Hybrid TiO₂/Al₂O₃ nanolayer overcoating enhances dental lithium disilicate glass-ceramics acid resistance and surface mechanical properties.

ABSTRACT: Lithium disilicate glass-ceramics are increasingly utilized in dental applications due to their exceptional optical and aesthetic properties. However, lithium disilicate glass-ceramics possess a mixed crystalline and amorphous structure with variable resistance to external corrosion. Exposure of lithium disilicate glass-ceramics to acidic conditions in the oral cavity leads to pore formation, and the risk of cracking increases with long-term wear. Herein, we employed atomic layer deposition to precisely coat the TiO₂/Al₂O₃ hybrid nanolayer on the surface of lithium disilicate glass-ceramics to enhance acid resistance and surface mechanical properties. The TiO₂ species play crucial roles in improving acid resistance, and the Al₂O_3<
