| Abstract (English): | Objectives: To compare the strength and length of thermoset and thermoplastic elastomeric chains. Materials and Methods: An in vitro study was performed with a sample of 72 thermoplastic and 72 thermoset chains, divided into 6 times groups (initial, 1, 7, 14, 21 and 28 days). Thirty-six templates were manufactured with 20 mm separation. To hold the chains at a constant length; they were immersed in artificial saliva. Housed in an incubator at 37° C. Force was measured with a dynamometer and length with a digital vernier caliper. Student's t test, ANOVA and Tukey's post hoc test were performed. Results: The mean initial force of the thermoset chains (309.58 g) was lower than of the thermoplastic chains, and at 28 days the thermoplastic chains (322.5 g) had a greater loss of force (46.2%) and the thermoset chains 35%. The thermoplastic chains had greater dimensional changes (49.9%) and the thermoset chains 28.6% of their initial length. The strength and length showed statistically significant differences (p<0.001) from the first day. Conclusions: The thermoplastic chains had greater initial strength, while the thermoset chains obtained a lighter but more durable strength. The thermoplastic chains showed greater length changes from the first day. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): | Objetivos: Comparar la fuerza y longitud de las cadenas elastoméricas termoestables y termoplásticas. Materiales y Métodos: Se realizó un estudio in vitro con una muestra de 72 cadenas termoplásticas y 72 termoestables, divididas en 6 grupos de tiempo (inicial, 1, 7, 14, 21 y 28 días). Se fabricaron 36 plantillas con 20 mm de separación, para sujetar las cadenas a una longitud constante; se sumergieron en saliva artificial, alojadas en una incubadora a 37 °C. La fuerza se midió con un dinamómetro y la longitud con un calibrador vernier digital. Se realizaron pruebas de t de Student, ANOVA y post hoc de Tukey. Resultados: El promedio de la fuerza inicial de las cadenas termoestables (309,58 g) fue menor que las termoplásticas (322,5 g) y a los 28 días las termoplásticas tuvieron una pérdida de fuerza mayor (46,2%) que las termoestables (35%). Las cadenas termoplásticas tuvieron mayores cambios dimensionales (49,9%) y las termoestables el 28,6% de su longitud inicial. La fuerza y longitud presentaron diferencias estadísticamente significativas (p<0,001) a partir del primer día. Conclusiones: Las cadenas termoplásticas presentan mayor fuerza inicial, mientras que las cadenas termoestables obtuvieron una fuerza más ligera pero más duradera. Las cadenas termoplásticas presentaron mayores cambios de longitud desde el primer día. [ABSTRACT FROM AUTHOR] |
