RIBEIRO, Victor Antônio Queiroz et al. Evaluation of the marginal fit in copings for full metaloceramic crown with chamfer and beveled shoulder finish line. RFO UPF [online]. 2010, vol.15, n.3, pp. 279-283. ISSN 1413-4012.

OBJECTIVE: The purpose of this study was to evaluate the marginal fit that happen in copings for full metaloceramics crowns made in league of nickel chrome adapted to templates with chamfer and beveled shoulder finish line. METHODS: For that they were make ten you change metallic for each type of cervical termination starting from cylinders of steel simulating dental preparations for full metaloceramics crowns. The copings were adapted to the respective templates to form a body-of-evidence, and its cervical finish line analyzed before and after the cementation of the same ones with cement of phosphate of zinc, through an optical microscope aided by a system of image analysis. RESULTS: The results of marginal fit were submitted to Wilcoxon and Student's t test and it was verified that there is no statistically significant difference between the two modalities of cervical finish line. CONCLUSION: From the data obtained it can be concluded that cervical finish lines evaluated are similar in your behavior considering the marginal adaptation.
