black metal. all porcelain crowns are porcelain, the combination of porcelain and porcelain will not appear this situation.
In the way of making, the difference between porcelain veneers and all porcelain crowns is also obvious. According to Global Dental Lab, in the process of making ordinary porcelain veneers, first of all, a metal base should be cast, and then the metal surface should be decorated with porcelain to simulate the shape and color of natural teeth. Because of the existence of metal base, opaque materials must be used to cover the metal, so that the light scattering of the porcelain teeth is different from that of the real teeth. When the strong light is direct, the porcelain teeth will lose their natural color, showing the white color of the false teeth. If the metal base layer is removed, the strength of the porcelain teeth will be greatly reduced, and it is easy to break, so the effect of ordinary porcelain teeth is still inadequate.
So how are all porcelain crowns made? all porcelain crowns refers to making an internal crown on the treated root. The internal crown is a transparent supporting framework of all ceramic, and then baking a layer of porcelain powder similar to the color of natural teeth on its external crown surface, and finally bonding on the teeth. It is a high-tech dental inlay method developed in recent years.
In addition, there are other differences between porcelain veneers and all porcelain crowns. Porcelain veneers dental equipment is relatively simple and low cost. The production of all porcelain crowns requires special equipment, which is time-consuming and expensive. The operators need special training. all porcelain crowns are biocompatible, insoluble in saliva and other acidic and alkaline substances, and will not cause allergic reactions. Because of the presence of metal base crown, there are cases of metal allergy and the occurrence of metal microleakage.
We certainly know something about porcelain teeth and all porcelain crowns, but we don’t know so much about them, so we will face some difficulties when we choose them. However, as long as we know more about them, there should be no big problem.
