[Development strategies and progress of composite resin filling material]

Composite resin filling material is the first choice for tooth direct bonding restoration. Its good performance can meet the requirements of clinical tooth repair treatment. It is used to restore the structure, aesthetic and function of defected teeth with a way of minimally invasive intervention. To further improve its clinical efficacy, the fundamental strategy is to ameliorate the limitation of material properties. Based on the summary of current research progress, this article focuses on the property of improved composite resin material, and the progress of developing novel resin material including antibacterial composite resin, bioactive remineralizing resin as well as self-healing resin, so as to provide innovative ideas for the future research of new composite resin filling materials.
