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.
