Sažetak
Cements used for seating fixed dentures are expected to have some definite resistance to tearing off and impact loads. It seems that these features may significantly influence the effective adhesion of a crown or bridge. For final seating of dentures both phosphate and glassionomer cements, which are a more recent invention, are used.
The aim of this work was to compare two cements from the phosphate group with two cements from the glassionomere group with respect to their tearing off resistance and resistance to impact loads. The experiment was conducted in vitro. In the test for
tearing off resistance Osteoplant implant was used as the abutment. The crown was a cast chrome- nickel substructure. The Raustein FM 250 was used for registration of this phenomenon. Six tests for tearing were conducted for each cement. A special device was constructed to test resistance to impact loads. The abutment was made of brass. After coating with a layer of varnish the substructure was contoured as a wax pattern and then cast in Remanium CS
alloy. This metal substructure had additional handles for easier manipulation. Six tests were made for each material. When analyzing the results we found significant differences between the values of tearing resistance of the cements from the two groups (the average tearimg resistance for 1. Harv. Phosp. 183.3 N; 2. Poscal 273.5 N; 3.
Rely X 27.8 N; 4. GC Fuji I 19 N). Significant differences were also observed when impact load resistance was tested.
