Ytterbium Fluoride (YbF₃) is incorporated into dental composites to provide radiopacity, allowing for clear identification of the restoration area during X-ray imaging. At the same time, YbF₃ offers high transparency, preserving the natural appearance of the restored tooth. Sukgyung AT's YbF₃ series delivers the highest level of transparency and superior radiopacity available in the market today and is already trusted by leading global manufacturers of dental composites. In addition, a variety of particle sizes and surface-treated options are available, enabling tailored solutions to meet specific customer needs.
