APPARATUS FOR MORPHOMETRY OF THE HUMAN CRANIO-MAXILLOFACIAL REGION AND REGISTRATION OF MANDIBULAR MOVEMENT

摘要

FIELD: medical equipment.;SUBSTANCE: invention relates to medicine, namely to apparatuses for morphometry of the human cranio-maxillofacial region and registration of mandibular movement. The apparatus comprises a supporting part made in the form of an elastic bandage. The supporting part comprises a box with a cover, installed in the frontal part on the elastic bandage. The measuring system comprises a rectangular frame located in the plane parallel to the face of the patient. The frame is equipped with a telescopic unit installed under the cover of the box, made of two L-shaped elements forming the upper side of the frame and two vertical rods in the form of the lateral sides of the frame, wherein each of the rods is equipped with a measuring scale. The L-shaped elements are connected by a flexible tube in the upper part. The frame is equipped with three horizontal rails at the bottom and in the centre, wherein each of the rails comprises a measuring scale with moving recorders for the position of the control points of the face. The horizontal rails are configured to changing the position relative to the control points of the face and the measuring scale on the vertical rods of the frame so as to allow for measurement of the height of the lower and the middle third of the face, estimation of the width of the face, type of the face and symmetry thereof. The apparatus is equipped with a unit for registering mandibular movement, containing a digital camera, a plexiglass screen attached to the middle rail of the frame of the telescopic system and equipped with a measuring grid with millimeter lines and angles. The apparatus comprises a fibre-optic sensor configured to be installed on the mandibular teeth at the contact point corresponding to the median line of the face. The sensor is connected with a laser pointer by a fibre-optic cable. The registration unit is configured to calculate the trajectory of the movement of the mandible.;EFFECT: increase in the functional capabilities of the apparatus is achieved.;1 cl, 4 dwg
