Description

Technical Field

[0001] The utility model relates to the field of artificial tooth articulators, in particular to an artificial tooth articulator. Background Art

[0002] Denture articulators are devices used to simulate the jaw and jaw articulation mechanism in order to analyze and diagnose dental problems and to manufacture various devices and dentures according to the patient's specific occlusal conditions. Upper and lower frame components are usually used to simulate the upper and lower jaws of a person.

[0003] Doctors usually use a denture articulator to analyze and diagnose the patient's teeth. However, when a conventional denture articulator is used, the dental mold is usually fixed on the denture articulator or the dental mold is detachably installed on the denture articulator. Regardless of whether it is a fixed dental mold or a detachable dental mold, the upper and lower jaws are generally set relatively flush, but the conditions of patients are different. Some patients have overbite (the distance of the upper and lower overlapping front teeth). Normal overbite should not exceed 1 / 3 of the lower incisor, but some patients' teeth exceed this distance. Some patients have crossbite, that is, the lower incisor exceeds the upper teeth by a certain distance, and the front teeth cannot cover the lower incisor. The existing denture articulator cannot simulate this situation well, which greatly reduces the doctor's analysis and explanation and the patient's recognition. It has poor applicability and cannot meet the needs of actual use.

[0004] Therefore, it is necessary to provide a denture articulator to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0033] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0034] Example 1

[0035] See also Figures 1 to 8 A denture articulator comprises a mandibular frame 1 and a maxillary frame 2, wherein the maxillary frame 2 is rotatably mounted on the mandibular frame 1 via a first connecting shaft 3, and further comprises:

[0036] The dental model mounting mechanism can be detachably mounted on the adjustment plate 12, and the adjustment plate 12 can be adjusted and mounted on the mandibular frame 1 and the maxillary frame 2;

[0037] The dental model adjustment mechanism is installed at the connection between the adjustment plate 12 and the mandibular frame 1 and the maxillary frame 2, wherein the dental model adjustment mechanism includes:

[0038] A rotating handle 28 is used to linearly adjust the dental mold 4 on the adjustment plate 12, and the rotating handle 28 is rotatably and telescopically mounted on the mounting box 32, and the mounting box 32 is fixedly mounted on the mandibular frame 1 and the maxillary frame 2; and

[0039] The adjusting rod 24 and the rotating cylinder 21 , the rotating handle 28 is fixedly installed at one end of the adjusting rod 24 , and the adjusting rod 24 is telescopically and rotatably installed inside the rotating cylinder 21 .

[0040] Furthermore, a plurality of first driving blocks 23 are fixedly connected to the interior of the rotating cylinder 21, and a plurality of second driving blocks 25 for adapting to the sliding connection with the first driving blocks 23 and driving the rotating cylinder 21 to rotate are provided on the adjusting rod 24, and a blocking plate 26 for telescopic limiting is fixedly connected to the adjusting rod 24, and the adjusting rod 24 and the rotating cylinder 21 are movably mounted inside the mandibular frame 1 and the maxillary frame 2 through the mounting frame 22.

[0041] Further, the dental model adjustment mechanism also includes a first screw rod 15 for driving the dental model 4 to perform a first linear movement, the adjustment plate 12 is slidably connected to the mandibular frame 1 and the maxillary frame 2 through a slider plate 14, and the slider plate 14 is slidably connected to the first slide rod 16, the slider plate 14 is threadedly connected to the first screw rod 15, and the slider plate 14 is slidably connected to the moving plate 17 through a slider limiter

[0042] Furthermore, the dental model adjustment mechanism also includes a second connecting shaft 30 for driving the first screw rod 15 to rotate. One end of the first screw rod 15 is rotatably connected to the second connecting shaft 30 through a bevel gear pair 29. The second connecting shaft 30 is rotatably connected to the inside of the mandibular frame 1 and the maxillary frame 2. A second gear 31 is fixedly connected to the second connecting shaft 30, and the second gear 31 is meshed with the first gear 27. The first gear 27 is fixedly mounted on the adjustment rod 24.

[0043] Furthermore, the dental model adjustment mechanism also includes a second screw rod 19 for driving the dental model 4 to perform a second linear adjustment. The movable plate 17 is threadedly connected to the second screw rod 19, and the movable plate 17 is slidingly connected to the interior of the mandibular frame 1 and the maxillary frame 2 through a second sliding rod 18. The second screw rod 19 is rotatably connected to the rotating cylinder 21 through a synchronous belt 20.

[0044] Preferably, according to the occlusion of different patients' teeth, the handle 28 can be rotated to make corresponding adjustments. In the normal use state, the dental molds 4 on the mandibular frame 1 and the maxillary frame 2 are in a combined and symmetrical position.

[0045] When the patient's teeth are overbite or underbite, it is only necessary to adjust the rotating handle 28 to drive the adjusting rod 24 to rotate. At this time, the first gear 27 and the second gear 31 are in a meshing position. In addition, the second driving block 25 on the corresponding adjusting rod 24 is not in contact with the first driving block 23 inside the rotating cylinder 21. At this time, the rotation of the adjusting rod 24 will not drive the rotating cylinder 21 to rotate. Figure 6 As shown;

[0046] Synchronously, the second connecting shaft 30 on the second gear 31 is driven to rotate under the rotation relationship of the first gear 27 on the adjusting rod 24, and the first screw 15 is driven to rotate under the driving relationship of the bevel gear pair 29. At this time, the adjusting plate 12 moves under the guidance of the first slide bar 16, thereby realizing the adjustment and movement of the dental model 4, so as to simulate the overbite or underbite of the teeth. It has strong adjustability, further improves the doctor's analysis and explanation level, and is more convenient for patients to understand.

[0047] When the patient's teeth are in an extreme situation of left-right deviation in the bite, the rotating handle 28 is pulled to drive the adjustment rod 24 to move outward. When the first gear 27 and the second gear 31 are completely separated, the second driving block 25 on the adjustment rod 24 just contacts the first driving block 23 inside the rotating cylinder 21. When the adjustment rod 24 is driven to move outward, under the adaptive guiding relationship between the first driving block 23 and the second driving block 25, the second driving block 25 on the adjustment rod 24 is at a position intersecting with the first driving block 23, and can be limited accordingly by the blocking plate 26 on the adjustment rod 24.

[0048] Correspondingly, when the rotating handle 28 is turned to drive the adjusting rod 24 to rotate, since the first gear 27 and the second gear 31 are in a state of being far away from each other, the rotation of the adjusting rod 24 will not drive the second connecting shaft 30 to rotate, but will only drive the rotating cylinder 21 to rotate. At this time, the rotating cylinder 21 drives the second screw 19 to rotate under the driving action of the synchronous belt 20. At this time, under the guidance of the second sliding rod 18, the dental mold 4 can be driven to move left and right for adjustment, so as to simulate the situation of left and right deviation of the patient's teeth in extreme cases. It has high adjustability and is easy to use.

[0049] It should be particularly noted that both the rotating cylinder 21 and the second screw rod 19 are provided with pulleys which are synchronously connected with the synchronous belt 20 .

[0050] Example 2

[0051] like Figure 1 to Figure 3 As shown, in this embodiment, based on embodiment 1, the dental model mounting mechanism includes a gypsum base 5 and a cylindrical magnet 11, the cylindrical magnet 11 is fixedly mounted below the gypsum base 5, a magnetic suction cavity 13 which is magnetically connected to the cylindrical magnet 11 is provided on the adjustment plate 12, and the dental model 4 is arranged on the gypsum base 5.

[0052] Furthermore, the dental model mounting mechanism also includes a limit plate 9 for limiting the installation of the gypsum base 5. The gypsum base 5 is provided with a limit groove 6 which is adapted to be connected to the limit plate 9. A pull plate 8 is fixedly connected to one end of the limit plate 9, and the limit plate 9 is slidably connected to the metal mounting plate 7. In addition, a magnet 10 for magnetic connection with the metal mounting plate 7 is provided on the side of the pull plate 8 close to the limit, and the metal mounting plate 7 is fixedly connected to the adjustment plate 12.

[0053] Preferably, in this embodiment, when the dental model 4 needs to be replaced, the pull plate 8 is pulled to drive the limit plate 9 to move away from the limit groove 6. At this time, it is convenient to pull out the limit plate 9, so that the gypsum base 5 can be taken out from the magnetic suction cavity 13 on the adjustment plate 12, which is convenient for timely replacement of the dental model 4 for later maintenance and use.

[0054] It should be particularly noted that the components in this application are all universal standard parts or components well known to those skilled in the art, which effectively solve the technical problems raised in the background technology.
