Abstract: Silicon nitride has better mechanical properties, chemical stability and biocompatibility than dental ceramic restoration materials such as alumina and zirconia, and has been used in bio-orthopedic restoration. In recent years, some scholars have introduced silicon nitride ceramics into the field of dental restoration. Based on the introduction of the performance characteristics of silicon nitride ceramics, the research progress of silicon nitride ceramic dental implants, post-core crowns and veneering porcelain were reviewed. The future research direction of silicon nitride in the field of dental restoration was also expected.
Key words: silicon nitride; dental restoration; dental implant; post-core crown; veneering porcelain
