Oral Wear Simulator
This is the leading oral wear simulator which research has found to produce and simulate realistic measurements of the two major wear mechanisms, abrasion and attrition on each specimen. A ball-on-plane arrangement transmits a low force during sliding of 20N, followed by a 90N pulse at the end of the pass to produce a revolutionary slide-and-clench action. The two-phase wear pattern is then measured. Developed at OHSU, results from numerous round robin studies have found a strong correlation to occlusal-contact and contact-free measurements from in vivo studies. The system has been used by numerous institutes and manufacturers to characterize wear of composites, adhesives, ceramics, amalgams, and natural dentition.
