В ходе исследовательской работы была проведена оценка морфологических характеристик неорганического наполнителя пяти коммерческих и одного экспериментального стоматологических реставрационных композитных материалов, содержащих наноразмерные частицы, с помощью с помощью сканирующего электронного микроскопа Tescan Vega 3 LMH (Tescan, Брно, Чешская Республика). При проведении сканирующей электронной микроскопии было выявлено, что исследуемые образцы импортных пастообразных композитных материалов имели наполнители сходные по форме и размеру: преполяризованные конгломераты иррегулярной формы от 3 до 40 мкм, состоящие из наноразмерных сфер менее 200 нм, и отдельные сферические частицы размером до 200 нм. Преполяризованный наполнитель в низкомодульном (текучем) импортном композите имеет меньший диаметр от 3 до 30 мкм и более правильную сферическую форму. Филлеры композитных материалов российского производства имели оскольчатую форму частиц, часть наполнителя составляли кластеры микронного размера от 5 до 30 мкм, которые были образованы наноразмерными сферическими частицами менее 100 нм. Экспериментальный композитный материал имел в своем составе микросферы с диапазоном размеров от 5 до 20 мкм, состоящие из наноразмерных частиц сферической формы до 450 нм. По морфологической структуре экспериментальный композит сопоставим с наполнителями современных импортных коммерческих стоматологических композитных материалов.

In the course of the research work, the morphological characteristics of the inorganic filler of five commercial and one experimental dental restorative composite materials containing nanosized particles were assessed using a Tescan Vega 3 LMH scanning electron microscope (Tescan, Brno, Czech Republic). Scanning electron microscopy revealed that the studied samples of imported paste-like composite materials contained fillers similar in shape and size: prepolarized conglomerates of irregular shapes ranging from 3 to 40 µm, consisting of nanoscale spheres less than 200 nm in size, and individual spherical particles up to 200 nm in size. The prepolarized filler in the low-modulus (flowable) imported composite had  a smaller diameter of 3 to 30 µm and a more regular spherical shape. The fillers in the Russian-produced composite materials had fragmented particles, with some of the filler consisting of micron-sized clusters ranging from 5 to 30 µm, formed by nanoscale spherical particles less than 100 nm in size. The experimental composite material contained microspheres ranging in size from 5 to 20 µm, consisting of nanoscale spherical particles up to 450 nm in size. In terms of morphological structure, the experimental composite is comparable to fillers of modern imported commercial dental composite materials.
