1. There is no black line on the edge of the gums, no sense of thickness, no swelling and bleeding of the gums, so that you really feel that porcelain teeth grow from your own gums.

2. The light transmittance matched with the real teeth no longer has the embarrassment of "green teeth glittering" under the light.

3. The compressive strength is comparable to that of porcelain fused to metal teeth, and there is no need to worry about porcelain cracking.

4. No harmful metal ions will seep out and affect your health.

5. The number of molars is less, and the tooth tissue is retained to a greater extent.
