Centrix® Connexio® Dual-Cure, Self Etch Bond
NEW 7th Generation Bonding System
Connexio® is a dual-cure, self-etching bonding system that creates a strong, resilient bond quickly and easily. Reinforced with nano-particles, Connexio® is indicated for use with direct dual- or self-cure composite restorations and core buildups including fillings, inlays, onlays, crowns, bridges and posts.
Connexio® is packaged with two parts: the self-etching dentin, enamel bonding agent and the dual-cure activator. It tolerates residual moisture and can be used with a variety of light-, self- and dual-curing composites.
Connexio® firmly bonds tooth to composite or resin cements for permanent, tight margins. Fast-acting and easy to apply, Connexio® reduces post-operative sensitivity – making it the perfect choice for both patient and doctor.
- Chemical-curing with additional activator for areas inaccessible with a light
- Adhesive core build-up
- Fixing of root pins/posts with dual-curing or self-curing composite cements
- Universal application
- Same adhesive properties as total-etch bonds

5-step guide to building a void-free, bonded composite post and core
STEP 1 Prepare tooth. Remove excess moisture with a faint air jet. Do not over-dry dentin.
STEP 2 Mix 1 drop of Liquid One and 1 drop of Liquid Two on a mixing palette with an application brush for approximately 2 seconds (produces a self-etching adhesive). Connexio Self-Etch Bond is dual-curing and therefore must be applied immediately after mixing.
STEP 3 Apply the adhesive in a layer of medium thickness to the enamel/dentin and rub into the tooth surface for 20 seconds.
STEP 4 Dry the adhesive layer for at least 5 seconds with an air syringe.
STEP 5 Polymerisation: A. Direct restoration - Light-, self- and dual-curing materials. The bonding layer must be polymerised with blue light (halogen or LED lights) for 10 seconds when using light-, self- and dual-curing restoratives. B. Indirect restoration - Light-curing luting composites: The bonding layer must be polymerised with blue light (halogen or LED lights) for 10 seconds 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 seconds with blue light (halogen or LED lights) as an optional step.
