Researchers as the KTH Royal Institute of Technology in Stockholm say that new material, inspired by dental reconstruction methods, is stronger than dental filler itself. The patch should also help address the problem of setting an adhesive within the human body's moist environment.

Specifically, the research team reports that the new bone adhesive, which mixes the stiff, load-bearing aspects of dental resin composites with the adhesive power of self-etching primer, was successfully used on rats.

The method of curing the material is the same one used by dentists who employ a violet light when finishing a tooth repair. This technique hardens the composite material. The technical name for the chemical process is thiol–ene coupling (TEC), which guarantees a bonding response when water is present.

In fact, says Michael Malkoch, Professor of Fiber and Polymer Technology at KTH, use of the pioneering adhesive patch results in bonding power 55 percent greater than commercial dental bonding adhesive -- which makes the material a valuable alternative to plates and screws.
