[0002] A denture articulator is a dental tool that is used to simulate the upper and lower jaws and temporomandibular joints of the human body, thereby fixing the upper and lower jaw models and the articulator, and simulating the movement of the mandible to a certain extent. It can fix the patient's model to the articulator and transfer the patient's upper and lower jaw height and jaw position relationship to the articulator. It can also use the face bow to transfer the inherent position relationship of the patient's maxilla to the temporomandibular joint to the articulator and keep it stable, so that denture production processes such as tooth arrangement, waxing, wax model making, and bite adjustment can be carried out outside the mouth.

The main body includes a mounting seat, a rotating shaft, and an upper articulator. Rotating shafts are provided on both sides of the mounting seat, and the rotating shafts are engaged with the top front end of the support seat. This solution enables the bite plate to move vertically downward to achieve the effect of the upper and lower jaws biting together, avoiding sticking through a large amount of wax water, which affects the efficiency of denture processing.

[0004] The above solution still has some shortcomings. Although it can adjust the distance between the bite plate and the lower bite plate of the upper articulator to reduce the use of wax water, in actual use, after the articulator is used, a large amount of plaster, wax, grease, plastic particles and other stains are easily attached to the upper and lower bite plates. However, the current articulator is not convenient for separately disassembling and assembling the upper and lower bite plates. Since the overall shape of the articulator is irregular and the distance between the upper and lower bite plates is small, it is inconvenient for staff to clean and maintain the upper and lower bite plates of the articulator.

[0028] Reference Figures 1-6 An embodiment of the utility model provides a denture articulator, comprising a bracket 1 with a cavity provided therein, an adjustment plate 2 connected to the bracket 1 via a rotating shaft 3, and further comprising: a lower bite plate 5 and an upper bite plate 6, both of which are respectively connected to the bracket 1 and the adjustment plate 2 via mounting parts, wherein the top surface of the lower bite plate 5 faces the bottom surface of the upper bite plate 6; an adjustment portion arranged in the cavity of the bracket 1, wherein the adjustment portion is used to drive the lower bite plate 5 to move up and down.

[0029] Specifically, during use, the setting of the mounting parts can facilitate the separate disassembly and assembly of the lower bite plate 5 and the upper bite plate 6, and the disassembly and assembly operation is quick and convenient, thereby facilitating the cleaning and maintenance of the lower bite plate 5 and the upper bite plate 6 by the staff, and the setting of the adjustment part can facilitate the adjustment of the distance between the lower bite plate 5 and the upper bite plate 6, thereby meeting the fixation requirements of upper and lower jaw models of different sizes and the effect of biting together.

[0030] The adjusting part includes a screw 10 rotatably connected to the cavity of the bracket 1, a rotating rod 11 is rotatably connected to the bracket 1, one end of the rotating rod 11 and the surface of the screw 10 are fixedly connected with a bevel gear 12 that meshes with each other, and a slider 13 is slidably installed on the bracket 1, and the slider 13 is threadedly connected to the screw 10.

[0031] Specifically, when in use, by rotating the rotating rod 11 and driving the bevel gear 12 and the screw 10 to rotate, the slider 13 will drive the lower bite plate 5 to move up and down under the action of the thread, which can facilitate the adjustment of the distance between the lower bite plate 5 and the upper bite plate 6, thereby meeting the fixation requirements of upper and lower jaw models of different sizes and the effect of occlusion, thereby improving the applicability of the articulator.

[0032] The bracket 1 is provided with a slide groove 41 which is in communication with the interior of the bracket 1 , and the slider 13 is longitudinally slidably connected in the slide groove 41 .

[0033] Specifically, by providing the sliding groove 41 , the slider 13 can be guided so that the slider 13 can only slide longitudinally.

[0034] The mounting parts include: two shells 4, which are respectively fixedly connected to the adjustment plate 2 and the slider 13, wherein two moving blocks 8 are slidably connected in the shell 4, a spring 81 is fixedly installed between the two moving blocks 8, and an inclined block 82 is fixedly connected to the two moving blocks 8, and a pressing mechanism is provided on the shell 4; two pairs of mounting blocks 83, which are respectively plugged into the two shells 4, wherein a card slot 84 is provided on the mounting block 83, when the mounting block 83 is inserted into the shell 4, the inclined block 82 will be inserted into the card slot 84 by the elastic force of the spring 81, and the lower bite plate 5 and the upper bite plate 6 are respectively fixedly connected to the two pairs of mounting blocks 83.

[0035] Specifically, during use, when the lower bite plate 5 and the upper bite plate 6 need to be installed, the mounting blocks 83 on the lower bite plate 5 and the upper bite plate 6 can be respectively inserted into the two housings 4, so that the mounting blocks 83 squeeze the inclined surfaces of the inclined blocks 82.
