Abstract
In pursuit of superior esthetics, superb biocompatibility and favorable properties, the use of high-leucite ceramic materials has increased in clinical practice and research. Because of the brittle nature of all-ceramic restorations made of IPS Empress, these restorations have the potential to fracture. Repairing ceramic-based restorations with composite resin can increase the clinical longevity of failed restorations and offer the dentist and patient a cost-effective alternative to replacement. Bonding of composite resin to ceramic restorations is highly dependent on obtaining a reliable bond, which relies on treatment of the ceramic intaglio surface. Different mechanical and chemical surface pretreatments have therefore been recommended to improve the bonding of composite to high-lucite ceramic restorations. However, it remains debatable as to which regimen provides the highest bond strength. The aim of this in-vitro study was to evaluate the effect of different surface treatments on shear bond strength to composite resin of a commercially available high-leucite ceramic (IPS Empress) at 24 hours and 6 months of water storage.
