Quick Peek into NIOM Labs and the Three-Point Bending Test
Get a quick peek into our laboratories and a demonstration of a three-point bending test.
NIOM aims to ensure the safe and effective use of biomaterials. We work with all kinds of dental materials, including ceramics, alloys, and polymers. As a polymer chemist, Head of Laboratory, Hilde Molvig Kopperud, has a special interest in resin-based materials.
When investigating biomaterials, we try to mimic the clinical situation. However, as individuals, we are all different, and this can be quite difficult. Therefore, standardised methods are often used to achieve comparable and reliable results.
The three-point bending test is a standardised method present in many dental material standards to investigate the mechanical properties of a material by measuring the flexural strength. The test can be seen as simulating what might happen when external forces are applied to a material, for instance, during chewing.
As polymers, ceramics, and alloys have very different properties, the specifics of the test method are different for each type of material. However, the principles of the test are the same, using supports and a load to create flexure of the specimen, usually until fracture. This flexure will produce compressive forces around the point of impact and tensional forces on the opposite side of the specimen, causing the material to fracture.
Polymer materials are elastic or viscoelastic, and in the three-point bending test, we can see a deflection in the specimen that for some materials may be quite substantial. In some cases, the material will not fracture but just bend.
However, ceramics are brittle materials and will fracture after only a small deflection, but with a larger load exerted on them. The intended use of the material is reflected in the requirements given in the different standards. For instance, single-unit restorations will have a lower requirement for flexural strength compared to bridges with several units.

    There were many tests being done with fluoride in the 40s and 50s. I read that dogs were made very sick when fluoride gases were aimed at them. This film is propaganda to promote not having to spend many dollars on burying this toxic fluoride in the ground. There are many books on this subject like the one called: "The Case Against Fluoride" by Dr. Connett and Dr. Beck, etc. "When the U.S. Public Health Service endorsed water fluoridation in 1950, there was little evidence of its safety. Now, six decades later and after most countries have rejected the practice, more than 70 percent of Americans, as well as 200 million people worldwide, are drinking fluoridated water. The Center for Disease Control and the American Dental Association continue to promote it-and even mandatory statewide water fluoridation-despite increasing evidence that it is not only unnecessary, but potentially hazardous to human health. In this timely and important book, Dr. Paul Connett, Dr. James Beck, and Dr. H. Spedding Micklem take a new look at the science behind water fluoridation and argue that just because the dental and medical establishments endorse a public health measure doesn’t mean it’s safe. In the case of water fluoridation, the chemicals that go into the drinking water that more than 180 million people drink each day are not even pharmaceutical grade, but rather a hazardous waste product of the phosphate fertilizer industry. It is illegal to dump this waste into the sea or local surface water, and yet it is allowed in our drinking water. To make matters worse, this program receives no oversight from the Food and Drug Administration, and the Environmental Protection Agency takes no responsibility for the practice. And from an ethical standpoint, say the authors, water fluoridation is a bad medical practice: individuals are being forced to take medication without their informed consent, there is no control over the dose, and no monitoring of possible side effects." America is a fascist/nazi country proven by all the corporations that funded Hitler's war. All corporations are psychopathic according to the film "The Corporation". Corporations have taken over the world and is why america continues to bomb many other countries for their land and resources, like oil. Instead of building wind and solar parks, these corporations that don't care about us continue to frack the earth for oil and gas which sends huge amounts of gas into people's homes and land. We are all breathing it constantly. This is a huge story about the depopulation agenda. These corporations want 95% of the planet's people gone so they can take over. Just look up the depopulation agenda or agenda 21, etc. There is no oversight from the FDA or EPA because people like the Kochs buy them. I heard this in the DVD documentaries "GasLand 1 & 2" or "The Koch Brothers Exposed".
