Influence of Dentin Bonding Techniques on the Fracture Strength and Fracture Mode of Thin Occlusal Glass-Ceramic Veneers

This study was designed to measure the fracture strength and determine the failure mode of all-ceramic occlusal veneers fabricated from lithium disilicate and adhesively bonded to exposed dentin and to compare the fracture strength of the groups that followed the immediate dentin sealing to those that were conventionally bonded. Additionally, the influence of artificial aging and etching protocol were evaluated. Moreover, changes in the tooth structure, luting resin layer and ceramic before and after the artificial aging were analyzed.
