Evaluate and Compare the Effect of Different Marginal Cement Space Parameter Setting in the CAD Software on the Marginal and Internal Fitness of Monolithic Zirconia Crowns with Different Types of Luting Agents (A comparative in vitro study)
Author(s): Eman D Hammood* and Adel F Ibraheem
Objectives: The purpose of this in vitro study was to evaluate and compare the effect of different marginal cement space parameter setting in the CAD software on the marginal and internal fitness of monolithic zirconia crowns with different luting agent. Materials and method: 48 sound human maxillary first permanent premolar teeth of comparable size and shape extracted for orthodontic purposes were collected and selected to be used in this in vitro study. All the dimensions of each crown were tested with using one way ANOVA in order to reduce the confounding variables. The teeth samples were divided into two main groups according to the different marginal cement space parameter setting (n=24) as following: Group I: 0 cement space around the margin and additional cement space of 80 Mm starting 1mm above the finish lines of the teeth. Group II.. Read More»
