Adjustable condylar guide device

Abstract

The invention discloses an adjustable condylar guide device. The device comprises a condylar guide piece main body, left and right adjustable condylar guide pieces and a locking mechanism, wherein the condylar guide piece main body is fixed on an occluder; the left and right adjustable condylar guide pieces are symmetrically arranged on left and right sides of the condylar guide piece main body and can rotate in a vertical plane relative to the condylar guide piece main body; the locking mechanism can lock angles of the adjustable condylar guide pieces; the adjustable condylar guide pieces can be rotated by loosening the locking mechanism; the adjustable condylar guide pieces are rotated to make angles of condylar slots on the lower surfaces of the adjustable condylar guide pieces changed, so that a protrusive movement angle of a lower jaw is changed; and after the adjustable condylar guide pieces are rotated and adjusted to reach the required angle, the locking mechanism is locked tolock the angles of the adjustable condylar guide pieces. The adjustable condylar guide device is arranged on the occluder and can simulate an occlusion state and a jaw position relationship of an oral cavity under the condition that the effective protrusion angle of the lower jaw is in the range of 10 to 50 degrees, and an abnormal jaw joint state can be adjusted by the device to form a special occlusion state.

Description

technical field [0001] The invention relates to a component of an artificial headform articulator, in particular to a device capable of adjusting the condyle guide slope in the artificial headform articulator for teaching. Background technique [0002] The condyle guide slope refers to the forward extension condyle guide slope, which is the angle of the movement path of the condyles on both sides when the patient's mandible moves forward and downward. This angle is based on the standard plane. Some people in stomatology regard the plane connecting the nose wing-ear hole as the standard plane, which is called the nose wing-ear plane. This plane is the best when normal people stand and look forward. Close to the horizontal plane, the condyle guide slope is the angle between the condyle groove and the nose-ear plane. The imitation headform articulator used for general teaching has fixed condyle guide slope and cannot be adjusted. Generally, the average value of condyle guide s...

AI Technical Summary

Problems solved by technology

The imitation headform articulator used for general teaching has fixed condyle guide slope and cannot be adjusted. Generally, the average value of condyle guide slope is taken, and the occlusal device with fixed condyle guide slope is used to simulate the patient's oral occlusal state, so The specific condyle guide slope is not particularly consistent with the actual patient, so there is a certain gap between teaching simulation and clinical practice, and it is impossible for students to master the occlusal state and jaw position relationship under various condyle guide slopes during teaching.
