Iranian Scientists Use Nanotechnology to Increase Strength of Dental Crowns
“Fiber dental posts, under the brand name of AtraPost, which will soon be presented to the market, have been made as a result of a combination of advanced technologies in the production of polymer and dental materials,” said Mohammad Atayee, the managing director of the knowledge-based company.
Noting that the product consists of a polymer matrix made of epoxy and glass reinforcing fibers, he said, “In this innovative design, the glass fibers are stretched longitudinally by pultrusion, which provides high strength and durability of the posts.”
“To improve the radiographic performance, AtraPost is equipped with a thin stainless steel rod that facilitates its detection and observation in radiographic images,” Atayee said.
“The use of nanomaterials in the structure of dental adhesives not only improves product performance, but also can also create a fundamental transformation in the maintenance and care of dental crowns,” he added.
In a relevant development in January, a company in Iran had also succeeded in manufacturing nanocomposite dental cement based on zinc phosphate with high anti-corrosion and antibacterial properties for tooth restoration.
“Nanocomposites are the latest generation of dental composites that enjoy higher strength and resistance than other composites,” Nazanin Farhadyar, the managing director of the knowledge-based ‘Nano Pouyesh Yekta Nano’ company, told ANA.
“Conventional non-nano zinc phosphate cements are not antibacterial and are less hard than other cements due to their low thickness, but the nano zinc phosphate composite made in our company has high anti-bacterial and anti-corrosion properties and is used as a dental cement for orthodontics, bridges and restoration,” she added.
Development and production of nano materials, different types of special and custom nano catalysts, nano absorbents, nano fibers, natural polymer nano capsules, and metal nano oxides, and holding specialized courses in the field of commercialization of nano products, start-up of new nano technologies and safety of nano materials are other activities of the knowledge-based company.
