Abstract

Abstract: Objective: To analyze the surface topography and surface elements of two metal brackets after clinical application. Methods: The scanning electron microscope was used to observe the slot surface morphology before and after orthodontic treatment. X-ray energy-dispersive spectrometry was used to test the elemental composition of the surface. Results: After clinical use, traces of friction and wear and different plaque accumulation could be found on the bracket surface. However, the surface element did not change much. Conclusion: After exposure in mouth, the elemental composition on the metal surface changed little without significant ion deposition and release phenomenon.

Key words: Orthodontic brackets, Retrieval analyses, Surface morphology
