Morphometric variability of mandible linear characteristics depending on level of teeth alveolus position

Abstract

The goal was to define morphometric variability of altitude and thickness parameters of alveolar part of a mandible depending on level of teeth alveolus position. Material and Methods ― The study was carried out using 70 passported skulls with mandibles of adults aged 21-60 years and 30 isolated mandibles excluding sex and age from scientific craniological collection of fundamental museum of human anatomy department of Saratov State Medical University n.a. V.I. Razumovsky (Saratov, Russia). Craniometrical method was used to study parameters of both sides of a mandible: altitude – from base of mandible to level of apex of medial incisors, canine, 1st and 2nd premolars, 1st, 2nd and 3rd molars; thickness – in vestibular-lingual direction at the same levels. Results and Conclusion ― The highest altitude was marked at levels of incisors and 3rd molar, the smallest one – at level of 1st and 2nd molars; maximum mandible thickness was defined at level of 2nd molar, minimum – at levels of canine and 1st – 2nd premolars on both sides of mandible; average thickness was revealed at levels of incisors, 1st and 2nd molars and had the same statistical values. Bilateral variability of thickness was significantly dominating on the right side and only at levels of 1st – 2nd premolars and 1st molar. Average values of altitude and thickness from both sides of mandible and at all levels had medium degree of variability.
