Evaluation of the marginal fit in copings for full metaloceramic crown with chamfer and beveled shoulder finish line

Abstract

Objective: The purpose of this study was to evaluate the marginal fit that happen in copings for full met- aloceramics crowns made in league of nickel chrome adapted to templates with chamfer and beveled shoul- der finish line. Methods: For that they were make ten you change metallic for each type of cervical termina- tion starting from cylinders of steel simulating dental preparations for full metaloceramics crowns. The cop- ings 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 micro- scope 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 statis- tically significant difference between the two modali- ties 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.
