[0002] Articulatory paper is a diagnostic tool used to assess the bite relationship of the teeth. It is usually a thin, soft paper with high color stability. The use of articulatory paper is very simple. The patient bites on the articulatory paper and then moves the jaw to produce jaw joint movement during the bite. The color of the articulatory paper will be impressed by the contact between the teeth, thus showing the patient's bite relationship.

[0003] Clinically, the occlusal effect of complete dentures is usually checked using articulating paper, and then the occlusal surface is adjusted according to the staining. Currently, articulating paper is usually held in the mouth by tweezers or forceps for patients to bite.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] The inventor has found that in clinical practice, the occlusal effect of full dentures is usually checked using bite paper, and then the occlusal surface is adjusted according to the staining. At present, bite paper is usually held by tweezers or forceps and placed in the oral cavity for patients to chew. The bite paper is often deformed due to loose fixation, which affects the adjustment effect. When doctors use oral chewing bite paper, they usually clamp it with tweezers and insert it into the patient's mouth. When treating the teeth inside the oral cavity, it is difficult to insert the oral chewing bite paper, which increases the difficulty of treatment. Nowadays, there is also a disposable oral chewing bite paper with a clamping tool. Although this device is easy to use, the disposable oral chewing bite paper fixing device increases the equipment cost and requires multiple replacement of the bite paper, which brings great inconvenience to medical work.

[0031] Based on the above findings, the present application provides a replaceable chewing paper holder, comprising a handle 1 and arc-shaped arms 2 slidably connected to both sides of the handle 1, wherein the handle 1 is a hollow structure and a spacing adjustment mechanism 3 is provided in the cavity, wherein the spacing adjustment mechanism 3 cooperates with the arc-shaped arms 2, and a paper discharge mechanism 4 and a pulling mechanism 5 are fixedly provided on the two arc-shaped arms 2, wherein the pulling mechanism 5 cooperates with the paper discharge mechanism 4 to realize paper taking.

[0034] Manually rotate the turbine A31, and through the cooperation between the turbine A31 and the turbine B32, the turbine A31 drives the turbine B32 to rotate, and the rotation of the turbine B32 drives the gear 33 arranged on both sides of the turbine B32 to rotate, and the gear 33 is engaged with the rack 21 arranged at the bottom of the arc arm 2, so that the arc arm 2 arranged on both sides of the handle 1 moves in different directions respectively, and finally the expansion range of the arc arm 2 is adjusted to adapt to the oral size of different patients.

[0037] During specific use, different types of chewing papers are respectively rolled onto the reel 43 in the paper output box 42, and the head end of the chewing paper is clamped by the fixed plate 44 and extends between the movable plates 45. Different types of chewing papers can be used by manually rotating the paper output box 42, and the purpose of transferring the chewing paper clamped by the movable plate 45 forward can be achieved by the electric push plate 46 provided on the fixed plate 44.

[0038] Furthermore, the pulling mechanism 5 includes a fixed rod 51 fixedly connected to the arc arm 2 and a motor 53, the end of the fixed rod 51 is rotatably connected to the rotating rod 52, the output end of the motor 53 is connected to the rotating shaft 41, the rotating shaft 41 is connected to a connecting rod 54, the connecting rod 54 is rotatably connected to the rotating rod 52, and the end of the connecting rod 54 is connected to a connecting plate 55.

[0040] Based on Example 1, refer to Fig. 9As shown, in order to facilitate the storage and placement of the articulating paper holder, a placement rack 7 specifically used for placing the articulating paper holder is provided. By providing an electric telescopic rod 6 at the end of the arc-shaped arm 2, the electric telescopic rod 6 cooperates with the placement rack 7 to achieve storage and placement, thereby avoiding the technical problem of the articulating paper holder tipping over and being damaged.

[0041] Specific application cases: The bite height needs to be determined during the production process of full dentures to better maintain oral health. If the height of the denture is too high, it may increase tension and cause local discomfort. If the height is too low, it may also cause a weak bite. Therefore, when making full dentures, the bite height must be measured to enable patients to chew food better.

[0042] Full dentures mainly consist of artificial teeth and bases. The height of dentures varies from patient to patient, so each patient must choose the right height for bite. After the base of the denture fits tightly with the mandibular tissue to generate adsorption force, the denture will be adsorbed on the alveolar ridge, allowing the patient to restore normal chewing function. Therefore, it is relatively important to measure the bite height of the denture.

[0043] The articulation paper method is a commonly used method for checking the occlusal relationship. In this method, the doctor places the articulation paper between the upper and lower teeth and asks the patient to bite down with force. When the patient bites down, the contact between the teeth will leave marks on the articulation paper. By observing these marks, the doctor can analyze the contact relationship and position of the teeth, thereby evaluating the accuracy and stability of the occlusal relationship.

[0044] The present application provides a chewing paper clamp for replaceable chewing paper. During specific use, different types of chewing paper are rolled onto a reel 43 in a paper output box 42, and the head end of the chewing paper extends outside a movable plate 45, and the chewing paper is clamped and fixed by the movable plate 45.

[0045] Furthermore, the expansion degree of the arc arm 2 is adjusted according to the size of the patient's mouth. Specifically, the turbine A31 is manually rotated, and the turbine A31 cooperates with the turbine B32 to achieve that the turbine A31 drives the turbine B32 to rotate, and the rotation of the turbine B32 drives the gear 33 arranged on both sides of the turbine B32 to rotate, and the gear 33 is engaged with the rack 21 arranged at the bottom of the arc arm 2, so that the arc arm 2 arranged on both sides of the handle 1 moves in different directions respectively, and finally the expansion range of the arc arm 2 is adjusted to adapt to the oral size of different patients.

[0046] Furthermore, the required type of articulating paper is selected, and the paper output box 42 is manually rotated so that the required articulating paper is close to the inner side of the arc-shaped arm 2 .

[0047] Furthermore, by starting the motor 53 to drive the connecting rod 54 to rotate, the connecting plate 55 at the head end of the connecting rod 54 is brought close to the movable plate 45, and then the movable plate 45 is pushed to a position connected to the connecting plate 55 by the electric push plate 46, and then the head end of the bite paper is pasted to the pasting surface of the connecting plate 65, thereby achieving the pasting and fixation of the bite paper.

[0048] The connecting rod 54 is further rotated so that the connecting plates 55 respectively connected to the connecting rods 54 at both ends are connected to each other through the magnetic attraction layer on the outer side of the connecting plate 55, so that the articulating paper is stretched into an arc shape to match the structural arrangement of the teeth, thereby facilitating the occlusal test of the articulating paper.

[0049] After the test is completed, the electric telescopic rod 6 provided at the end of the arc-shaped arm 2 is inserted into the placement rack 7 to realize the storage and placement of the bite paper holder.

[0050] It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
