Gingiva ZR

Aesthetic ceramic coating applied over a baked resistant substructure based on ultra hard zircon and sodium oxide.

Gingiva imitates the gum when the corresponding tissue is lost in order to compensate for the loss and ensure an aesthetic appearance.

It is a mass of pink color, used to simulate a natural gum. This type of mass is mainly used in restorations, where it is necessary to recreate the gingival part on the crown.
