blank group 1:Following veneer preparation, the tooth surface is cleaned and air-dried. A 37% phosphoric acid gel is applied to the enamel surface for 20 seconds, then thoroughly rinsed and dried to a
0.5mm group:Bonding of 0.5 mm thick lithium disilicate glass ceramics on isolated teeth using 5 sets of energy laser treatments (140 mJ, 160 mJ, 180 mJ, 200 mJ, 220 mJ)
0.2mm group:Bonding of 0.2 mm thick lithium disilicate glass ceramics on isolated teeth using 5 sets of energy laser treatments (140 mJ, 160 mJ, 180 mJ, 200 mJ, 220 mJ)
blank group 2:enamel surface preparation
