[0029] The following is a method for using a mouth and maxillofacial temporomandibular joint rehabilitation training instrument.

[0030] First, pull the two mounting blocks 2 forward along the fixed blocks 1, the mounting blocks 2 drive the elastic clamping blocks 27 to pass through the multiple clamping groove structures 101 on the fixed blocks 1 in turn, let the mounting blocks 2 drive the upper dental tray 32 and the lower dental tray 42 to move forward, let the width of the front and back of the training instrument increase to be greater than the width of the front and back of the human head, then hang the connecting belt 11 on the back of the human neck, the two fixed blocks 1 are respectively attached to the cheeks of the human body through the silica gel pads 12, then pull the two mounting blocks 2 backward along the fixed blocks 1 synchronously, the mounting blocks 2 drive the elastic clamping blocks 27 to pass through the multiple clamping groove structures 101 on the fixed blocks 1 again, let the mounting blocks 2 drive the upper dental tray 32 and the lower dental tray 42 to move backward, until the upper dental tray 32 and the lower dental tray 42 are respectively aligned with the positions where the upper teeth and the lower teeth of the human body are located, at this time, the elastic clamping blocks 27 of the mounting blocks 2 are clamped and fixed in the corresponding clamping groove structures 101, finally, in the state that the mouth of the human body is half open, the upper dental tray 32 and the lower dental tray 42 are respectively sleeved in the middle of the upper teeth and the middle of the lower teeth, realize that the training instrument is firmly sleeved and fixed on the head of the human body by the connecting belt 11, the two fixed blocks 1, the two mounting blocks 2 and the upper dental tray 32, complete the wearing work of the training instrument.

[0031] After completing the wearing work of the training instrument, the two control motors 24 alternately drive the two winding wheels 23 to reciprocatingly wind and unwind the lower pull rope 41 connected thereto, when the control motor 24 on one side controls the winding wheel 23 to wind the lower pull rope 41 connected thereto, the longitudinal part of the lower pull rope 41 moves backward along the main pulley 22 and the auxiliary pulley 26, at the same time, the transverse part of the lower pull rope 41 moves away from the lower dental tray 42 along the main pulley 22, the lower dental tray 42 is pulled by the transverse part of the lower pull rope 41 to drive the lower teeth to move in the same direction, at the same time, the control motor 24 on the other side controls the winding wheel 23 to unwind the lower pull rope 41 connected thereto, let the transverse part of the lower pull rope 41 move with the lower dental tray 42 in the same direction, so as to realize that the lower teeth are driven to move in the left and right directions to one side under the program setting, conversely, the lower teeth can also be driven to move in the left and right directions to the other side under the program setting, repeat the above-mentioned action of driving the lower teeth to move left and right relative to the upper teeth, so as to realize the left and right movement training of the temporomandibular joint, and enhance the strength of the masticatory muscles around the temporomandibular joint and the stability of the temporomandibular joint.

[0032] The training instrument performs the specified reciprocating movement training action on the temporomandibular joint according to the program set by the therapist through electronic instruments and equipment, on the basis of ensuring the effectiveness of the training of the temporomandibular joint, reasonably controls the force to reduce the risk of joint damage.

[0033] Example 2, this example is based on Example 1 above, such as... Figures 1-6 As shown, each of the two fixed rods 21 has a movable slider 51 slidably connected to it; each of the two movable sliders 51 is fixedly connected to the corresponding fixed rod 21 with an internal compression spring 52, and the internal compression spring 52 is initially in a compressed state; each of the two movable sliders 51 has a pressure rod 53 fixedly connected to its lower end, and the front end of the pressure rod 53 is aligned with the corresponding lower pull rope 41 located in the transverse part between the lower dental brace 42 and the main pulley 22; the lower ends of the two movable sliders 51 are respectively fixedly connected to the corresponding lower pull rope 41 located in the longitudinal part between the main pulley 22 and the auxiliary pulley 26, allowing for left and right movement of the temporomandibular joint. During training, the movable slider 51 is restricted by the longitudinal part of the lower pull rope 41, preventing the compressed inner pressure spring 52 from pushing the movable slider 51 to drive the pressure rod 53 to press the lateral part of the lower pull rope 41 forward. Each of the two pressure rods 53 has a groove structure 530 at its front end, and the groove structure 530 of the pressure rod 53 is aligned with the corresponding lower pull rope 41. After the left and right movement training of the temporomandibular joint is completed, the two control motors 24 drive their connected winding wheels 23 to simultaneously release the two lower pull ropes 41 forward, while the compressed inner pressure spring 52 pushes the movable slider 51. Moving forward along the fixed rod 21, the movable slider 51 drives the pressure rod 53 to lock the lateral part of the lower pull rope 41 through the groove structure 530, preventing the lateral part of the lower pull rope 41 from detaching from the pressure rod 53. The inner pressure spring 52 continues to push the movable slider 51 to drive the pressure rod 53 forward. The pressure rod 53 pushes the locked lateral part of the lower pull rope 41 forward, and at the same time, the lateral part of the lower pull rope 41 drives the lower quick-release lever 411 and the lower dental brace 42 to stretch forward. The lower dental brace 42 drives the lower teeth to stretch forward. Then, the two control motors... 24 drives the connected winding wheel 23 to simultaneously wind the two lower pull ropes 41 backward. At the same time, the lower pull ropes 41 pull the movable slider 51, causing the inner pressure spring 52 to compress and reset backward. Simultaneously, the lateral part of the lower pull ropes 41 drives the lower quick-release lever 411 and the lower dental brace 42 to move and reset backward. The lower dental brace 42 drives the lower teeth to reset backward. The above-mentioned action of the lower teeth moving back and forth relative to the upper teeth is repeated to achieve the forward and backward movement training of the temporomandibular joint, expand the training range of temporomandibular joint movement, and enhance the training effect of temporomandibular joint movement.

[0034] Example 3, this example is based on Example 2 above, such as... Figures 1-8As shown, two lower clamping blocks 61 are detachably inserted on the lower dental brace 42; two upper clamping blocks 62 are detachably inserted on the upper dental brace 32, wherein the upper clamping blocks 62 are slidably connected to the upper dental brace 32 through a rod structure, and a layer of silica gel buffer structure is sleeved on the outer surface of the rod structure, which can avoid the rod structure of the upper clamping blocks 62 scratching the lips when reciprocally contacting the lips; the two upper clamping blocks 62 are respectively slidably connected to a corresponding lower clamping block 61; an outer compression spring 63 is fixed between each of the two upper clamping blocks 62 and the corresponding lower clamping block 61; after the left and right movement training and the front and back movement training of the temporomandibular joint are completed, the two lower pull ropes 41 are respectively detached from the corresponding main pulleys 22, and then the two lower clamping blocks 61 are clamped on the lower dental brace 42, and the two upper clamping blocks 62 are clamped on the upper dental brace 32; when the upper teeth and the lower teeth are close to each other, the upper dental brace 32 and the lower dental brace 42 jointly squeeze the two upper clamping blocks 62 and the two lower clamping blocks 61 close to each other, at this time, the outer compression spring 63 between the upper clamping blocks 62 and the lower clamping blocks 61 is in a compressed state, and the temporomandibular joint needs to exert force to overcome the reverse elastic force formed after the compression of the outer compression spring 63, so that the upper teeth and the lower teeth are in a close-together occlusion state; when the lower teeth move away from the upper teeth, the compressed outer compression spring 63 pushes the lower clamping block 61 to drive the lower dental brace 42 to move downward with the lower teeth, and the above-mentioned close-together and far-apart movements of the upper teeth and the lower teeth are repeated to realize the occlusion movement training of the temporomandibular joint, and further enhance the strength of the masticatory muscles around the temporomandibular joint and the stability of the temporomandibular joint; a elastic band 64 is commonly fixed between the two lower clamping blocks 61 and tightly abuts the inner side of the lower dental brace 42; a elastic band 64 is also commonly fixed between the two upper clamping blocks 62 and tightly abuts the inner side of the upper dental brace 32; the two lower clamping blocks 61 are fixed together through the elastic band 64, and the two upper clamping blocks 62 are also fixed together through the elastic band 64, so that the two lower clamping blocks 61, the two upper clamping blocks 62 and the two elastic bands 64 jointly form an integral whole tightly between the upper dental brace 32 and the lower dental brace 42, which improves the firmness of the lower clamping blocks 61 and the upper clamping blocks 62 fixed on the lower dental brace 42 and the upper dental brace 32 respectively, and avoids the loosening of the lower clamping blocks 61 and the upper clamping blocks 62 during the occlusion movement training of the temporomandibular joint.
