The Effect of Crown Fabrication Materials on Wear Resistance and Retention Strength: An Experimental Study Using Statistical Analysis and Magnetic Resonance Imaging

Abstract

In vitro study investigates how crown materials affect retention strength and wear resistance in this study. The researchers produced thirty crown samples from zirconia, porcelain, and lithium disilicate before cementing them on standard dental models. Through Magnetic Resonance Imaging (MRI) researchers examined the surface structure while a mechanical friction simulation evaluated wear resistance. After the wear testing procedure, the analysis was performed. A universal testing machine was used to measure the retention strength. Researchers conducted Tukey post-hoc testing in addition to regression analysis and one-way ANOVA for their statistical analysis. From the data analysis, it was clear that material selection plays a crucial role in clinical crown durability, as evidenced by significant differences in wear resistance and retention
