Abstract
1. Способ определения угла наклона нижней челюсти, включающий проведение конусно-лучевого томографического исследования челюстно-лицевой области с использование рентгеноконтрастных маркеров, расчет положения нижнего зубного ряда относительно шарнирной оси головок нижней челюсти, отличающийся тем, что используют рельефные рентгеноконтрастные маркеры, фиксируемые на зубах нижней челюсти, с помощью стандартной программы-просмоторщика компьютерных томограмм переносят проекцию стандартной артикуляторной шарнирной оси на проекцию индивидуальной шарнирной оси головок нижней челюсти, выстраивают виртуальную систему координат, проходящую через проекцию артикуляторной шарнирной оси, и рассчитывают длину отрезков, соединяющих рентгеноконтрастные маркеры и центры осей координат и углы между этими отрезками и вертикальной осью координат.2. Устройство для переноса гипсовых моделей в пространство артикулятора, отличающееся тем, что длину и углы телескопических указателей устройства настраивают по данным, полученным при анализе конусно-лучевых компьютерных томограмм, а гипсовую модель нижней челюсти в пространстве артикулятора устанавливают в заданном положении и под определенным углом по отношению к стандартной артикуляторной шарнирной оси.1. The method of determining the angle of inclination of the lower jaw, including conducting a cone-beam tomographic examination of the maxillofacial region using radiopaque markers, calculating the position of the lower dentition relative to the hinge axis of the heads of the lower jaw, characterized in that they use relief radiopaque markers fixed on the teeth of the lower jaws, using the standard computer tomogram viewer program, transfer the projection of the standard articulatory articulated axis to the projection ind the virtual hinge axis of the heads of the lower jaw, a virtual coordinate system is built that passes through the projection of the articulatory hinge axis, and the length of the segments connecting the radiopaque markers and the centers of the coordinate axes and the angles between these segments and the vertical coordinate axis are calculated. 2. A device for transferring gypsum models into the space of an articulator, characterized in that the length and angles of the telescopic pointers of the device are adjusted according to the data obtained in the analysis of cone-beam computed tomograms, and the gypsum model of the lower jaw in the space of the articulator is set in a predetermined position and at a certain angle with respect to to the standard articulator articulated axis.
