Morphological investigation of various orthodontic lingual bracket slots using scanning electron microscopy and atomic force microscopy.

abstract：:The dynamic transmission electron microscope (DTEM) is introduced as a novel tool for in situ processing of materials. Examples of various types of dynamic studies outline the advantages and differences of laser-based heating in the DTEM in comparison to conventional (resistive) heating in situ TEM methods. We demonst...
