Product Description
Connexio 8th generation bonding agent provides the greatest flexibility and effective curing with all types of composite resins and is especially effective for post-Endo restorative treatment. Self-cure, light-cure, or dual cure! Connexio is the perfect complement to Encore D/C core buildup composite material, providing dual curing deep in the canal, to the bottom of the post space, for a completely polymerized, integrated tooth/core/post monobloc. Spot light-cure for immediate, easy core shaping; self-cure helps virtually eliminate polymerization shrinkage between material and dentin walls, preventing the micro-gaps where bacteria, fluids and ions can accumulate. The self-etching ability of Connexio provides strong dentin bonds without the need for a separate acid-etching step. And, Connexio is nanoparticle reinforced to provide bond strengths that last longer. Connexio tolerates residual moisture and is the optimal bonding agent for dual-cure composite materials, such as Encore D/C.
- Easy, fast mix (Part A + Part B) provides so many more clinical benefits: faster, more flexible, lowest polymerization shrinkage
- Self-etch adhesive eliminates the need for extra steps.
- For direct or indirect applications.
- Nanoparticle reinforced for strength and durability.
- Permanent, tight margins resulting from this specially designed multi-modality curing.
- Equivalent adhesive properties to enamel and dentin.
- Unique solvent (water + ethyl alcohol) results in bonding that is more tolerant to moisture and humidity than other adhesives.
- Greater rate of monomer conversion due to self-cure activation as part of dual-cure material.
Dentin bond strength: 39.3 Mpa
Enamel bond strength: 24.5 Mpa
Note: It is recommended to selective etch enamel for maximum bond strengths. Selective etching will increase enamel bond strength on unetched enamel.

How To's
- Prepare tooth. Remove excess moisture with a faint air jet. Do not over dry dentin.
- Mix 1 drop of Liquid 1 and 1 drop of Liquid 2 on a mixing palette with an application brush for approximately 2 sec (produces a self-etching adhesive). Connexio Self-Etch Bond is dual-curing and therefore must be applied immediately after mixing.
- Apply the adhesive in a layer of medium thickness to the enamel/dentin and rub into the tooth surface for 20 sec.
- Dry the adhesive layer for at least 5 sec with an air syringe.
- Polymerization —
- A. Direct restoration – Light-, self- and dual-curing materials. The bonding layer must be polymerized with blue light (halogen or LED lights) for 10 sec when using light-, self- and dual-curing restoratives.
- B. Indirect restoration – Light-curing luting composites: The bonding layer must be polymerized with blue light (halogen or LED lights) for 10 sec when using light-curing luting materials. Self- or dual-curing luting materials: When using dual- or self-curing luting materials, Connexio Self-Etch Bond also provides excellent adhesion without light-curing. Connexio Self-Etch Bond can also be light-cured for 10 sec with blue light (halogen or LED lights) as an optional step.
FAQs
Yes, you can.
The enamel must either be roughened or conditioned with a phosphoric acid etching gel before applying Connexio.
Tightly close Connexio Self-Etch Bond bottles after use. Store in an upright position to guarantee flowback of the liquid. Store at temperatures between 39°F – 73°F (4°C – 23°C). Allow Connexio Self-Etch Bond to reach room temperature before use. Do not expose Connexio Self-Etch Bond to direct sunlight or the chair light.
