A University of Missouri engineer and president of Nanova Biomaterials, has developed a “flowable” composite that can be injected in a cavity and hardened in less than 20 seconds through a high-intensity light. Hao Li, PhD, created longer lasting fillings for dental restoration called NovaPro Flow. The composites are comprised of calcium phosphate nanofibers. Li says it significantly improves the strength of the tooth. Nanova also developed a painless way to replace fillings using a plasma brush. In less than 30 seconds, the plasma brush uses chemical reactions to disinfect and clean cavities for fillings. In addition to the bacteria-killing properties, the “cool flame” from the plasma brush forms a better bond for cavity fillings.
