[Dimensional stability of impression materials studied with Talysurf 10]. / Studio sulla stabilità dimensionale di alcuni materiali da impronta con il Talysurf 10.

The dimensional stability of certain modeling elastomers was investigated. In order to obtain a complete picture, 2 samples of each elastomer class on the market (polysulphuric, polyether, silicone additives, condensation silicone), a total of 8 products, were tested according to the criteria outlined in ADA 19. In contrast with ADA 19 recommendations, measurements were taken using a Talysurf 10, a roughness meter that can also check for straightness, which was chosen as being equally efficient as other methods while offering highly reliable objectively verifiable data.
