a B s t r a C t -The article offers a view on the outcomes of morphometric studies focusing on vertical, transverse parameters of the lower large molars in patients with various dental types of arches. The subject of the study was the lower molars segments obtained from jaws cast models of 65 people with physiological occlusion, a full set of permanent teeth and various types of dental system (Group 1 -normodontia; Group 2 -macrodontia; Group 3 -microdontia). For transversal direction morphometry, the vestibular-lingual size of the tooth crown and neck were used, as well as the intertubercular distance. To measure the vertical parameters, the height of the vestibular, lingual odontomere and that of the tubercle were identified. The results of the study show that people with physiological occlusion and permanent teeth macrodontia, the vertical, transversal parameters exceed those featured by people with normodontia and microdontia types of the dental system. The obtained odontometric features can be used through diagnosing occlusal relationships and identifying various pathological, physiological abrasions of varying degrees of occlusal surface loss.
