Comparison of the shear resistance of metal and ceramic brackets using conventional or self-etching adhesive. In vitro study year 2021

Abstract

An in vitro study was conducted comparing the strength of metallic and ceramic brackets using two types of adhesive: conventional adhesive with acid etching of the surface and the latest-generation self-etching adhesive. The shear force resistance was measured in the laboratory. The results showed that metallic brackets bonded with conventional adhesive had better results than those bonded with self-etching adhesive, while ceramic brackets showed only a slight difference. The brackets bonded with self-etching adhesive showed a minimal difference compared to those bonded with conventional adhesive.

Se realizo un trabajo in vitro comparando la resistencia de brackets metálicos y ceramicos con dos tipos de adhesivo, el adhesivo convencional con previo grabado acido de Ia superficie y el adhesivo de última generación de autograbado y con ello se midió la resistencia a la fuerza de cizallamiento en el laboratorio, se obtuvo como resultado, que los brackets metálicos adheridos con adhesivo convenclonal tuvieron mejores resultados a adheridos con autograbado mientras que los brackets ceramicos tuvieron ligeramente una diferencia, los adheridos con adhesivo de autograbado presentaron diferencia mínima a comparación de los adheridos con adhesivo convencional.
