Connexio®
Connexio dual-cure 7th-generation adhesive is the perfect complement to Encore D/C core material, providing dual curing deep in canal, right to the bottom of the post space for a completely polymerized, integrated tooth/core/post monobloc. 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 is designed for use with all types of composite resins – self-cure, light-cure, or dual-cure – and it tolerates residual moisture. It is the optimal bonding agent for dual cure composite materials, like Encore D/C.
- Dual-cured self-etch adhesive for direct and indirect restorations for all self-, light- and dual-cured resin materials
- Direct or indirect applications
- Nanoparticle reinforced
- Permanent, tight margins
- Equivalent adhesive properties to total-etch bonds
- Uses water as solvent (not acetone or ethyl alcohol); more tolerant of humidity than other adhesives.
- Greater rate of monomer conversion due to self-cure activation as part of dual cure material
- Enamel bond strength:
- 24.5 Mpa
(on unetched enamel; selective etching will increase enamel bond strength)
- Dentin bond strength:
- 39.3 Mpa
Note: We recommend selective etching of enamel for maximum bond strengths.

Can I etch before using Connexio?
Yes, you can.
How would you lute Maryland Bridges?
The enamel must either be roughened or conditioned with a phosphoric acid etching gel before applying Connexio.
How should I store 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.
How to Use this Product
- 1
- Prepare tooth. Remove excess moisture with a faint air jet. Do not over dry dentin.
- 2
- 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.
- 3
- Apply the adhesive in a layer of medium thickness to the enamel/dentin and rub into the tooth surface for 20 sec.
- 4
- Dry the adhesive layer for at least 5 sec with an air syringe.
- 5
- 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.
