In regard to bonding agents, the term “universal” is not regulated and can mean different things from product to product. The Dental Advisor has defined three criteria, and for a bonding agent to be considered “universal”, it has to satisfy at least two of them. Dental Advisor. May-June 2017 Vol. 34, No.3
Tokuyama Universal Bond meets all three criteria, making it a “true universal” without the use of extra products:
- Self-etch; compatible with total-etch and selective-etch techniques
- Compatible with all light-cure, dual-cure, and self-cure materials without use of activators
- Can be used as primer for silica-based, zirconia-based, and metallic restorations
Indications
Universal Use Comparison Table
- *1 Requires Dual Cure Activator (DCA) unless it is used with Rely X Ultimate
- *2 Bonding of dual-cured core build up composites to tooth structure as long as these materials are light-cured
- *3 Requires DCA
- *4 Requires Primer
- *5 Requires light-curing
- 6 Requires DCA and light-curing unless it is used with CLEARFIL DC CORE PLUS or PANAVIA SA CEMENT
- *7 Primer recommended
- *8 Only composite repair
Tokuyama Universal Bond offers high bond strength to polymerizable resin materials (resin cement, acrylic resin, and composite resin) and indirect restorative materials such as glass-ceramics (porcelain), oxide-ceramics (zirconia and alumina), metals (precious and non-precious), and resin materials including inorganic filler.

Mixing Ratios
The recommended mixing ratio for Tokuyama Universal Bond is 1:1 Bond A & B, but it maintains performance within a mixing ration of up to 1:3, leaving room for error:
Cavity Adaptation – Direct Restoration
Excellent cavity adaptation provides void-free bonding.

Self-cure chemistry provides reliable bond in deep preparations, as well as post and core build-ups that are difficult to reach with a curing light.
Active-Chemistry technology is superior to the conventional chemical polymerization initiator, a benzoyl peroxide/amine system because it exhibits high catalytic activity under strongly acidic conditions. A thin bonding layer forms after exposure to air, and hardens because of rapid progression of polymerization and curing on its adhesive interface (self-cure) once it comes into contact with resin materials such as composite.
