[Dimensional stability of alginate impressions after immersion disinfection with Impresept].

With an experimental design near clinical conditions the alginates Alginoplast, Blend-a-print, Blue-print, Palgaflex and Xantalgin were examined under the influence of the disinfection with Impresept (Espe). The absolute means of the differences between models from disinfected or nondisinfected impressions reached from 0.05%lin to 0.19%lin. In comparison to the specific tolerances of the materials the influence of Impresept on the dimension stability is not important.
