Abstract
Bennett movement is one of the biomechanical factors of the occlusal program, because the direction and size of the shift influence
the height o f the nodules and position o f the tooth fissure system. Individual differences only refer to the immediate lateral shift (ISS), i.e. the initial part o f the Bennett movement. The interrelationship between the occlusion organization and ISS size has not yet been fully clarified in literature reports. Therefore, the aim o f this study was to measure the ISS size in subjects with canine occlusion and centric occlusion, and to determine the possible correlation among the size o f ISS, type o f occlusion, and subject's sex and age. The study sample consisted o f 98 subjects, 68 with canine occlusion and 30 with centric occlusion. Bennett movement was registered employing a Quick Analyzer, whereas the size o f ISS was measured with a sliding caliper.No difference was found in the size o f ISS relative to sex and age, either in the total sample or within particular types o f occlusion. The mean ISS was 0.9 mm and 0.82 mm in the groups o f subjects with canine and centric occlusion, respectively.
