Adhesion between orthodontic bracket and dental ceramics

Abstract

The strength of the connection between orthodontic brackets and sandblasted dental ceramics was evaluated. The strength of the bracket-ceramics connection was determined in four time intervals. Based on the obtained results, basic statistics were calculated. For the comparative analysis of average values, the following were used: ANOVA analysis of variance and Tukey’s HSD post-hoc test at the significance level of α = 0.05. The statistical analysis performed did not show any influence of the method of surface treatment (with sanding, without sanding) between orthodontic brackets and ceramics. At the same time, it has been shown that with samples storing time in aqueous environment, the quality of the connection decreases significantly, regardless of the surface treatment method used.
