Bite force measurement method based on computer aid

Abstract

The invention discloses a bite force measurement method based on computer aid. The method includes the following steps that firstly, a bite force measurement instrument is connected with a computer, and the computer has an analyzing system and a display system; secondly, a user puts his / her strength to bite a bite mold of the bite force measurement instrument many times within the time of t; thirdly, the analyzing system of the computer draws bite force data within the time of t, and the data include the extreme value, the increasing and attenuating speed and the average bite force of bite force within the time of t; fourthly, the bite force data in the third step are displayed on the display system of the computer.

Description

technical field [0001] The invention belongs to a biomedical mechanics measuring device and relates to a measuring method related to human occlusal function. Background technique [0002] Bite force, also known as chewing pressure, reflects the static pressure that actually occurs during the closing of the lower teeth. It is generated from the muscle force that the mandibular elevating muscles pull the mandible and make the mandibular tooth group resist the maxillary tooth group. The occlusal force is the result of the synergistic effect between different units of the masticatory system (muscle, bone and teeth, etc.), which can reflect the mechanical tolerance of periodontal tissue and help us understand the relationship between teeth, periodontium, and masticatory muscles. It can also evaluate the effect of oral restoration, periodontal treatment and orthodontic treatment. [0003] Diseases of the stomatognathic system, such as temporomandibular joint disorders and severe...

Problems solved by technology

However, the current research on occlusal force measurement started relatively late. In the existing system, the data is extremely single (most of them are only expressed by the maximum occlusal force value), and there is still a lack of systematic and complete measurement methods.

The measurement and related indicators of traditional instruments cannot judge pathological manifestations such as difficulty in maintaining bite force and premature decline of bite force, let alone analyze the mechanical characteristics of masticatory muscles systematically and comprehensively.

[0004] The utility model patent (201420830767.2) has solved the problem of converting mechanical signals into electrical signals, but this utility model only uses the terminal to display the maximum value and real-time change value

In the actual measurement process, we found that the bite force of most subjects is difficult to maintain stability, and the terminal value of the display changes extremely fast, making it difficult to count

Especially when it is required to "bite hard", the value rise and attenuation changes are difficult to grasp

When recording with the maximum value, it is not comprehensive to summarize the entire occlusal process with only one maximum measurement data
