Proof that glass ionomer restorations
greatly exceed expectations
In 1995, this patient required replacement of a Class II
composite restoration. After checking the occlusion and
load-bearing factors, the operator decided to apply the
world’s first high-strength glass ionomer material for pos-

Lamination strengthening
- achieving optimum maturation.
G-Coat PLUS is a tough, nanofilled, self-adhesive coating
that chemically bonds to Fuji IX GP and surrounding tooth
surfaces. When applied to glass ionomer cements, this
means that G-Coat PLUS hardens the lamination, markedly
increasing the fracture restoration toughness as well as resist-
ance to early wear and acid.
Glass ionomer restoration gather strength in two ways:
internally and externally. Internally, the chemical reactions
mature and strengthen the cement, and externally, the
uptake of calcium and phosphate from saliva strengthens
the cement’s surface. Based on our R&D findings, you’ll
achieve the greatest improvement by coating glass ion-
omer restoration with a protective layer. This allows the
core of the restoration to mature and then over time allow
delayed exposure to saliva to start the surface hardening
process through uptake of calcium and phosphate. If this
is what you need to do, you’ll find no better coating mate-
rial than G-Coat PLUS.
