Resumen
RESUMEN: la odontología adhesiva ha avanzado mucho desde sus comienzos. los materiales y
técnicas han cambiado y un ejemplo de esto es la aparición de los postes de fibra de vidrio y
los agentes de cementación de resina duales autograbantes. los cementos de resina están
indicados para la cementación de postes de fibra y juegan un rol fundamental en su éxito. A
pesar de las ventajas de los cementos de resina, algunos odontólogos continúan usando
cemento de vidrio ionómero para la cementación de postes de fibra. El propósito de este
estudio es comparar la resistencia a la tracción de postes de fibras de vidrio (Relyx fiber post
de la empresa 3M) cementados con dos cementos de resina duales autograbantes (Biscem de
la empresa Bisco y Relyx Unicem de la empresa 3M) y un cemento de vidrio ionómero (Ketac
Cem de la empresa 3M). A partir del presente estudio se puede concluir que los postes de fibra
de vidrio cementados con cemento de resina dual autograbante (Relyx Unicem y Biscem)
presentan significativamente mayor resistencia a la tracción que los cementados con vidrio
ionomero (Ketac Cem). Esto puede deberse a que los agentes de cementación evaluados
presentan distintas propiedades y diferentes capacidad de unión a los postes de fibra de vidrio
ya la dentina del conducto radicular.
ABSTRACT: The adhesive odontolgy in fixed prothesis has advanced very much from his beginning. The materials and technologies have changed and an example of this is the appearance of the glass fiber posts and the self etching dual cured resin luting cement.Jhe adhesive resin system are indicated in the setting of this fiber posts and playa fundamental role in your success. In spite of the advantages of the adhesive resin system, sorne dentists have continued using the glass - ionomer cement as material of fixation in glass fiber posts. The purpose of this study is compares the resistance to the traction of the fiber glass posts (Relyx fiber post of 3M company) cemented with two adhesives resin systems (Biscem cement of Bisco Company and Retyx Unicem cement of 3M company) and glass - ionómer cement (Ketac Cem cement of 3M company). From the present study it is possible to conclude that the posts of glass fiber cernented with self etching dual cured resin luting cements (Relyx Unicem and Biscem) present significantly major resistance to the traction that the cemented ones with glass - ionomer cement (Ketac Cem). This can owe to that the agents of cementation evaluated present different properties and different capacity of union to the glass fiber posts and to the dentine of the root canal.
