The Sandwich Technique using glass ionomer plus composite resin offers significant clinical advantages.1

The Sandwich Technique may be open or closed. in the open technique, the Gi is used to replace the dentin and also fill the cervical part of the box, which results in a part of the Gi being exposed to the oral environment. Use the “open sandwich” technique when there is no remaining enamel at the gingival margin.

in the closed technique, the dentin is covered by the Gi, which is in turn completely covered by the overlaying composite. Use the “closed sandwich” technique when there is remaining enamel at the gingival margin.

Clinical benefits:yy Reduced post-operative sensitivityyy pulpal protection from irritation2 yy Fluoride release over time3 yy helps in prevention of demineralization4

yy Rapid placement and curing of a single bulk layeryy Aestheticsyy Radiopacity

Leading independent reviews confirm the benefits of the Sandwich Technique:yy placement of moisture tolerant glass ionomer restorative in subgingival interproximal boxesyy Reduced microleakage compared to composite-only techniques5 yy Zone of inhibition adjacent to the glass ionomer6

What is the Sandwich Technique? The sandwich of glass ionomer (Gi) cement, dental adhesive and composite resin is an effective technique that optimally combines the desirable properties of the restorative materials. in the sandwich technique, the Gi is placed as a liner or base, followed by placement of a resin composite to provide an aesthetic restoration of the remaining cavity.

“ When placing posterior composites, the key to preventing post-op sensitivity is to establish a gap-free resin/dentin interface, or use the Sandwich Technique.” – E. Hewlett, D.D.S.
