OptiBond™ eXTRa Universal Bottle Refill Primer

Two-component universal adhesive
Introducing OptiBond™ eXTRa Universal, the bonding agent from KaVo Kerr with unique Smart pH technology and patented formula enriched with GPDM monomer and the Ternary Solvent System.
• Outstanding compatibility with virtually all types of cements, composites and core build-up materials, eliminating the need for auxiliary product
• Easy and consistent two-bottle protocol with any etching technique
• Full reliability afforded by OptiBond technology, known as the “Gold Standard” in adhesion

Bond strength to enamel and dentine

OptiBond™ eXTRa Universal yields outstanding results ensuring superior bond strength compared to leading competitors on both dentine and enamel. This offers a consistent outcome under different etching techniques and substrates.

Imperceptible film thickness

The unique formula has a very low filler load (only 15%), producing a film so thin it is not visible to the naked eye. The result is highly aesthetic without, however, compromising strength.

Effective plug and seal action

The Primer component is very acidic and hydrophilic, resulting in unique nano-etching capability and outstanding dentinal tubule penetration. The Adhesive component is hydrophobic, offering efficient polymerisation to boost mechanical strength, bond durability and marginal integrity.

High shear bond strength and full compatibility

The combination of OptiBond™ eXTRa Universal and NX3 universal adhesive cement proved to deliver superior bond strength to dentine without the need for auxiliary products, compared to leading competitors. So you can experience predictable outcomes with the simplicity of a consistent protocol.
