title: [Porosity, microhardness, roughness and internal stresses of PMMA base materials depending on the isolation method. 2. Roughness and internal stresses].
abstract: In the present paper hot and cold polymerized denture basic materials were investigated after isolation by means of alginate, tin foil and silicone. Measurements of roughness and internal stresses after polymerization show that the advantages of a silicone isolation correspond to those of a tin foil isolation, where the clinically important smoothing effect of a silicone isolation is convincing using simple laboratory handling.
