Bond Strength of Orthodontic Brackets to Temporary Crowns: In vitro Effects of Surface Treatment

Neal B Kedia et al. J Pharm Bioallied Sci. 2023 Jul.

Abstract

Background: To evaluate bond strength of orthodontic brackets to temporary crowns.

Materials and methods: A bis-acrylic composite was used to create a total of 25 discs, which were then divided into five groups based on how their surfaces were treated with black, blue, green, and sandblasted diamond burs, in addition to a control group. Software called SPSS was used to analyze the outcome.

Results: The average pressures measured for the green bur, black bur, and sandblasting, respectively, were 12.05 MPa, 12.87 MPa, and 19.25 MPa. Comparing the control and blue groups, a substantial variation in shear bond strength was only noticed with reference to sandblasting.

Conclusion: The binding strength of orthodontic brackets is increased by sandblasting temporary crowns.

Keywords: Shear bond strength; surface treatments; temporary crowns.
