Tiivistelmä
This study aimed to compare optical properties and failure Ink of leucite IPS impress CAD DT) and lithium disilicate glass ceramic VS e.max CAD Li) fildiCriaiS in incisor veneers, Four groups of VCOCCIS were made on 36 bovine incisors with Ccrcc 3D milling unit (n,Wgroup): 0,5 and 0,3 nun thick leucite glass and 0,5 and 0,3 nun lithium disilicate glass veneers, the optical features were measured with CM-700d spectrophotometer using white and yellow try-in pastes. Differences were determined by means of AE value and luminance. The bovine teeth with veneers were mounted an acrylic resin blacks (Dhows& Heraeus Kritzer) 3fld sUic loading test Was conducted (LR3OK phis. Lloyd Instruments). The color difference of veneers could be noticed with yellow and white cements when the material thickness increased from 03 to 0.5 min (leucite yellow 4.4, white 6.0: lithiumdisilicate A yellow 21 white 4,0. 130th materials showed similar failure load with 0,5 min veneers (leucite 19(16 1-319 N: 2098 309 N), The laid ire load of 03 mm thick lithium dilisilicalc veneers (2002 +/- 427 NJ was comparable with the 0.51nin veneers. illiraihin lithium disilicate glass ceramic veneers (0.3 mm) could be a potential option far clinical use.
