With porcelain bonded crown, it is never possible to achieve such an aesthetic effect as in the case of all-ceramic or zirconium crowns. The metal is the main cause of that, as it does not transmit light and forms discolouration at the gum level. Additionally, metal can sometimes cause allergic reactions.

All-ceramic crowns not only provide beautiful and natural results, but are also durable and have no negative effects on the gums. Porcelain is attractive, strong, stable, and highly resistant to wear or stains. It offers a high level of biocompatibility because it does not contain metal.
