Cementos odontológicos a base de Poli (ácido acrílico) y wollastonita

Abstract

[ES] Los cementos de polialcanoatos o iomómeros de vidrio son materiales que han sido utilizados con éxito durante más de 20 años en trabajos de odontología. Un problema que presentan dichos cementos es la liberación de iones Al3+ al medio fisiológico, lo que puede dar lugar a daños irreversibles en los pacientes. Con el propósito de evitar dicha liberación, se han preparado y caracterizado cementos obtenidos a partir de la reacción entre el ácido poliacrílico y la wollastonita (CaSiO3) en una solución acuosa de ácido tartárico. Los resultados obtenidos han puesto de manifiesto que estos cementos alcanzan resistencias a la compresión similares a las de los cementos de polialcanoato o ionómeros convencionales. Adicionalmente, los cementos resultantes son biocompatibles y bioactivos.

[EN] The glass ionomer cements have been used successfully in dentistry for more than 20 years. A problem of these cements is the release of Al3+ ions to the physiological medium, being able to cause irreversible health problems to the patients. With the purpose of avoiding this problem, cements, from the reaction between the polyacrylic acid and wollastonita (CaSiO3) in a water solution of tartaric acid, have been obtained and characterized. The results have shown that these cements reach compression strength values similar to those of the conventional cements of vitreous polyalqueonate. Additionally, the obtained cements are biocompatibles and bioactives.
