Strength and Versatility for Indirect Restorations

Alex Vasserman, DMD, on BISCO’s Duo-Link Universal™

There are many cements on the market today, so as a clinician, how do you decide which one to select from your armamentarium? The first step is to determine whether the restoration in question should be adhesively bonded, as in the case of an onlay, or if it should be conventionally cemented using a traditional cement, such as zinc phosphate. The advantage of conventional cementation is that it's a faster procedure that requires fewer steps. Bonding requires additional steps; however, it results in a stronger restoration because the cement chemically bonds to the restoration and to the tooth. In cases with poor mechanical retention, such as those involving a short clinical crown or an overtapered preparation, a bonding protocol is preferred because it achieves far greater retention than conventional cementation. For those cases in which high bond strength is required, an adhesive resin cement provides an optimal solution.

BISCO's Duo-Link Universal is a dual-cure adhesive resin cement that's reliable, strong, and competitively priced. It is designed to bond a variety of indirect restorations and materials, including lithium disilicate, zirconia, metal, fiber posts, Maryland bridges, and feldspathic porcelain. Duo-Link Universal works equally well with both pressed and CAD/CAM lithium disilicate. Due to its high degree of conversion, it has a low solubility, a high mechanical quality, and strong adhesive properties. For placing veneers, a light-cure veneer cement such as BISCO's Choice 2 is recommended.

Duo-Link Universal's auto-mix dual-syringe makes dispensing the cement quick and simple, and the material comes in two shades: Universal and Milky White. The Milky White shade is more opaque than the Universal shade and can be used to mask darker tooth preparations or raise the color value of a restoration. Both the Universal and the Milky White shades have a low film thickness, which ensures the complete seating of a restoration while effectively sealing the margins. Once Duo-Link Universal has been quickly tack cured, removing the excess cement is simple and predictable. In addition, it is highly radiopaque, making future radiographic identification and diagnosis effortless.

A dual-cure adhesive resin cement is an excellent choice for cases that require high bond strength and optimal retention. When a strong, cost-effective, easy-to-use, radiopaque cement that's easy to clean up is desired for the cementation of indirect restorations, BISCO's Duo-Link Universal adhesive resin cement should be in every clinician's armamentarium.
