AT&M Biomaterials Co., Ltd. undertook a research project on dental material manufacturing technology in the National 863 Scientific Research Plan, and worked closely with teams from Peking University School of Stomatology and West China University of Medical Sciences to jointly develop patented technologies for 'dental polymer-based filling and restoration materials' and 'methods of using nanofibers to reinforce and toughen resin matrix composites'. AT&M Biomaterials Co., Ltd. is the first company in China to obtain the registration certificate for dental filling resin (NanoFiL@light-cured composite resin). Among the many dental material products on the market, NANOFIL light-cured nano-resin products have become the first products in the country to obtain a Class III dental resin registration certificate. The products produced by AT&M Biomaterials Co., Ltd. are sold in more than 100 countries abroad, including light-cured composite resin, dental phosphate etchant gel, light-cured composite flowable resin, dental pit and fissure sealant, dual cure core resin cement, dental bonding agent, glass ionomer luting cement, dental silicone rubber impression materials, etc.
