Editors' Comments
- “Excellent viscosity - wets the tooth surface well.”
- “The illustrated instruction card is a good quick reference for chairside use.”
- “The instructions clearly explain the use and storage requirements.”
- “The design of the unit dose is great.”
- “The material does not stick to matrix bands.”
- “The need for refrigeration makes storage and use a bit more time consuming.”
Description
BOND FORCE is a single-component (7th-generation), self-etching,
fluoride-releasing bonding agent. It requires one application and a light curing
time of 10 seconds. BOND FORCE contains Bis-GMA, HEMA, phosphoric acid monomers,
and an alcohol solvent. It is supplied in a 5-ml bottle and 20 or 50, 0.1-ml
unit-dose capsules. The adhesive needs to be stored at a temperature of 32° to
55° F and should not be used with self-cured composites. It is indicated for
bonding of light- or dual-cured materials to cut/uncut enamel and dentin and for
composite repair of fractured ceramic. Twelve editors evaluated BOND FORCE in
186 clinical applications. This product received a 96% clinical rating.

Editors' Observations
Manufacturer’s Instructions
The instructions clearly describe the need to use the material within five
minutes of dispensing. Requirements for rubbing the material along the
demarcation line and uncut enamel for 20 seconds followed by five seconds of
indirect air drying and five seconds of direct air flow are also clearly
described. The editors would prefer a product that does not require
refrigeration.
Packaging/Kit Contents
Editors appreciated the simple packaging with a 5-oz, soft plastic bottle.
The unit-dose packaging is easy to use. The unit-dose is easily converted into
an upright, stand-alone container to prevent material from leaking out during
the procedure.
Ease of Dispensing
The soft plastic bottle is easy to squeeze and dispenses single drops that
are relatively uniform in size.
Viscosity/Ease of Application
The viscosity of the material is very good. The material is easy to control
as it is dispensed and thoroughly coats the tip of the brush. When applied to
the tooth, the material coats the surface without pooling or excessively flowing
out of the preparation.
Convenience of Unit-Dose
Editors found the upright stand-alone design of the unit dose to be unique
and useful. The use of a unit-dose or bottle system is a personal choice of each
clinician and the availability of both is important.
Ease of Air Dispersal
The viscosity of the material allows it to be easily dispersed with air,
without excessive flow out of the preparation. The highly specific technique for
air dispersal is an additional step and instructions that the editors felt could
be simplified.
Time Required for Bonding Procedure
The ease of dispensing, controlled viscosity and good coverage make the
material easy to apply. The editors found the required 20-second rubbing and
10-second air application times to be acceptable for a 7th-generation bonding
material.
Absence of Stain at Cavosurface margin
No stain was reported by the editors during the two-month evaluation
period.
Ease of Band Removal
Unlike some other 7th-generation bonding systems, BOND FORCE does not adhere
to the surface of the metal matrix band and therefore makes band removal very
easy.
Odor/Taste
While the odor of the solvent was apparent, it was not noted as objectionable
by the editors or patients.
Postoperative Sensitivity
No post-operative sensitivity was reported during the two-month evaluation
period.
Usefulness for Various Restorative Procedures
Over 230 direct Class I-V composite restorations were placed using BOND
FORCE. Some editors suggested a dual-cured component would allow them to expand
the use of this material.
Editors' Note: Tokuyama Dental Corp./Tokuyama America, Inc. recently modified the instructions for BOND FORCE.
- Apply bonding agent and rub for 20 seconds
- Weak air dry for 5 seconds
- Strong air dry for 5+ seconds
- Light cure for 10 seconds
