Problems solved by technology

However, due to factors such as the narrow force space and high measurement accuracy requirements, there is currently no standardized method to perform performance tracking such as orthodontic force testing, occlusal force distribution, and effect persistence of the orthodontic appliance before the patient wears it.

Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027] see figure 1 , figure 2 and image 3 , the orthodontic force testing system for invisible aligners of the present invention includes a base 1, a simulated mandible to be corrected and anchored teeth 2, a plurality of sensor supports 3, a plurality of multidimensional force sensors 4, a plurality of force transmission links 5, a plurality of A connecting piece 6, a pair of support rods 7, a simulated skull 8, simulated maxillary teeth 9, a multi-channel signal transmitter 10, a multi-channel signal converter 11, and a signal display and processing device 12.

[0028] The base 1 is semicircular. The simulated mandibular corrected and anchored teeth are located at the center of the base 1 .

[0029] Each sensor support 3 is fixed on the edge of the base 1 in an annular array, and corresponds to each tooth of the artificial mandibular to be corrected and supported b...

Abstract

The invention discloses a correction force test system for a stealth appliance. The correction force test system for the stealth appliance comprises a semi-circular base, simulation jaw correction and anchorage teeth, multiple sensor supports fixed at an edge of the base in an annular array mode, multiple multi-dimension force sensors attached to inner sides of the multiple sensor supports, multiple force transmission connection rods which are respectively connected with the simulation jaw correction and anchorage teeth and correspond to the multi-dimension force sensors, multiple connection members which are respectively connected and fixed with the force transmission connection rods and correspond to the multi-dimension force sensors and the sensor supports, a pair of supporting rods vertically fixed on the base, simulation head bones hinged with the top portion of the supporting rods, simulation jaw teeth fixed with the simulation head bones, a multi-channel signal transmitter, a multi-channel converter, and a signal display and processing device. The correction force test system is advantaged in that correction force and torque of the teeth under the action of the stealth appliance can be precisely measured, and a distribution force system of occlusal force is tested.

Description

technical field [0001] The invention relates to the field of testing the orthodontic force and occlusal force of an invisible appliance. Background technique [0002] Bracketless invisible aligners are new orthodontic products that rely on today's rapid development of 3D scanning technology, 3D printing technology, rapid thermoforming technology, and Internet visualization technology. It uses the deformation and displacement difference between it and the teeth to generate rebound correction force, and can realize tooth correction without steel wires and brackets, and has the advantages of beauty, comfort, convenience, cleanliness, and convenience. [0003] The orthodontic force is the initiating factor to achieve tooth movement. Only a reasonable force application position, force magnitude, and force distribution system can effectively achieve the correction of the target teeth. However, due to factors such as the narrow force space and high measurement accuracy requirement...
