Elemental, microstructural, and mechanical characterization of high gold orthodontic brackets after intraoral aging


Hersche, Sepp; Sifakakis, Iosif; Zinelis, Spiros; Eliades, Theodore (2017). Elemental, microstructural, and mechanical characterization of high gold orthodontic brackets after intraoral aging. Biomedizinische Technik. Biomedical engineering, 62(1):97-102.

Abstract

The purpose of the present study was to investigate the elemental composition, the microstructure, and the selected mechanical properties of high gold orthodontic brackets after intraoral aging. Thirty Incognito™ (3M Unitek, Bad Essen, Germany) lingual brackets were studied, 15 brackets as received (control group) and 15 brackets retrieved from different patients after orthodontic treatment. The surface of the wing area was examined by scanning electron microscopy (SEM). Backscattered electron imaging (BEI) was performed, and the elemental composition was determined by X-ray EDS analysis (EDX). After appropriate metallographic preparation, the mechanical properties tested were Martens hardness (HM), indentation modulus (E
