The effect of internal roughness and bonding on the fracture resistance and structural reliability of lithium disilicate ceramic

Lithium disilicate is a synthetic glass ceramic that is being used in dentistry for many years to restore decayed or worn down teeth. It is a popular restoration material as it results in good esthetic and mechanical properties [1,2]. Additionally it present two major advantages: (1) allow the manufacturing of monolithic restorations, that do not require a veneering layer which is known to be susceptible to chipping [3,4], and (2) that a good adhesion to dental tissues can be established [5,6]. In comparison to earlier glass ceramics like feltspathic and leucite reinforced it has a higher flexural strength [7,8], and compared to oxide ceramics like zirconia it has better optical properties.
