Publication number: 20230137422Abstract: Proposed is a composition for orthodontic correction and prevention and treatment of dental disorders, and the composition contains mesoporous silica particles and a zwitterionic material. The composition may reduce thickness and biomass of a saliva-derived biofilm, increase antifouling ability, and reduce viability of bacteria due to an adhesion resistance to fungi and bacteria. In addition, the composition may prevent protein adsorption, provide excellent wettability and mechanical properties, provide resistance to inflammation through amplification of SOD activity, and prevent aggregation of ceria particles. Due to the advantages stated above, a new dental material that overcomes the problems of existing dental materials may be provided.Type: ApplicationFiled: December 3, 2021Publication date: May 4, 2023Inventors: Byung Youn CHOI, Sang Hoon LEE, Mee Ae KIM, Geun LEE, Jae Sik KIM, Sung Hwan CHOI, Jae Sung KWON, Jie JIN, Ji Young SEO
