Top benefits of OptiBond eXTRa Universal


Strong & durable

OptiBond eXTRa Universal ensures a double effective action on both tooth structure and the restorative material, resulting in effective bond strength and durability.


Consistent & simple

Rely on one single protocol for all indications: from direct to indirect in combination with any type of resin.



The patented OptiBond technology delivers excellent penetration into dentinal tubules, giving you protection against microleakage and post-operative sensitivity.



Reduce inventory with the choice of one single bonding solution for all treatments and techniques.



Uniform and very low film thickness delivers amazing aesthetic results.

The science


The Gold Standard in Adhesion

The proven OptiBond™ GPDM Monomer ensures better adhesion with both the tooth structure and the resin material and overall higher bond strength.

  • An acidic phosphate group effectively anchors the adhesive to the hydrophilic surface of the tooth.
  • The presence of more methacrylate functional groups, compared to other adhesive monomers such as MDP, allows a more effective interface with the hydrophobic resin.


Effective Plug & Seal Action

The primer component is very acidic and hydrophilic, resulting in unique nanoetching capability and outstanding dentin tubule penetration. The Adhesive component is hydrophobic, offering efficient polymerization to boost mechanical strength, bond durability and marginal integrity.
