Sažetak
The mechanism of the occurrence of fissures and splits causing a
partial or complete lack of crown in human teeth is extremely complex and as yet inadequately studied, although the treatment of these lesions has been widely introduced in daily dental practice. Many studies con­ducted so far point to different approaches to the problem, but studies on cyclic loads and dynamic tooth strength have been neglected. In this study, the effect of cyclic loads on the facet crown of filled premolares was assessed in 32 healthy teeth using a modified Amsler's high-frequency pulsator. The upper limit of the dynamic strength of pre­molars was found to be 1600 N, whereas permanent dynamic load for this group of teeth was 300 N. Using a dynamic strength diagram, the number of cycles for particular loads, ranging from 300 to 1600 Newtons, required for a fissure to occur was determined.
