[0038] Example 1
[0039] like Figure 1 As shown, this embodiment provides a dental model fixing device for connecting a dental model 20 (upper dental model, lower dental model) to a jaw frame body 10, so that the dental model 20 is fixed in direction and height on the jaw frame body 10. Figure 1 、 Figure 2As shown, for the convenience of structural description, the side facing the dental model 20 is the front side, and the side facing the jaw frame body 10 is the back side. All components of this embodiment are structurally described based on this direction standard. Figure 1 、 Figure 2 、 Figure 3 As shown, the dental mold fixing device of this embodiment mainly includes: a transfer seat 100 and a model seat 200. The transfer seat 100 and the model seat 200 are detachably connected. The transfer seat 100 includes a jaw frame connecting portion 110 and a dental mold supporting portion 120. The dental mold supporting portion 120 is arranged on the front of the jaw frame connecting portion 110, and the back of the jaw frame connecting portion 110 is used for detachable connection to the jaw frame body 10. The dental mold supporting portion 120 is provided with a first magnetic component 130 to generate a magnetic force. The front of the model seat 200 is used to connect the dental model 20, and the back of the model seat 200 is used for detachable connection with the dental mold supporting portion 120. In the specific structure, a second magnetic component 230 is provided on the model seat 200, and the model seat 200 is connected to the dental mold supporting portion 120 through the magnetic connection between the second magnetic component 230 and the first magnetic component 130.
[0040] The dental model fixing device of this embodiment is configured by connecting the model base 200 to the dental model 20, providing a first magnetic member 130 on the model base 200, and providing a second magnetic member 230 on the transfer base 100. The model base 200 is connected to the dental model supporting portion 120 of the transfer base 100 by magnetic attraction between the second magnetic member 230 and the first magnetic member 130. The transfer base 100 is then detachably connected to the jaw frame body 10 by the jaw frame connecting portion 110. This completes the connection of the dental model 20 to the jaw frame body 10. The magnetic attraction of the model base 200 and the transfer base 100 replaces the original form of plaster fixation, thereby reducing the use of plaster. The use of this dental model fixing device is cleaner and more beautiful. The pre-generated model base 200 and transfer base 100 are used to fix the dental model 20, reducing manual operation procedures and time, and improving installation efficiency. The mating structure of the model base 200 and the transfer base 100 eliminates the problem of curing shrinkage, thus avoiding the displacement of the deformed model caused by using plaster. This improves the accuracy and pass rate of maxillary frame production, demonstrating its high-value practical application. This dental model fixture provides a simple, economical, and efficient solution for the maxillary frame process during denture restoration, meeting the oral rehabilitation needs of a wide range of patients, ensuring a smooth restoration process and maximizing treatment effectiveness.
[0041] like Figure 1 、 Figure 3 、 Figure 4As shown, further, the dental mold support part 120 of this embodiment specifically includes: a dental mold support platform 121 and a first mounting hole 122. The front of the dental mold support platform 121 is used to connect the model base 200. The first mounting hole 122 is opened on the dental mold support platform 121, which can be located in the middle position of the front of the dental mold support platform 121 and is set as a countersunk hole. The first magnetic component 130 is embedded in the first mounting hole 122, and the first magnetic component 130 can be fixed in the first mounting hole 122 by screws or adhesive fixation. In this way, the first magnetic component 130 can be stably installed on the dental mold support part 120, thereby achieving a stable magnetic connection effect.
[0042] like Figure 4 、 Figure 5 、 Figure 6 As shown, further, a positioning groove 123 is provided on the surface of the dental model support platform 121 of this embodiment, and the positioning groove 123 is located on the front side of the dental model support platform 121. A positioning platform 220 is protruding from the model base 200, and the positioning platform 220 is located on the back side of the model base 200. The positioning platform 220 is matched with the positioning groove 123 to enable the model base 200 to be limitedly connected to the transfer base 100. The inner contour of the positioning groove 123 matches the outer contour of the positioning platform 220, and the two are matched to fix their positions relatively. When the dental model 20 is connected to the transfer base 100 through the model base 200, the relative position of the dental model 20 and the transfer base 100 is fixed, and the orientation of the dental model 20 on the transfer base 100 does not change.
[0043] The positioning groove 123 of this embodiment can be an arc-shaped groove, and the corresponding positioning platform 220 can be an arc-shaped platform. For example, the cross-section of the positioning platform 220 is semicircular. In this way, when the model base 200 is magnetically connected to the transfer base 100, the arc-shaped positioning platform 220 can slide more smoothly into the arc-shaped groove, making the docking installation process more convenient.
[0044] like Figure 4 、 Figure 5 、 Figure 6 As shown, further, in this embodiment, a plurality of positioning grooves 123 are provided, and the plurality of positioning grooves 123 are arranged around the first mounting hole 122, and one end of the positioning groove 123 away from the first mounting hole 122 extends to the edge of the dental model support 121. A plurality of positioning platforms 220 are provided in a one-to-one correspondence with the plurality of positioning grooves 123, and each positioning platform 220 extends to the edge of the model base 200. The plurality of positioning grooves 123 are arranged around the first mounting hole 122, so that positioning can be achieved at multiple positions in the circumferential direction. When the multiple positions in the circumferential direction are matched and limited, the relative position of the model base 200 and the transfer base 100 is more stable, and is not easily displaced due to collision during the measurement process. This ensures the accuracy of the measurement during the maxillary frame process.
[0045] like Figure 3 、 Figure 4 、 Figure 5 As shown, further, a second mounting hole 210 is provided on the model base 200 of this embodiment, and a limiting step hole 211 is provided on the side of the second mounting hole 210 facing away from the transfer base 100, and the second magnetic member 230 is embedded in the limiting step hole 211. In the specific structure, the second mounting hole 210 passes through the model base 200, and the side of the second mounting hole 210 facing the front is a limiting step hole 211 (sinking structure), so that when the second magnetic member 230 is embedded in the second mounting hole 210, it is limited by the bottom surface of the limiting step hole 211, which facilitates the installation of the second magnetic member 230. A chamfer 212 is provided at the hole opening of the second mounting hole 210 on the side facing the transfer base 100, and the chamfer 212 is provided at the edge of the hole opening of the second mounting hole 210 facing the back. A blocking platform 124 is provided at the edge of the opening of the first mounting hole 122, and the blocking platform 124 is guided by the chamfer 212 to align the first mounting hole 122 with the second mounting hole 210; in the specific structure, the blocking platform 124 protrudes from the front of the dental mold support platform 121; when the model base 200 is magnetically connected to the transfer base 100, the protruding blocking platform 124 contacts the chamfer 212, and the model base 200 is moved by the guiding effect of the chamfer 212, and the center of the second mounting hole 210 is aligned with the center of the blocking platform 124, so that the model base 200 is aligned with the transfer base 100, which facilitates installation and improves measurement accuracy.
[0046] like Figure 4 、 Figure 5 As shown, further, the side surface of the dental mold support part 120 of this embodiment away from the mandibular frame connection part 110 is set as a docking surface 125, and the docking surface 125 is set horizontally or tilted at a predetermined angle. According to different usage requirements, the inclination angle of the docking surface 125 is different. In this embodiment, when the docking surface 125 is tilted at a predetermined angle, the predetermined angle is 3° or 5°. By setting the dental mold support part 120 with different inclinations such as 0°, 3°, and 5°, the transfer seat 100 adapted to the corresponding application scenario is matched according to the different inclinations of the condylar guide of the produced goods.
[0047] like Figure 4 、 Figure 5 、 Figure 6As shown, further, the jaw frame connecting part 110 of the embodiment specifically comprises a jaw frame connecting table 111, one side surface of the jaw frame connecting table 111 is provided with a dental model support part 120, the other side surface is provided with a limiting boss 112, and the limiting boss 112 is positioned on the jaw frame body 10. The limiting boss 112 is matched with the limiting structure on the jaw frame body 10, so that the jaw frame connecting table 111 is connected to the jaw frame body 10 and fixed in position by the limiting boss. Generally, the jaw frame body 10 is a standard part purchased, and the shape and position of the limiting structure are pre-set fixed, so only the limiting boss on the jaw frame connecting table 111 needs to be matched and designed.
[0048] In addition, the jaw frame connecting part 110 further comprises a third magnetic attraction part (not shown in the figure), which is arranged on the jaw frame connecting table 111 and is used for magnetically attracting and connecting the jaw frame body 10. The third magnetic attraction part can generate greater attraction force to more stably magnetically attract and connect the jaw frame body 10. It should be noted that the third magnetic attraction part can also not be additionally arranged, and the first magnetic attraction part 130 can also be magnetically attracted to the jaw frame body 10 by the attraction force to achieve magnetic attraction and connection.
[0049] As shown in Figure 1 , Figure 2 , Figure 3 As shown, further, the jaw frame connecting part 110 and the dental model support part 120 of the embodiment are integrally formed or detachably connected. In one way, the transfer seat 100 can adopt an integrated structure, which is integrally formed by plastic injection molding or 3D printing. The integrated structure has high structural strength, and when different height and angle use environments need to be dealt with, different height and angle transfer seats 100 can be pre-set to adapt to the needs of different patients and ensure good adaptability. The determination process of the height: based on a base jaw frame body, the overall height after the jaw frame is returned to zero is 70mm, the corresponding remaining space of the upper and lower jaws (after the preset height of the upper and lower seat bodies of the jaw frame body is removed) can be created by modeling, and the pre-product of the transfer seat 100 can be confirmed and made by opening a mold. Other remaining heights can be determined by digital editing to achieve standard parameterized production.
[0050] In another embodiment, the transfer seat 100 can be a detachable structure, and the jaw frame connection portion 110 and the dental model support portion 120 can be detachably connected by screws. The jaw frame connection portion 110 is set to a uniform standard, while the dental model support portion 120 can be set to different specifications according to different heights and angles of use. When it is necessary to cope with different heights and angles of use, only the dental model support portion 120 of the corresponding specifications can be replaced without replacing the jaw frame connection portion 110, thereby forming transfer seats 100 of different heights and angles, making the present dental model fixture more adjustable, optimizing the structure, and saving production costs.
[0051] Example 2
[0052] like Figure 1 、 Figure 2 、 Figure 3 As shown, this embodiment provides a jaw frame device, comprising a jaw frame body 10 and two dental model fixtures as described above. One dental model fixture is disposed on the upper portion of the jaw frame body 10 for connecting to an upper jaw model, and the other dental model fixture is disposed on the lower portion of the jaw frame body 10 for connecting to a lower jaw model.
[0053] In summary, the dental model fixture and jaw frame device proposed in this application reduces the number of components and the number and time required to apply plaster, making the operation process more streamlined, reducing waiting time for the working model, and saving time and effort. The structural design incorporates adjustable features, with pre-set height angles to adapt to the needs of different patients and ensure a good fit. By simplifying the material costs used in the manufacturing process, the new jaw frame magnetic transfer base is reusable, reducing the cost of purchasing accessories.
[0054] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
