Glass ionomer materials have been successfully used as filling material within their area of indication for many yeras. Their ability to release fluoride ions is one of the main reasons for this. Nonetheless, there is substantial demand for an alternative that offers both fluoride release and increased flexural strength.
Compared with glass ionomer, Cention N provides tooth-coloured esthetics and exceptionally high flexural strength. The latter is especially useful for fillings in the posterior region.
This innovative self-curing filling material has been designed for the complete and permanent replacement of tooth structure. The material belongs to the materials group of alkasites and contains a patented alkaline filler that increases the release of hydroxide ions to regulate the pH value during acid attacks. As a result, demineralization can be prevented more effectively. In addition, the increased release of fluoride and calcium ions forms a sound basis for the remineralization of dental enamel.
Consistent release of ions over several years
In recent in-vitro studies, Cention N showed a consistent release of calcium and fluoride over three years. In addition, the enamel surfaces in the vicinity of the Cention N restorations exhibited a higher surface hardness than the enamel close to non-ion releasing materials. It can therefore be concluded that the ion release had a diminishing effect on the demineralization of enamel.
