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).
