The clinical indications for Tokuyama Universal Bond are:
- Direct anterior and posterior restorations with light-cure, dual-cure, and self-cure composite materials
- Intraoral repair of composite restorations, metal, porcelain fused to metal, and all ceramic restorations without an additional primer
- Cementation of indirect restorations and veneers when combined with light-cure, dual-cure, and self-curing resin cements
- Bonding and repair of denture resin to metal bases, clasps, or attachments
- Bonding of opaque resin to a metal base in the fabrication of resin-faced stainless-steel crowns
- Bonding of core build-ups using core build-up materials
A2. Tokuyama Universal Bond is self-etch; compatible with total-etch and selective-etch techniques.
A3. Tokuyama Universal Bond can bond the following surfaces: tooth (dentin and enamel), glass-ceramics (porcelain), oxide-ceramics (zirconia and alumina), metals (precious and non-precious) and resin materials including inorganic filler, without the need for an additional primer.
A4. Tokuyama Universal Bond is compatible to light-cure, self-cure and dual-cure dental materials without the need of a dual-cure activator.
A5. Yes, Tokuyama Universal requires storage under refrigeration (0-10°C/32-50°F). Tokuyama Dental recommends removing Tokuyama Universal Bond from the refrigerator 20 minutes before the first application. It may remain in room temperature throughout the day and needs to be returned to refrigeration after the last appointment/procedure of the day..
A6. Two years after the date of production under refrigeration (0-10ºC/32-50ºF). Tokuyama Universal Bond should be used by the expiration date indicated on the label of each container.
A7. TOKUYAMA UNIVERSAL BOND contains an alcohol and an acetone solvent, and they will evaporate from the bottle. This will accelerate the degradation of Tokuyama Universal Bond, and compromise the adhesive performance.
A8. Approximately 250 drops per one 5 mL bottle (A/B for each one).
A12. The pH level of Tokuyama Universal Bond after mixing is around 2.2.
A13. 5-10 microns.
A14. No, it does not.
A15. After dispensing Bond A and Bond B into the disposable mixing well (included in the Tokuyama Universal Bond Kit), complete the application within 3 minutes. When using a standard, more shallow mixing well, complete the application within 1 minute.
A16. Wipe the affected area immediately, and thoroughly flush with water after restoration. Affected areas may whiten due to protein coagulation, but the discoloration will disappear within 24 hours.
A17. Yes. Tokuyama Universal Bond releases fluoride upon placement, but not gradually.
A18. No, Tokuyama Universal Bond will not cause phase separation even if the solvent is evaporated because Tokuyama Universal Bond contains hydroxyethyl methacrylate (HEMA) which is relatively hydrophilic and improves the compatibility between water and monomer.
A19. Tokuyama Universal Bond virtually eliminates postoperative sensitivity because it contains hydroxyethyl methacrylate (HEMA), which penetrates into tooth substance and seals the dentin.
A20. No, this is not an indicated use for Tokuyama Universal Bond
