Problems solved by technology

The most important induction sheet is a consumable and cannot be used for multiple measurements. The cost of large crowd measurement is high, and the bitten object is only a very thin induction sheet, which does not have the physical feeling when chewing food.
The most important thing is that the T-Scan occlusal analyzer is a medical instrument, which is expensive and has a narrow range of applications. It needs to go to a special medical research place and be operated by a special experimenter.

Embodiment

[0030] like Figure 1-6 As shown, a single tooth occlusal force measurement device based on a thin-film pressure sensor includes an upper measuring device 1, a lower measuring device 2 and a thin-film pressure sensor 3, and both the upper measuring device 1 and the lower measuring device 2 are made of renewable biodegradable materials For example, polylactic acid material (PLA) has good biodegradability and is often used in 3D printing materials. It has moderate hardness and gives people a certain chewing feeling when measuring. It is also non-toxic and can be repeatedly subjected to occlusal force with small deformation . The upper measuring device 1 is snapped into the groove of the lower measuring device 2, and the membrane pressure sensor 3 is installed between the round tables of the upper measuring device 1 and the lower measuring device 2, and the round tables of the upper measuring device 1 and the lower measuring device 2 are divided into upper round tables 7 and the...

Embodiment 2

[0034] The single tooth occlusal force measurement device based on the thin film pressure sensor of embodiment 1 is used for testing:

[0035] According to the size of the upper and lower teeth that the subject wants to measure (choose the left central incisor) and the relative position, select the corresponding type of occlusal platform, and assemble it to the measuring device, insert the thin film pressure sensor from the opening of the lower measuring device Insert it into the middle, cover the upper part, and put it into the corresponding upper and lower teeth. The subject bites the clamp lightly so that it does not slip from the two teeth. Figure 8 shown.

[0036] The thin-film pressure sensor can measure the pressure on a certain area. Use the measuring device to fix the thin-film pressure sensor and place it on the tooth to be measured in the oral cavity. The occlusal force is transmitted to the sensor by clamping the clamp and the corresponding data is obtained. The p...

Abstract

The invention discloses a measuring device for occlusal force of a single tooth based on a thin-film pressure sensor, comprising an upper measuring device, a lower measuring device and a thin-film pressure sensor, the upper measuring device snaps into a groove of the lower measuring device, and the thin-film The pressure sensor is installed between the round tables of the upper measuring device and the lower measuring device; the top occlusal table of the upper measuring device is in contact with the teeth of the upper dentition, and the bottom occlusal table of the lower measuring device is in contact with the teeth of the lower dentition. The device of the present invention can realize the real-time measurement of the occlusal force of the upper and lower pairs of teeth when occlusal, can be used for the diagnosis and treatment of oral diseases, and the device can be used repeatedly. chewing sensation.

Description

technical field [0001] The invention belongs to medical instruments, and relates to a medical 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. [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, which cannot be used for multiple measurements. The cost of measuring a large crowd is high, and the bitten object is only a very thin sensor, which does not have the p...
