Evaluators’ Comments

  • “Wide range of applications. Can be used for virtually every situation – no etch required.”
  • “Good wettability.”
  • “I place engagers for Invisalign on porcelain crowns and I’m getting great retention.”
  • “No post-operative sensitivity.”
  • “I liked that it has a thinner film thickness than most two-step bonding agents.”
  • “Unidose containers have a flat bottom, so they are very stable.”
  • “Being a two-step process does take additional time.”
  • “The tabs on the unidose containers can be difficult to open – liquid can be lost.”
  • “Application includes a 20-second scrub time.”


  • Light-cured composite and compomer restorations
  • Porcelain, composite and metal-based inlays, onlays, crowns and bridges
  • Composite/ceramic/metal repairs
  • Cavity sealing for amalgam restorations
  • Light-cured or dual-cured core buildups
  • Cavity sealing as a pretreatment for indirect restorations
  • Veneers
  • Endodontic posts

Clinical Tips

  • For quadrant dentistry, there is enough to use in one unidose container.
  • Be careful when applying – it can be a bit ‘runny’ and irritate the surrounding gingiva.
  • Use a thicker microbrush with the primer to make sure it’s adequately covering the surface.
  • Make sure and blow air properly on adhesive until there is no movement.
  • My last bottle of bonding agent was contaminated, and I had tons of de-bonded composites. I like the unit doses so that I know my bond isn’t contaminated.



OptiBond eXTRa Universal is a two-component, light-cured adhesive that:

  • Reduces inventory with one single bonding protocol for all treatments and techniques through use of patented GPDM and Ternary Solvent System
  • Gives you the flexibility to choose your preferred etching technique without the need of any auxiliary products such as silane or dual cure activators
  • Uniform and very low film thickness delivers high aesthetic outcomes and also, provides a significant advantage for indirect restoration placement
  • Unique dark cure mode when combined with NX3 cement

Unique Attributes

  • Superior bond strengths
  • Can be used on any substrate as well as in place of silane and metal primers
  • Compatible with virtually all types of cements, composites and core-buildup materials without the need of auxilliary products
