SU1600749A1 - Articulator and device for adjusting installation of upper and lower jaw models into central occlusion position - Google Patents

Abstract

This invention relates to medicine. The aim of the invention is to improve the accuracy of modeling the position of the simulators of the lower and upper jaws. The device contains a stand, a support plate, a transverse bracket, segments with mounting pads, as well as a device for adjusting the installation of the models of the upper and lower jaws to the central occlusion position, containing a U-shaped frame 36 with a slider 37, a spoon 38, a mechanism for linear and angular movement it and the scale 40, pointed probes 41 and probes 42. By adjusting the relative position of the installation sites, it is possible to increase the accuracy of modeling the position of the lower and upper jaw simulators. 17 il.

Claims (2)

Claim 1. An articulator containing a stand installed in the base plate, simulators of the temporomandibular joint, upper and lower bases for placement of simulators of the upper and lower jaws, nodes for adjusting their relative position and a transverse bracket, characterized in that, in order to improve the accuracy of position modeling imitators of the lower and upper jaws, an additional bracket with an indicator arrow is introduced into it, a spring installed between the bases, while the lower base is made in the form of articulated with each other gents with mounting areas and with nodes for adjusting their relative position, each of which contains a bracket with a through figured groove in which a L-shaped bracket with scales is mounted with the possibility of movement and fixing, while the mounting platform is mounted on a L-shaped bracket, the upper base made in the form of a figured plate with threaded rods installed in it with mounting pads at the ends and scales with arrow pointers for moving the rods along its axis, each simulator is temporally the mandibular joint is made in the form of a slider mounted on the main bracket with a screw lock, a disk with an arcuate groove and a straight groove directed at an angle relative to the vertical axis of the strut and spring stop, while the slider is mounted on the axis of the disk with the possibility of rotation and fixing, and the disk connected to the lower base with the help of the adjusting fur ^{5 of the} lower body, made in the form of a fork mounted in a cylindrical shank with the help of a spring-loaded spherical head installed in a rectilinear groove of the disk, two plates, one of which has a T-shaped through groove with scales, the plates are mounted in the T-groove with the ability to move relative to one another and fix, while at the end of one of the plates a cylindrical hinge is made connecting the adjustment mechanism with a lower base. 2. A device for adjusting the installation of the models of the upper and lower jaws in the central occlusion position, containing a U-shaped frame with a slider on which a spoon is fixed for placing the impression mass, characterized in that, in order to increase accuracy, mechanisms for linear and its angular movement and signals to indicate this movement, on the sides of the U-shaped frame are installed with the ability to move, change the length and fixation of the pointed probes oriented inward of the U-shaped frame, at the ends of the cat swarm is arranged to adjust the length of the probes ₃₀ with rounded ends for installation in the simulator of the temporomandibular joint.
