Which is better, glass ion or polycarboxylic acid?

1, Transparency: Glass ions ensure a higher level of transparency due to their superior optical properties, making the display of patterns or characters clearer. Compared with polycarboxylic acids, the transparency of the latter is relatively low.

2. Durability: The special structure on the surface of glass ionomer cement crown ensures longer durability. Its anti-fading and anti-damage characteristics make it remain in good condition after long-term use, while polycarboxylic acid will fade or be damaged to some extent after a period of time.
