NOVA COMPO-B PLUS BOND

Light-cure ethanol/water-based, self-etching, one-step, 7th Generation bonding agent.

Total-etch – Self-etch – Selective-etch mode for both direct and indirect restorations.

Two functional Monomers

4 META and MDP to form a better double chemical adhesion

The MDP monomer provides                                             

  • Strong and effective chemical interaction to tooth structure
  • Better adhesion performance
  • High Density of monomers – high amount of absorbed monomers to hydroxyapatite
  • Greater product stability
  • High adhesion strength for metal and non-glass ceramic substrates
  • Provides durability of adhesion; strong bond dentin to apatite surfaces by formation of non-soluble Calcium ions salts

BENEFITS

  • Mildly acidic too eliminate the postoperative sensitivity – sealing of dentinal Tubules
  • Indicated for light-cure composites, root surface treatment and cavity sealing.
  • Total Etch – Self Etch – Selective Etch
  • No mixing,
  • Highest bonding strengths to both dentin and enamel for seventh-generation,
  • Contains 2 functional monomers to form a better double chemical adhesion.
    • MDP monomer optimizes self-etch performance, increases shelf stability and provides durability of adhesion.
    • 4-META monomer enhances dentin bond strength.

 4-META – (4-Methacryloxyethyl trimellitate anhydride).

This component promotes the diffusion of monomers into tooth structure to form a hybrid layer

The 4-META adhesive resin impregnated the exposed collagen bundles with which it entangled to create the hybrid, essential to attaining high tensile bond strengths.

Indications:

  • Direct bonding of light–curing composite or compomer filling materials
  • Bonding of core build–ups made of
    • light–curing composite or
    • Duel – cure core build–up materials
  • Repair of composite or compomer fillings
  • Adhesive cementation of indirect restorations with light – and dual – curing luting composites
  • Sealing of prepared tooth surfaces before temporary / permanent cementation of indirect restorations
  • Root surface desensitization, dentine protector properties
  • Bonding of fissure sealants
  • Intraoral repair of composite restorations, porcelain fused to metal, and all–ceramic restorations without extra primer
  • Protective varnish for glass ionomer fillings
