Description

Technical Field

[0001] The utility model relates to the technical field of oral dental measuring instruments, in particular to a dental arch measuring device. Background Art

[0002] Arch measurement is the process of measuring and evaluating the teeth in the human mouth. By measuring the position, size, shape and relationship of the teeth, information about the bite, dentition alignment, jaw development, etc. can be obtained.

[0003] For example, a Chinese invention patent (CN115429473A) discloses a dental arch measuring device, which states: "The dental arch measuring device of the present invention is placed in the oral cavity of a child whose dental arch parameters need to be measured, and the width measuring rod is pulled to fix the retaining ring to the teeth on both sides of the dental arch of the child, and the push rod is pulled and rotated to extend or retract the length measuring ruler relative to the fixing part and rotate the length measuring ruler so that the tip of the length measuring ruler contacts the tooth midline or the incisor mastoid, and the locking part is twisted to contact the inner wall of the fixing part. The current position of the fixed length measurement is measured, and the relative position of the scale on the length measuring ruler and the angle measuring disk is used to conveniently read the current angle to complete the measurement of the child's dental arch length. The dental arch measurement device is simple to operate, easy to use, efficient and time-saving, and has low cost. It is highly accepted by children and their parents." It also records: "Model measurement and analysis, each time the child visits the doctor, an intraoral impression must be taken first, and the model is then measured after it is infused. The intraoral impression process is relatively uncomfortable and the child is not easy to cooperate. The whole process is complicated, poorly adaptable, and time-consuming." Technical problems.

[0004] To sum up the above, this method has the following technical problems: when the device measures the rear end of the dental arch, the measuring ruler needs to be opened.

[0038] The extension support mechanism 3 includes an annular groove 6, a torsion spring 7, a rotating collar 8, an oral arc bracket 9, a clamping groove 10, a toggle assembly and a clamping assembly. The surface of the connecting rod 1 is provided with an annular groove 6, and the surface of the annular groove 6 is rotatably connected with the rotating collar 8. The middle parts of the annular groove 6 and the rotating collar 8 are respectively fixedly connected to the two ends of the torsion spring 7. The outer surface of the rotating collar 8 is fixedly connected with the oral arc bracket 9, and the middle part of the oral arc bracket 9 is provided with a clamping groove 10.

[0039] The fixed support mechanism 4 includes a fixed ring 18, an oral arc bracket 19 and a clamping groove 20. The middle part of the ring groove 6 is fixedly connected with the fixed ring 18. The fixed ring 18 is connected to the side of the oral arc bracket 19 away from the torsion spring 7. The outer surface of the fixed ring 18 is fixedly connected with the oral arc bracket 19. The middle part of the oral arc bracket 19 is provided with a clamping groove 20. The oral arc bracket 19 and the oral arc bracket 19 can form a U-shaped frame when they are unfolded in parallel. The formed U-shaped frame can support the inner wall of the oral cavity so that the upper and lower dental arches are located on the upper and lower sides of the rubbing pad 5.

[0040] Specifically, the toggle assembly includes a screw ring 11, a connecting piece 12 and a linkage rod 13. The surface of the connecting rod 1 is rotatably connected to the screw ring 11, the outer surface of the screw ring 11 is fixedly connected to the connecting piece 12, and the middle part of the connecting piece 12 is fixedly connected to the linkage rod 13. By installing the screw ring 11, the oral arc bracket 9 can be flipped and contracted by rotating the screw ring 11.

[0042] Through the above structural design, it can be known that by rotating the screwing ring 11, the screwing ring 11 rotates with the connecting rod 1 as the axis, and the screwing ring 11 drives the oral arc bracket 1 9 to flip toward the side of the oral arc bracket 2 19 through the connecting piece 12 and the linkage rod 13. When the oral arc bracket 1 9 flips, it drives the rotating ring 8 to rotate on the surface of the ring groove 6. When the rotating ring 8 rotates, the torsion spring 7 accumulates elastic potential energy. When the oral arc bracket 1 9 flips, it cooperates with the oral arc bracket 2 19 to fold the rubbing pad 5. After completion, the contracted device is placed into the interior of the oral cavity, and the oral arc bracket 2 19 is pressed against the Hold one side of the inner wall of the oral cavity, loosen the screw ring 11, and the torsion spring 7 releases its elastic potential energy. The torsion spring 7 is reset and drives the rotating ring 8 to rotate. At the same time, the oral arc bracket 9 turns over with the rotating ring 8. The oral arc bracket 19 turns over 180 degrees and is parallel to the oral arc bracket 2 19. At the same time, the rubbing pad 5 is fully unfolded. The oral arc bracket 1 9 and the oral arc bracket 2 19 support the inner wall of the oral cavity on both sides. After completion, the patient only needs to bite the rubbing pad 5. After completion, the rotating ring 8 is rotated to make the oral arc bracket 1 9 turn over and shrink, and the entire device can be taken out from the oral cavity. Example 2

[0043] The dental arch measurement device provided in Example 1 is further optimized. Specifically, Figure 5-Figure 6As shown, the clamping assembly includes a lifting rod 14, a limit block 15, an extrusion plate 16 and an elastic spring 17, wherein the middle part of the oral arc bracket 9 is slidably connected with the lifting rod 14, wherein the top end of the lifting rod 14 extends to the outside of the oral arc bracket 9 or the clamping groove 20, and the top end of the lifting rod 14 is fixedly connected with the limit block 15, wherein the limit block 15 is in contact with the outer side wall of the clamping groove 10 or the clamping groove 20; wherein one end of the lifting rod 14 away from the limit block 15 is fixedly connected with the extrusion plate 16, and the lifting rod 14 is sleeved with an elastic spring 17, one end of the elastic spring 17 is fixedly connected to the top surface of the inner wall of the clamping groove 10 or the clamping groove 20, and the other end of the elastic spring 17 is fixedly connected to the extrusion plate 16, and the rubbing pad 5 is pressed tightly in the clamping groove 10 or the clamping groove 20 through the extrusion plate 16.

[0044] Specifically, the number of the clamping components is more than two groups, and the clamping components are symmetrically arranged on the oral arc bracket 1 9 and the oral arc bracket 2 19; wherein the rubbing pad 5 is arranged between the oral arc bracket 1 9 and the oral arc bracket 2 19 through the clamping components.

[0045] Specifically, the rubbing pad 5 is made of a rubber film, and a storage cavity 21 is opened in the middle of the rubbing pad 5 .

[0046] Through the above structural design, after the device is used, the limit block 15 on the oral arc bracket 9 is pulled up to move the lifting rod 14 upward, and the movement of the lifting rod 14 drives the extrusion plate 16 to move upward. After the extrusion plate 16 moves upward, it stops limiting the rubbing pad 5, and then one side of the rubbing pad 5 can be taken out from the clamping groove 10, and the other side of the rubbing pad 5 can be taken out from the oral arc bracket 2 19 by repeating the operation. After the rubbing pad 5 is taken out, the air-dried clay in the storage cavity 21 can be taken out to obtain the specific size of the dental arch.
