Abstract
Statement of problem. There have been few studies about the marginal fit of Auro Galvano Crowns.
Purpose. The purpose of this study was to compare the marginal fit of the anterior single restorations.
Material and methods. The in vitro marginal discrepancies of metal-ceramic, Auro Galvano Crown and coping were evaluated and compared. The Auro Gavano Crowns were made from one extracted maxillary central incisor prepared by milling machine. 30crowns per each system were fabricated. Measurements of a crown were recorded at 50 points that were randomly selected for marginal gap evaluation. Parametric statistical analysis was performed for the results.
Results. Mean marginal gap dimensions and standard deviations at the marginal opening for the anterior single crowns were 74±21mum for the control (metal-ceramic restoration), 45±11mum for Auro Galvano Crown coping, and 51±9mum for the Auro Galvano Crown.
Conclusions. Auro Calvano Crown showed significantly smaller (P<.05) marginal gap than the control. Ceramic application did not significantly affected the marginal fit of Auro Galvano Crown. (P>.05)
