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

The glass ionomer cements have been used successfully in dentistry for more than 20 years. A problem of these cements is the release of Al 3+ 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 (CaSiO 3 ) 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.
