Description

Compatibility between impression materials (agar and alginate) and model stones (dental and high strength dental) used for the combined agar-alginate technique was investigated, measuring detail reproduction and surface roughness of dental stone models made by each combination. Our experimental results were as follows: In combination with agar and model stones, 4 of 24 sets of dental stones and nothing of 30 sets of high strength dental stones were evaluated as the best rank of both detail reproductions and surface roughness. On the other hand, in the case of alginate and model stones, it was given to 10 of 20 sets of dental stones and 2 of 25 sets of high strength dental stones. Accordingly, the compatibility between dental stones and both impression materials was better than of high strength dental stones, and the combination of alginate with model stones showed a preferable compatibility.
