Product Description
Clinically, GC Fuji II LC has shown 100% retention
after 5 years2 and has shown no evidence of secondary
caries or change in surface luster after 2
years.3 Its micromechanical reinforcement and triple
curing provide a chemical bond to tooth structure
with high compressive, tensile, and flexural strengths
for long-term retention and durability. It exhibits
translucency, expansion, and contraction similar to
tooth structure. In addition, GC Fuji II LC has been
proven to eliminate postoperative sensitivity. When
used as a base or liner in a sandwich technique,
restorations last longer because GC Fuji II LC prevents
marginal leakage and helps strengthen surrounding
tooth structure with superior fluoride
release. Additionally, GC Fuji II LC plays an integral
role in reducing patient discomfort via dentin-friendly,
self-adhesive bonding and functioning as a pulpprotective
thermal insulator.
Esthetics
GC Fuji II LC is available in 10 VITA shades
(A1, A2, A3, A3.5, A4, B2, B3, B4, C2, C4) for
quick and easy esthetic color matching. Its translucency
allows GC Fuji II LC to blend with natural
tooth color for lifelike results. After polishing, the
GC Fuji II LC restoration will resist staining and
discoloration for long-lasting esthetics.
One of GC Fuji II LC’s important attributes is
the ability to use it in moist fields in a variety of situations,
including Class III and Class V restorations.
It is ideal for cervical erosion/abfraction and root
surface restorations because its selfadhesive
chemical bond to tooth structure
allows it to work where isolation is
problematic. It features triple curing
(20-second light-cure; glass ionomer
and resin matrix self-cure) and can be
finished immediately.
Fluoride Protection
Unlike products with fluoride additives,
GC Fuji II LC offers clinically significant
fluoride protection with continual
fluoride release. Its rechargeable4
fluoride release and excellent marginal
seal help provide remineralization,
strengthening tooth structure. Research
has shown that high fluoride release
into the tooth helps prevent recurrent
decay,5 making GC Fuji II LC an ideal
choice for protecting pediatric and geriatric
patients with rampant caries and
multi-level treatment needs. GC Fuji II
LC bonds directly to tooth structure, so
fluoride release is undiminished by
bonding agents that can limit transfer
of fluoride into tooth structure.
Easy Technique
GC Fuji II LC can save chair time
because it requires fewer steps than compomers,
composites, and “pseudo” resinionomers
that require a resin bonding
agent to adhere to tooth structure. It
requires no dentin primer or bonding
agent, and its micromechanically reinforced
chemical bond prevents marginal
leakage. Neither undercuts nor mechanical
retention is necessary. Its consistency
contributes to ease of placement and
contouring and results in less “pull
back” than composite. While GC Fuji II
LC is perfect for Class III and Class V
restorations, particularly cervical erosion/
abfractions and root surface res -
torations,6 it is often used as a base or
liner in a sandwich technique. GC Fuji II
LC is clinically insoluble and bonds
extremely well to dentin, making it a
perfect sealant. GC Fuji II LC minimizes
the likelihood of microleakage and
washouts so that the margins stay intact,
maintaining the bond and sealing the
restoration.2
Restoration Steps
- Prepare the cavity and apply GC
Cavity Conditioner to remove the
smear layer and seal the dentin
tubules. (A 10-second application of
GC Cavity Conditioner will clean
the prepared tooth surface, promote
a better bond, and minimize the
chance of pulpal sensitivity.)
- Rinse and gently dry the cavity (do
not dessicate).
- Place the mixed GC Fuji II LC into
the cavity.
- Light cure, trim, and finish.
Simple Sandwich Technique
- Prepare cavity, apply GC Cavity
Conditioner for 10 seconds, and rinse.
- Place mixed GC Fuji II LC as a base
or liner, then light cure.
- Acid etch as needed, apply enamel
bonding agent, and finish the restoration
with a tooth-colored restorative.
Delivery Options
GC Fuji II LC offers 2 delivery
options—easy to mix, premeasured capsules,
or powder-liquid. GC Fuji II LC
capsules eliminate hand mixing. Just
triturate 10 seconds to the ideal viscosity,
place into the capsule applier, and
dispense directly into the preparation.
GC Fuji II LC CORE Material
GC Fuji II LC CORE Material powder-
liquid formulation is blue to easily
distinguish it from tooth structure during
placement. This material provides
light-cured core build-ups that bond to
metal pins and posts for increased
retention.—Allison Walker
