...Abstract


Introduction. Double telescopic crowns are connecting elements of partial dentures and are considered to be prosthetic devices of high aesthetic and biological value. Their basic drawback is the assessment of retention force value which has to be strong enough to balance the opposite forces but, nevertheless, must not result in harming the periodontal tissue of retention teeth while taking the denture off. The retention force is the highest immediately after the denture’s construction
and is progressively declining until the end of the “settling in phase”, i.e. until the retention force value becomes well-established.
Aim of the study was the measurement of the overall retention force of completed telescopic dentures and a survey of „settling in phase“duration.
Methods. The measuring was conducted on 20 telescopic dentures consisting of 2, 3 or 4 telescopic crowns made of gold alloy type IV and executed by dynamometer.
Results. An optimal retention force was detected in only 37% of telescopic dentures. An insufficient retention force was observed in 16%, while in the remaining 47% an excessive force was detected. In the largest number of dentures (35%) the settling in phase began after 33 cycles, which shows that this phase takes on average 10,6 days.
Conclusion. The „settling in phase“, during which retention force becomes stabilized, is completed in the first ten days after the delivery of the completed telescopic denture.

Key words:
telescopic crowns, retention force, settling in phase
