There are many advantages:
1. Compared with porcelain crowns, the number of molars with porcelain veneering technology is greatly reduced, generally less than 50%. Under the right circumstances, the amount of grinding teeth is even less.
2. Porcelain veneer technology is not easy to damage the pulp, and the sensitivity of the pulp of patients after tooth preparation is small. Compared with porcelain crown, pulp retention may be greatly increased.
3. Porcelain veneer technology has a high degree of aesthetics, which can achieve the effect of confusing the fake with the real for suitable cases.
4. In some cases, porcelain veneers can be prepared painlessly without anesthesia because of the small amount of molars. For most patients, the overall pain is less than that of porcelain crowns.
5. Porcelain veneer technology has little irritation to gums. If the edges are tightly sealed and polished, the gums can maintain good health.
6. Porcelain veneer technology has little damage to the adjacent relationship and occlusal relationship of teeth, and it is easy to recover after operation.
7. The design of porcelain veneer is the key, and the beauty of teeth and the design of porcelain veneer itself are very important. Such as: the design of edge, cutting end and occlusal surface position. Porcelain veneers can be changed according to different conditions of teeth, which requires doctors' sufficient experience and theoretical support.
8. The tooth preparation requirements of porcelain veneers are very high. Doctors should have enough experience in porcelain crowns before carrying out all-ceramic crowns and master all-ceramic crowns before carrying out porcelain veneer projects. Otherwise, it is easy to go wrong and should not be rash.
9. The accuracy of porcelain veneer is very important. Without an accurate model, there will be no accurate porcelain veneer, and there will be no good aesthetic effect and bonding effect.
10. The bonding of porcelain veneer is the key. Porcelain veneers have no retention and are bonded with adhesive. Any negligence in the bonding process may cause the veneer to fall off. However, if you carefully operate and cover the surface accurately, the bonding effect can be completely guaranteed.
Conclusion: Porcelain veneer technology will replace porcelain crown with its obvious advantages and become the mainstream technology of oral beauty in China.
Huamei oral cavity is very good.
