A multi-directional bite force measurement device based on force sensor

Abstract

The invention discloses a multi-direction biting force measuring device based on a force sensor. The multi-direction biting force measuring device comprises a detachable outer shell and a plurality of groups of measuring systems arranged in the outer shell, wherein the outer shell comprises an upper shell body and a lower shell body, the plurality of groups of measuring systems comprise a main measuring system with one end connected to the inner wall of the outer shell and the other end pushing against the inner wall of the outer shell, and an auxiliary measuring system with one end connected to the main measuring system and the other end connected to the inner wall of the upper shell body or the inner wall of the lower shell body. The multi-direction biting force measuring device based on the force sensor overcomes the defect that an existing instrument cannot measure the specific direction of the biting force, the real-time positive pressure is measured on the basis of pressure sensors of the measuring systems in four directions, the real-time measurement for the magnitude and direction of the biting force when a pair of upper and lower teeth chews an object can be realized, the multi-direction biting force measuring device can be used for diagnosis and treatment for oral diseases, the biting force measuring device provided by the invention can be repeatedly used, and the spherical outer shell can also provide a true chewing feeling when biting force of a person is measured.

Description

technical field [0001] The invention relates to a measuring device, in particular to a bite force measuring device. Background technique [0002] Occlusal force is an important index reflecting the size of masticatory function, and the maintenance of normal tissue structure and function of periodontal tissue depends on normal occlusal force. Bite force is related to the diagnosis and treatment of many diseases in the oral cavity, and it is widely used as an evaluation index for the recovery of masticatory function after surgery. When chewing food, the teeth, especially the molars, not only exert pressure on the food, but also have a tangential force on the food grinding. [0003] At present, the widely used device for measuring bite force on the market is the T-Scan bite analyzer, which uses a very thin induction sheet to measure the change of bite force over time. The most important sensor is a consumable and cannot be used for multiple measurements. The cost of large cro...

AI Technical Summary

Problems solved by technology

The most important sensor is a consumable and cannot be used for multiple measurements. The cost of large crowd measurement is high. The measured force is only the positive pressure of the plane where the sensor is located, and the direction and magnitude of the actual bite force cannot be measured. Changes over time, and the bitten object is only a thin sensory piece, without the solid feeling of chewing food

Occlusal analyzer is applied to the entire dentition, and the occlusal direction of a single pair of teeth cannot be clearly given
