[Restorative materials and initial pellicle formation].

Information concerning initial pellicle forming (dental cuticle) are possible via contact-angle determination. Not only the type of the restorative material but also its surface processing (structure) influence the initial forming of the pellicle. The higher the surface energy of a material, the more complete and quicker the masking of the surface by the initial pellicle.

[Bonding strength of adhesive resins with non-precious metal alloys in relation to conditioning methods].

The tensile strength of adhesive metal bonds of the alloys Gisadent KCM degrees, KCM 83 degrees and NCA degrees with the adhesive materials Evicrol degrees, Spofacryl degrees and ABC-Cement degrees has been determined in dependence on the conditioning methods sandblasting, electrolytic etching and Silicoater degrees treatment. The Silicoater degrees treatment was found to be the most successful conditioning method independent on the alloy and the used adhesives. After electrolytic etching increased bond strength values are to be expected particularly with Gisadent NCA degrees. Independent on the used alloy and the conditioning method Spofacryl degrees shows the best adhesive properties of the tested adhesive materials.

[The porosity, microhardness, roughness and internal stresses of PMMA base materials in relation to their isolation. 1. Porosity and microhardness].

Selected material properties of hot and cold polymerized denture basic materials (polymethylmethacrylate) were investigated after different methods of isolation: alginate, tin foil and silicone. Both tin foil and silicone isolation the handling of which is much easier result in a decreased portion of porosities and an increased microhardness in the PMMA.

[Porosity, microhardness, roughness and internal stresses of PMMA base materials depending on the isolation method. 2. Roughness and internal stresses].

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.
