Evaluación termo-mecánica de composites dentales fotopolimerizables
Palavras-chave:
composites dentales fotopolimerizables; aerosil OX50; nanorelleno; temperatura de transición vítrea.Resumo
El objetivo del estudio fue evaluar las propiedades termo-mecánicas de seis composites
dentales fotopolimerizables, preparados utilizando aerosil OX50 como relleno inorgánico y
dos matrices: Bis-GMA/dimetacrilato de tetraetilenglicol/-metacriloxipropiltrimetoxisilano y
Bis-GMA/dimetacrilato de trietilenglicol/-metacriloxipropiltrimetoxisilano. El sistema
iniciador fue el par canforquinona/metacrilato de N,N-dimetilaminoetilo. El relleno se
caracterizó por Espectroscopia Infrarroja a transformada de Fourier, Difracción de rayos-X y
Microscopía Electrónica de Barrido. Los composites se evaluaron mediante Análisis
Termogravimétrico y Análisis Mecánico Dinámico. Se corroboró que el aerosil OX50 es un
dióxido de silicio amorfo, formado por partículas esféricas de tamaño nanométrico. Los
composites experimentales son térmicamente estables hasta los 300 °C, lo que resulta
apropiado para su aplicación. Tres de ellos presentan módulos y temperaturas de transición vítrea adecuadas, ambos parámetros son ligeramente superiores a los del composite comercial
Tetric Ceram ® . Teniendo en cuenta los resultados obtenidos, es posible utilizar los
dimetacrilatos de tretratilenglicol y trietilenglicol en la preparación de los composites dentales
experimentales.
