| dc.description | Dental resins have characteristics of strength and aesthetics to present a variety of colors, offer success and considerable longevity in restorations, although not reach the resistance that has the tooth resins have improved in composition with the use of nano technology, the aim of the research is to analyze the strength of dental restorative materials against direct application of compressive forces. preparing 30 samples was performed as following cylinders established by the ISO604 standard for polymers, three resins different commercial houses where they were subjected in a universal machine mechanical tests (Metrotec series MTE50) with a force of 50 kilonewtons calibrating a preload 0 newtons with a displacement rate of 1 millimeter per minute was chosen, applying force to achieve each sample fracture. The results of the different resins were 231 MPa for NeoFill resin, Z250 obtained 218 MPa and the resin with lower values was Brillant resin with a value of 210 megapascals although the first two showed similar results there is a statistical difference significant with Brillant; the statistics show us that are suitable for use. The results of the different resins were 231 MPa for NeoFill resin, Z250 obtained 218 MPa and the resin with lower values was Brillant resin with a value of 210 megapascals although the first two showed similar results there is a statistical difference significant with Brillant; the statistics show us that are suitable for use.

| dc.description | Las resinas dentales poseen características de resistencia y estética al presentar variedad de colores, ofrecen éxito y longevidad considerables en las restauraciones, a pesar que no logran alcanzar la resistencia que tiene el diente las resinas han ido mejorando en su composición con el uso de la nano tecnología, él objetivo de la investigación es analizar la resistencia de materiales de restauración dental frente a la aplicación de fuerzas directas de compresión. Se realizó la preparación de 30 muestras en forma de cilindros siguiendo lo establecido por las norma ISO604 para polímeros, se escogió tres resinas de diferentes casas comerciales donde fueron sometidas en una máquina universal de pruebas mecánicas (Metrotec serie MTE50) con una fuerza de 50 kilonewtons calibrándola con una precarga de 0 newtons con una velocidad de desplazamiento de 1 milímetro por minuto, aplicando la fuerza hasta lograr la fractura de cada muestra. Los resultados obtenidos de las diferentes resinas fueron de 231 MPa para la resina Neofill, la resina Z250 obtuvo 218 MPa y la resina con menores valores fue la resina Brillant con un valor de 210 mega pascales aunque las dos primeras presentaron resultados similares hay una diferencia estadística significativa con Brillant; los valores estadísticos nos muestran que son adecuados para su uso. | |
