Bulk fill flowable
our new solution!

"Metafil Bulk Fill"restore with confidence and save time.
Metafil Bulk Fill is a resin-based light-cure, radiopaque and flowable restorative material for both direct andindirect restorations.
Its low polymerization shrinkage rate allows dentists to restore with a single layer placement up to 4 mm.
Metafil Bulk Fill minimizes the post operative complications and reduces chair time associated with treating
deep cavities.

The polymerization shrinkage of resin can pullbonded tooth structure toward resin side. Thiscan cause post operative discomfort and poor
adhesion between resin and tooth.

Bulk Fill method②①

To compensate this stress, incremental
placement technique was commonly deployed.
However often longer chair time has beennecessary to treat deep cavities.
Metafil Bulk Fill is the ideal for both clinicalconfidence and time-saving.

Direct restoration
Metafil Bulk Fill can be placed up to 4 mm increments including occlusal surface.
Veneering with composite resin can be used optionally when higher aesthetic is deserved.

Metafil Bulk Fill has achieved a low

*LPS stands for "Low Polymerization Shrinkage".
LPS monomer, newly developed by Mitsui Chemical Inc.,
provides a lower shrinkage rate than other monomers in the market.

Comparison of cavity adaptation
Metafil Bulk Fill would reduce thepolymerization shrinkage stress.
It will lead to better adaptation to thecavity.

The cavity (C-factor*=5) was bonded and bulk filled withMetafil Bulk Fill. Restored tooth was sectioned for observation.
No contraction gaps or enamel cracks were observed when
Metafil Bulk Fill containing LPS monomer was used.
In contrast, enamel cracks by polymerization shrinkage
stress were observed when a prototype flowable resin
without LPS monomer was used.

* The cavity configuration factor (C-Factor) isdefined as the ratio of the bonded to un-bonded
surface area. Higher shrinkage stress occurs withincreasing C-factor values. When the shrinkage
stress surpasses the bond strength, the risk ofcontraction gaps becomes higher. Likewise, therisk of enamel crack becomes higher when it
surpasses the strength of enamel.
