Device and method for displaying dental occlusion stress distribution

Abstract

The invention relates to the technical field of medical experimental apparatuses, and concretely discloses a device and a method for displaying dental occlusion stress distribution. The device comprises a box body, polarized light sources, a polarizer, a glass plate, a polarization analyzer, a two-dimensional dental model, a sliding mechanism and a pressing mechanism, the polarized light sources are arranged at the lower part of the box body, the polarizer is arranged at the middle part of the box body and is arranged horizontally, the glass plate is arranged at the upper end of the box body and is arranged horizontally, the two-dimensional dental model is placed on the glass plate, two ends of the two-dimensional dental model are connected with the box body through the sliding mechanism,an upper tooth model and a lower tooth model of the two-dimensional dental model move in a horizontal opposite-occlusion manner by the sliding mechanism, the polarization analyzer is placed on the two-dimensional dental model, the pressing mechanism is arranged at the upper end of the box body, and the pressing mechanism is used for pressing the of the polarization analyzer on the two-dimensionaldental model. The device and the method have the advantages of realization of visual and clear displaying of the stress distribution during dental occlusion, simplicity in operation, and great improvement of the accuracy.

Description

technical field [0001] The invention relates to the technical field of medical experiment equipment, in particular to a device and method for displaying tooth occlusal stress distribution. Background technique [0002] At present, most hospitals still judge the stress of patients' teeth based on the doctor's experience. When performing orthodontics or installing dentures in the hospital, occlusal papers are usually used to show the occlusal relationship of the tooth surfaces. The patient needs to bite the occlusal paper with his teeth, so that the colorant on the occlusal paper adheres to the surface of the patient's teeth. By observing the depth of the color attached to the surface of the patient's teeth, the doctor can then judge the contact and force of the patient's teeth in the occlusal state. [0003] In addition, there is an electronic inspection and analysis system for occlusion. The sensor film of the system has a horseshoe-shaped sensing area, which is composed o...

AI Technical Summary

Problems solved by technology

Based on incomplete information, doctors cannot consider all possible situations, so problems such as misdiagnosis or inappropriate treatment may occur

However, although the accuracy of the existing electronic examination and analysis system for occlusion has been improved, the system is relatively complicated and expensive, and cannot be widely used in conventional hospitals.
