John Condon, M.S. Biomedical Engineering The pioneering research on the intra-oral wear of dental filling materials led to a consensus view that the degradation of restoratives took place mainly through two mechanisms. However, the need to reproduce these mechanisms in an in vitro simulator remained a challenge. Three body wear causes the generalized loss of material in contact free areas through the mild abrasive action of the food bolus....

Researching the fatigue resistance of restorative materials and structures is a mainstay of dental research, but the equipment available has traditionally been cumbersome or expensive. Mechanical testing machines as subject to wear, hydraulically-driven instruments are expensive and devices that use static weights are inaccurate. Consistent loading is essential for a phenomenon already plagued by uncertainty, the way fatigue is. These challenges were addressed in Proto-tech's precision-solenoid driven platform, which provides four stations of loading in an computer-controlled device....

After 25 years as an industry leader, Proto-tech's Oral Wear Simulator received several upgrades that will ensure its place in the pantheon of dental materials research tools. Simultaneous thermal cycling was the request from a Southeast Asian University, and Proto-tech accepted the challenge. First the chambers were modified so that a stream of alternating hot or cold fluid flowed downward, over the specimens and out through a port in the base....
