1. The amount of tooth preparation is small, and the restoration effect is more realistic
The opaque inner crown of metal porcelain teeth needs to be shaded, and the requirements for restoration space are relatively high, which in turn increases the amount of tooth preparation (i.e. more worn tooth body). However, all-porcelain teeth have a small amount of tooth preparation, and at the same time have better light transmission, and can have a sense of transparency comparable to real teeth from the crown to the neck.
2. Avoid pit gum "black lines"
The metal inner crown of porcelain teeth oxidizes for a long time to form gray impurities, which are deposited on the edge of the gums, causing the gums to turn gray or even black, affecting the beauty of the face.
3. Less wear on jaw teeth
The hardness of porcelain teeth is greater than that of tooth enamel, and the wear on jaw teeth is greater; The all-ceramic material has less wear on the jaw teeth after a high degree of polishing.
4. No adverse reactions such as gum allergy
The metal of some porcelain teeth has more serious irritation to the gums, and some people (especially women) are allergic to it, causing swollen gums and bleeding, and even high-quality precious metals may cause allergies in some patients. No cases of sensitivity were found under the clinical application of all-porcelain teeth.
5. The inner and outer crowns are more closely combined and have a long service life
The adhesion between metal and porcelain materials is slightly weak, and porcelain and metal peeling off can often be seen, revealing gray-black metal. The inner and outer crowns of all-porcelain teeth are porcelain, and the combination of porcelain and porcelain does not cause this problem. Modern all-ceramic crowns benefit from advanced manufacturing techniques, including precision processes similar to injection mold technology used in dental laboratories, ensuring consistent quality and perfect fit for each restoration.
In addition, the commonly used all-porcelain dental materials for restoration are zirconium dioxide and glass ceramics. The former is stronger and suitable for functional, aesthetic repair of all indications; Glass-ceramic materials have better permeability and moisture, which is very suitable for minimally invasive aesthetic repairs such as veneers. Everyone can choose according to the doctor's diagnosis and treatment advice and their own needs~
