Tooth Hardness Evaluation Using Nanoindentation
In this application, the Nanovea Mechanical Tester, in Nanoindentation mode, is used to study the hardness and elastic modulus of the dentin, decay and pulp of a tooth. The most critical aspect with Nanoidentation testing is securing the sample, here we took a sliced tooth and epoxy mounted leaving all three area of interest exposed for testing.
3 Point Bend Test Using Microindentation
In this application, the Nanovea Mechanical Tester, in Microindentation mode, is used to measure the flexural strength (using 3 Point Bend) of various sized rod samples (pasta) to show a range of data. 2 different diameters were chosen to demonstrate both elastic and brittle characteristics. Using a flat tip indenter to apply a point load, we determine stiffness (Young’s Modulus) and identify the critical loads at which the sample will fracture.
Micro Scratch Depth Measurement Using 3D Profilometry
In this application the Nanovea ST400 Profilometer is used for depth measurement of a row of micro scratches created using Nanovea’s Mechanical Tester in scratch mode. In seconds the Profilometer, with a single line pass in 2D mode, provides area and depth measurement.
