Prosthodontics is a discipline that restores the shape, function and aesthetics of defective or missing teeth through artificial prostheses. Currently, commonly used clinical materials include metal alloy, resin composite and glassceramic. Glass-ceramic has the advantages of aesthetics, good biocompatibility and adjustable mechanical properties, and is widely used in clinical practice. However, its high brittleness and fracture susceptibility, together with thermal mismatch and processing challenges, warrant further clinical investigation. This article reviews the application progress of glass-ceramic in prosthodontics, covering material classification, current clinical application status and performance improvement technologies, aiming to systematically analyze the deficiencies of existing research and provide a theoretical reference for the development of highly reliable glass-ceramic prostheses.
