A new step in the development of dental treatment materials
The nanocomposite material that researchers from Beihang University, Peking University and the University of Michigan developed is similar to biomimetic enamel with essential multi-layered structures.
Scientists from Chinese and American research institutes have developed a material similar to artificial enamel, which is expected to be a promising candidate as a dental treatment material thanks to its mechanical strength. , superior hardness.
Enamel is the thin layer of acellular tissue that covers the outside of the tooth. This crust is the hardest tissue in the human body, but can crack, chip, and be dissolved by acids. This is the reason leading to many common oral problems such as tooth decay, tooth wear, fluorosis. To have strong teeth, the enamel layer must be protected permanently.
The nanocomposite material that researchers from Beihang University, Peking University and the University of Michigan developed is similar to biomimetic enamel with essential multi-layered structures.
According to a research paper published in the journal Science, this material has outstanding mechanical strength, high hardness, toughness, surpassing the properties of natural enamels, as well as enamel simulation materials. mass production before.
Professor Deng Xuliang at Peking University and one of the lead authors of the study said that nanocomposites have a hardness similar to natural tooth enamel, and thanks to that, the composite material has enough strength to chew, copper. while preventing tooth wear.
Moreover, nanocomposites can withstand greater vibration and impact forces, because the toughness of this material is better than natural enamel.
