Abstract: Denture soft lining material is a kind of resin-based or silicon-based elastic liner, which can help the uniform distribution of occlusal load, reduce local excessive stress and improve patients′ comfort level. It is often used in removable denture restoration. However, the surface structure and properties of soft lining materials can easily lead to microbial adhesion and colonization, especially Candida albicans, which can lead to denture stomatitis. Therefore, the antibacterial modification of soft lining material can greatly improve its clinical application value. At present, main measures include adding antibacterial fillers, such as traditional antimicrobial agents, natural extracts, inorganic metal antimicrobial agents, photodynamic antimicrobial chemotherapy, protective non-thermal plasma treatments and so on. In this paper, main measures and progress of research on antibacterial modification of denture soft lining materials were summarized, and its antibacterial mechanism and effect on the physical and chemical properties of materials were discussed.

Key words: soft lining material, denture stomatitis, antibacterial properties
