Effect of sandblasting, etching and resin bonding on the flexural strength/bonding of novel glass-ceramics

Leucite (KAlSi2O6) glass-ceramics are desirable for the fabrication of dental restorations due to their excellent aesthetic properties, which simulate natural tooth appearance and their low cytotoxicity [1]. The high thermal expansion coefficient of tetragonal leucite (20.5 ×10−6/°C) [2], makes it a useful component in veneering materials for high strength metal-ceramic restorations [3]. Leucite glass-ceramics can also be fabricated into a variety of all-ceramic restorations adhesively bonded to dentine–enamel tooth structure [4,5], and encouraging a more conserv ative tooth preparation [6].
