Abstract
[...]the present study aimes at testing the in vitro fracture strength of Vita Enamic® crowns, comparatively with the conventionally used porcelain-veneered zirconia crowns. 2.MATERIALS AND METHODS Coblat chromium alloy (Wironit®, Bego) was used to fabricate forty replicas of a prepared mandibular first molar, divided randomly into two groups. [...]in vitro testing of a single parameter does not necessarily reflect an in vivo scenario. Clinical studies will subsequently confirm the overall in vitro outcomes. [...]natural teeth' properties cannot be replicated in vitro using synthetic materials. [...]extracted natural teeth can have considerable variation, which may interfere with the results of such an in vitro study. [...]the present investigation used metal dies replicas of prepared natural tooth to standardize the preparation and crowns' dimensions among the samples.
