AT&M Biomaterials Co., Ltd. undertook a research project under the National 863 Scientific Research Plan.? Based on the research with West China University of Medical Sciences, AT&M Biomaterials Co., Ltd. worked closely with the team of Peking University School of Stomatology, combined with the patented technology of polymer-based filling and restorative materials developed by Peking University Stomatological Hospital in the project of "Oral Hard Tissue Repair Materials Research and Development and Clinical Key Technologies" and the patented technology of "Method of Nanofiber Reinforced and Toughened Resin-Matrix Composite Materials"? (CN-101397372-B), to produce internationally advanced dental polymer-based filling and restorative materials - NANOFIL light Cured composite resin. AT&M Biomaterials Co., Ltd. won the Beijing Independent Innovation Product Certificate. In 1988, AT&M Biomaterials Co., Ltd. developed dental amalgam capsules. This product fills the national technology gap. AT&M Biomaterials Co., Ltd. participated in formulating relevant national standards for dental amalgam products.? Since 2002, AT&M Biomaterials Co., Ltd. has developed a series of new high-performance dental materials. The light-curing nano-resin developed by AT&M Biomaterials Co., Ltd. has become the first dental resin product in the country to obtain a Class III registration certificate. The products sell well in more than 100 foreign countries,? such as light-curing composite resin, dental phosphoric acid etching gel, light-curing composite flowable resin, dental pit and fissure sealants, DC core composites, dental bonding agent, glass ionomer luting cements, dental vinyl polysiloxane impression materials, etc.
