Riva Bond LC
- “Easy to use, multipurpose product.”
- “Coats tooth surface well.”
- “I’m interested to see if the ‘compensation’ aspect of the polymerization results in less evidence of marginal leakage over time.”
- “Good radiopacity.”
Riva Bond LC is a light-cured bonding agent based on resin-modified glass ionomer chemistry. It is designed to expand enough to compensate for polymerization shrinkage, while maintaining adequate bond strength. It is indicated for use as an adhesive for direct restorations, for bonding composite resin to self-cured/light-cured glass ionomer cement in the sandwich technique, bonding between layers of composite resin in larger restorations to reduce polymerization shrinkage stress, sealing hypersensitive cervical areas, and as a liner under amalgam fillings. Preparations should be etched with 37% phosphoric acid for 5 seconds, rinsed thoroughly and dried but not desiccated. Riva Bond LC comes in capsules that must be activated by depressing the plunger and triturated for 10 seconds in an amalgamator prior to adhesive placement. Use the provided brush applicator to pierce the foil end of the capsule and apply a thin layer of Riva Bond LC to all surfaces (air thin if necessary), and light cure for 10 seconds. Riva Bond LC was evaluated by 29 consultants in 590 uses. This bonding agent received an 86% clinical rating.
The unique delivery system of Riva Bond LC provides fresh adhesive for each use. Capsules are easy to activate and mix, although consultants noted that having to use an amalgamator was inconvenient. The four-minute working time and the volume of liquid in each capsule are ideal for use on multiple teeth. Seventy-nine percent of consultants were using a self-etch adhesive; 80% of those would be willing to switch for increased durability of the bond. Riva Bond LC coats the tooth well and can be thinned with air before light curing. Bond strength to dentin is 14MPa.
