Resumen
Objetivo. Comparar la estabilidad dimensional de un hidrocoloide irreversible de vaciado convencional con hidrocoloides irreversibles de vaciado extendido. Metodología. Fueron evaluados cuatro productos con indicación de vaciado extendido: Jeltrate
Plus (Denstply Sirona), Hydrogum 5 (Zhermack SpA), Algimax (Major), Kromopan (Lascod) y un producto de vaciado convencional (Tropicalgin; Zhermack SpA). Con cada producto se realizaron 10 impresiones y se vaciaron en yeso tipo III en cinco tiempos de almacenamiento diferentes (0, 24, 96, 120 y 168 horas). Un escáner para modelos tridimensionales se utilizó para digitalizar los modelos de yeso y realizar las mediciones correspondientes: sumatoria de las longitudes, variabilidad dimensional, porcentaje de variabilidad. Resultados. Las cinco marcas comerciales presentaron una sumatoria de longitudes mayor al grupo control (p<0,033). A las 0, 24 y 96h Tropicalgin e Hydrogum 5 presentaron significativamente menor variación dimensional en comparación con el modelo maestro (p<0,001). Los porcentajes de variabilidad oscilaron entre un 0.24 a 0.91%. Conclusiones. La estabilidad dimensional depende del producto utilizado. Almacenado correctamente, el hidrocoloide irreversible de vaciado convencional parece no sufrir alteraciones significativas hasta 96h, mientras que en el caso de Hydrogum 5 parece mantener su estabilidad dimensional hasta 168h.
