Sumita Mitra, Inventor of Filtek Nanocomposite Dental Materials at 3M, Inducted into National Inventors Hall of Fame

This year, the National Inventors Hall of Fame will be inducting a new class which includes the inventor of a dental composite material which was revolutionary for its high durability and wear resistance compared to other filling materials at that time. This Friday, May 4th, marks the 14th anniversary of the issue of one of the dental filling material patents held by Dr. Sumita Mitra, a former 3M chemical engineer responsible for the development of Filtek dental restorative material. With this patent anniversary upon us, we return again to our Evolution of Technology series to take a long view at the history of dental implants and the impact of Mitra’s contributions to this field of research.

Both consumers and companies have soon to be Hall of Fame member Mary Engle Pennington to thank… This May, Pennington will be honored along with the rest of the 2018 class of inductees into the National Inventors Hall of Fame for her technological contributions to food storage and safety. With the anniversary of Pennington’s egg preservation patent upon us, we return again to our Evolution of Technology series to take a long view at the history of food storage and the contributions of this year’s Hall of Fame inductee, a pioneering scientist and the first female lab chief at the U.S. Food and Drug Administration.
