Assessment of the survival and success rates of lithium disilicate crowns after different surface finishing procedures: An in vitro study.

Statement Of Problem: Evidence is limited for the impact of clinical adjustments and polishing on the longevity of glazed lithium disilicate restorations.

Purpose: The purpose of this in vitro study was to evaluate the influence of surface finishing on the survival and success rates of lithium disilicate restorations based on fatigue resistance and failure mode.

Material And Methods: Lithium disilicate (IPS e.
