Practical How To: The Science Behind the Bond: Futurabond U
On an experimental basis, we have asked a limited number of companies to provide us with practical “How To” answers to clinical questions. We were prompted to conduct this experiment when dental team members told us that they visit company websites and consult company representatives for practical clinical information. We look forward to receiving your feedback on this experiment.
In the video below, VOCO describes the science behind the dual cure universal adhesive, Futurabond U.
The bond itself contains an acidic monomer which has two different polarities in one molecule, a hydrophilic and hydrophobic component. The hydrophilic component bonds to the tooth while the hydrophobic component bonds to the composite. A hydrophobic cross-linking monomer is also added to the monomer and bonds to the hydrophobic composite material.
During application of the adhesive, the bonding agent’s acidic nature etches the enamel and then rises to a neutral pH during application. During the initial application to dentine, the acidic bond removes calcium exposing the tubules and underlying collagen fibers. The 3-D network is created which ultimately enables adhesion to the composite filling material.
Advantages of Futurabond U
- Formulation can be used in self-, selective- or total-etch and has dual cure capabilities so it can be used in light-, self- or dual-cure modes. In each use, maintains total-etch bond strengths above 30Mpa’s.
- Compatible with all restorative materials – does not require additional primer, activator or conditioner
- Even more indications including: desensitization, silane-like conditioning, protective varnish or sealant for GIC restorations
- SingleDose packaging eliminates solvent evaporation to maintain consistency of the chemistry delivered
- Thinner film thickness eliminates “halo” effect and reduces “pooling” effect during placement
- Nano-reinforced to help “wettability” and penetration into dentinal tubules
- No refrigeration required
