Sažetak
Retention o f a partial denture is the resistance of retaining elements
to forces which endeavour to dislodge it from its base. Basic retention is obtained by means o f clasps, attachments, diaphragms, telescopic crowns, magnets etc. The aim of the present study was to determine the dynamics o f reduced retention forces in CEKA attachments (OL 694). An instrument, especially constructed for the purpose, was used to measure retention forces, and the test was carried out with and without the addition o f saliva. The results of the study, which are presented graphically and in tables, and described by exponential law, show that at the commencement o f the test the value of retention force in the attachment, without the addition o f saliva, amounted to approximately 10.2 N, and after 1200 cycles o f insertion and removal, 3.4 N. With the addition o f saliva the retention force o f the attachment amounted to 9.92 N at the commencement o f the test and after 1200 cycles o f insertion and removal, 5.12 N. A fundamental factor which has a cardinal effect on the extent of the retention force is wear and fatigue o f the material. Although in this study no significant differences in the reduction o f retention fo rces
were found than had been anticipated, it is recommended that special attention should be paid to the choice of retention technique in partial dentures.
