8 G-ænial Bond Technical Manual
5.0 Features and benefits
adopting a dentist oriented approach, Gc formulated G-ænial Bond to offer ease of handling and
excellent clinical performance of the adhesive. the result is a bonding system providing the
following features:
• High performance in self-etch and selective etch approaches
• High bond strength to dentine
• Excellent marginal integrity
• Long-term, durable bond
• Reduced post-operative sensitivity
• Easy handling
6.0 composition
6.1 a unique formulation
the following table describes the various components contained in G-ænial Bond and their clinical
relevance.
table 3: composition of G-ænial Bond
component Function clinical relevance
4-met Functional monomer:
• Etching agent
• Wetting agent
• Promotes adhesion • Dissolves the smear layer
• Demineralises and creates space for monomer
infiltration
• Infiltrates the demineralised surface (micro-
mechanical adhesion)
• Initiates the interaction between the tooth
structure and the monomers (chemical adhesion)
Phosphoric acid
ester monomer
Dimethacrylate
monomers Resin monomer:
• Linking agent
• Networking agent • Links with the composite resin which is
hydrophobic
• Promotes cross-linking between the
dimethacrylate monomers
Distilled water • Promotes etching
• Solvent • Participates in the etching process
• Takes in the residues from the etching process in
order to remove them while being blown off
acetone Solvent • Evaporates water from the adhesive interface,
aiding long-term adhesion
Silicon dioxide • Adjusts the viscosity
• Reinforcing material • Eases the application of the bonding agent
• Strengthens the adhesive layer
Photo-initiator Photo-initiator • Polymerises the resin monomers upon light
energy activation
