Description

Technical Field

[0001] The present application relates to the technical field of denture production equipment, and more specifically, to a simple columnar jaw motion jaw frame. Background Art

[0002] The denture production process typically involves a maxillary frame process, where the upper and lower jaw models are mounted on the frame of the denture equipment. The patient's occlusion is determined, and the occlusal relationship between the upper and lower jaw models on the frame is adjusted to match the shape and position of the upper and lower teeth. In existing maxillary frame processes, depending on the degree of mandibular movement simulation, some require a simple frame to mount the upper and lower jaw models (dental models) on the frame and secure the models.

[0003] Existing traditional simple jaw frames are usually supported by multiple column structures, usually more than three, which can provide good stability and load-bearing capacity and are suitable for the production of various types of dentures. However, the end faces of the upper and lower column structures of the existing jaw frame are usually a convex spherical surface and a concave spherical surface embedded in each other. Due to the structure of the spherical surfaces connecting, they cannot move forward and backward, resulting in the upper and lower jaws being unable to move when they cooperate with each other, and the coordination is poor. When the upper and lower dental models perform jaw movements (such as opening and closing the jaw or lateral jaw movement), the upper and lower column structures will interfere with each other. For example, when the jaw is opened and closed, the column structure support will be stuck, resulting in the upper and lower dental models being restricted in jaw movement, which leads to inconvenience in use.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0038] In the process of traditional simple jaw frames using more than three columnar structural supports for support, not only will the upper and lower columnar structural supports interfere with each other when the upper and lower jaw models perform jaw movements, causing inconvenience in use. Moreover, since the columnar structural supports are added to the outside of the upper and lower jaw models, this design not only increases printing time and loss of printing materials, but also makes it easier to restrict the jaw movement of the upper and lower jaw models on the left and right outer sides, and they are easily stuck by the columnar structural supports during jaw opening movements. In addition, in some simple cases, the complex design of the jaw frame supported by more than three columnar structures has not shown its advantages, but has increased production costs and troubles. Therefore, this solution proposes the following embodiments to solve the above problems.

[0039] like Figure 1 、 Figure 2 、 Figure 3 As shown, this embodiment proposes a simple columnar jaw motion jaw frame, which is used in the upper jaw frame process of the upper jaw model 100 and the lower jaw model 300. The upper jaw model 100 and the lower jaw model 300 are fixedly connected to the upper and lower parts of the jaw frame body respectively, so that the upper jaw model 100 and the lower jaw model 300 can be checked and adjusted on the jaw frame body. Figure 1 、 Figure 2 As shown, for the convenience of structural description, the upper jaw model 100 is located above the lower jaw model 300 as a direction reference, and the components of this embodiment are structurally described based on this direction standard.

[0040] like Figure 2 、 Figure 3 、 Figure 5As shown, the simplified column-type jaw motion frame of this embodiment mainly includes: an upper maxillary support 200 and a lower mandibular support 400. The upper maxillary support 200 is used to connect to the upper jaw model 100 and is provided with an upper support column 210, which extends a predetermined length in the vertical direction; the lower mandibular support 400 is used to connect to the lower jaw model 300 and is provided with a lower support column 410, which extends a predetermined length in the vertical direction. In the specific structure, the maxillary support 200 can be the base part of the maxillary model 100. The maxillary model 100 usually has a tooth row 110, gums and a base at the bottom. Therefore, the base part of the maxillary model 100 can be directly used as the maxillary support 200; correspondingly, the base part of the mandibular model 300 can be directly used as the mandibular support 400; it should be noted that the maxillary support 200 can also be set separately, so that the maxillary support 200 is connected to the edge of the base of the maxillary model 100 and is protruding, so that the upper support column 210 can be set on the protruding maxillary support 200, and the technical effect can also be achieved. Similarly, the mandibular support 400 can also be set in the above manner. The end of the upper support column 210 facing away from the maxillary support 200 and the end of the lower support column 410 facing away from the mandibular support 400 are provided with a detachable docking structure 500; the detachable docking structure 500 includes a matching inclined convex surface 221 and an inclined concave surface 421, and the inclined convex surface 221 can slide along the inclined concave surface 421. In the specific structure, the lower end of the upper support column 210 and the upper end of the lower support column 410 cooperate to form the detachable docking structure 500, that is, the end surface of one of the upper support column 210 and the end surface of the lower support column 410 is provided with an inclined convex surface 221, and the end surface of the other is provided with an inclined concave surface 421. Therefore, during different movements of the jaw, the inclined convex surface 221 and the inclined concave surface 421 can slide and cooperate, thereby being able to adapt to the needs of different patients.

[0041] like Figure 2 、 Figure 4 、 Figure 6As shown, the simple column type jaw movement frame of this embodiment realizes support by cooperating the upper support column 210 of the maxillary support with the lower support column 410 on the mandibular support 400, so that the occlusal relationship of the upper jaw model 100 and the lower jaw model 300 can be determined and adjusted during the maxillary frame detection process. By providing a detachable docking structure 500 at one end of the upper support column 210 away from the maxillary support 200 and at one end of the lower support column 410 away from the mandibular support 400, and by designing that the inclined convex surface 221 can slide along the inclined concave surface 421, an adjustable function is achieved. When the upper and lower jaw models 300 are opened and closed or moved laterally during the restoration process, the sliding cooperation between the inclined convex surface 221 and the inclined concave surface 421 facilitates the end faces of the upper support column 210 and the lower support column 410 to slide apart, avoiding the problem of being stuck by the columnar structure support during the jaw opening movement. By providing a detachable docking structure 500 at the end face, the upper support column 210 and the lower support column 410 are facilitated to slide and dock and separate, which can solve the problem that the existing jaw frame cannot move the jaw, so that it can adapt to the needs of different patients, ensure good adaptability, and be more convenient to use.

[0042] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 As shown, further, the maxillary support 200, the upper support column 210 and the upper jaw model 100 of this embodiment are integrally formed, and the mandibular support 400, the lower support column 410 and the lower jaw model 300 are integrally formed. The entire jaw frame is divided into two parts, the upper and lower parts, each forming an integral structure, so that the simple column-type jaw movement jaw frame can be used for the production of partial dentures and full dentures in dental clinics, and is particularly suitable for printing oral scan model data with existing occlusal relationships. The use of an integrated production method can simplify the structure and process, and by simplifying the manufacturing process and the cost of materials used, it can reduce the patient's treatment costs and improve their acceptance. The simple column-type jaw movement jaw frame can provide a simple, economical and efficient solution for dental medical care, which is suitable for the oral restoration needs of a large number of patients.

[0043] like Figure 4 、 Figure 5 、 Figure 6As shown, the detachable docking structure 500 of this embodiment specifically includes a boss 220 and a groove 420. The boss 220 is provided at one end of the upper support column 210, and the side surface of the boss 220 is inclined to form an inclined convex surface 221. The groove 420 is provided at one end of the lower support column 410, and the side wall of the groove 420 is inclined to form an inclined concave surface 421. Therefore, the lower end of the upper support column 210 is protruded by the boss 220, and the upper end of the lower support column 410 is concave by the groove 420. The outer wall of the boss 220 is configured as a conical surface, and the inner wall of the groove 420 is configured to match. Thus, an adjustable function is achieved during the mating process of the upper support column 210 and the lower support column 410. The circular concave-convex structure with an inclined surface allows the upper and lower jaw models 100 and 300 to move open and close or lateral to the jaw during the restoration process, solving the problem of the existing built-in jaw frame being unable to move the jaws, making it adaptable to the needs of different patients and ensuring good adaptability.

[0044] like Figure 4 、 Figure 5 、 Figure 6 As shown, further, in this embodiment, the upper support column 210 has an upper support plane 211 formed on the end surface, located outside the boss 220, and the lower support column 410 has a lower support plane 411 formed on the end surface, located outside the groove 420. As a result, the outer diameter of the boss 220 is smaller than the outer diameter of the upper support column 210, and the inner diameter of the groove 420 is smaller than the outer diameter of the lower support column 410. These components form a relatively small, circular, detachable docking structure 500, facilitating jaw opening and closing or lateral jaw movement of the upper and lower jaw models 100 and 300 during occlusal adjustment. When the boss 220 is located within the groove 420, the lower support plane 411 supports the upper support plane 211, thus achieving stable support in the vertical direction via the upper and lower support columns 210 and 410.

[0045] like Figure 4 、 Figure 5 、 Figure 6 As shown, further, in this embodiment, a clearance groove 422 is provided on the bottom surface of the groove 420. The clearance groove 422 facilitates the processing of the groove 420, and when the boss 220 is inserted into the groove 420, it can provide a clearance position for the lower end surface of the boss 220, so that the outer side surface of the boss 220 and the inner side surface of the groove 420 can be stably matched.

[0046] like Figure 4 、 Figure 5 、 Figure 6As shown, the angles of inclination between the inclined convex surface 221 and the inclined concave surface 421 of this embodiment and the horizontal plane are both 10°-18°. Considering the design of the adjustable function to ensure more stable operation, the inclination angles of the inclined convex surface 221 and the inclined concave surface 421 of this embodiment are both 15° to accommodate the opening and closing or lateral jaw movement of the upper and lower jaw models during the restoration process.

[0047] like Figure 1 、 Figure 3 、 Figure 4 As shown, in this embodiment, the diameter of the upper support post 210 gradually decreases as it moves away from the maxillary support 200, while the diameter of the lower support post 410 gradually decreases as it moves away from the mandibular support. The upper support post 210 gradually decreases from top to bottom, making the thicker portion at the top more stable and structurally strong when connected to the maxillary support 200. The tapering portion at the bottom reduces space usage, provides a greater distance from the dentition 110 of the maxillary model 100, and prevents interference with the dentition 110. This also facilitates adjustment and determination of the occlusal relationship.

[0048] When designing a dental model, 1 to 3 pairs of upper support columns 210 and lower support columns 410 can be added as needed according to different usage scenarios. By designing a jaw frame with 1 to 3 pairs of support structures, the number of components is reduced, making the structure simpler.

[0049] like Figure 1 、 Figure 2 As shown, when applied to a unilateral model, only one pair of upper support columns 210 and lower support columns 410 are needed to fix the entire occlusal relationship; when applied to a model with missing anterior teeth 110, only one pair of upper support columns 210 and lower support columns 410 are needed to fix the entire occlusal relationship. When using a pair of upper support columns 210 and lower support columns 410, the upper support columns 210 are connected to the maxillary support 200 and are located on the inner side of the area surrounded by the teeth 110 of the upper jaw model 100. The lower support columns 410 are connected to the mandibular support and are located on the inner side of the area surrounded by the teeth 110 of the lower jaw model 300. In the specific structure, the teeth 110 on the model are arched, and the outline surrounded by the arch is the standard. A pair of upper support columns 210 and lower support columns 410 can be set in the middle position of the outline surrounded by the arch to achieve stable support.

[0050] like Figure 3As shown, when used in a unilateral or bilateral free-end model, one or two pairs of upper and lower support posts 210 and 410 are selected for support, depending on the need. When two pairs of upper and lower support posts 210 and 410 are provided for support, at least two upper support posts 210 are connected to the maxillary support 200 and positioned on the left and right sides outside the area enclosed by the dentition 110 of the upper jaw model 100; and at least two lower support posts 410 are connected to the mandibular support and positioned on the left and right sides outside the area enclosed by the dentition 110 of the mandibular model 300. By having two pairs of upper and lower support posts 210 and 410 supporting the left and right sides of the dentition 110, stable support is achieved.

[0051] When applied to an edentulous model, a maximum of three pairs of upper support columns 210 and lower support columns 410 are used for support. In this way, there is no need to wait for the upper jaw frame to be completed, and the occlusal relationship can be obtained after the model is printed. When there are three upper support columns 210 and three lower support columns 410. One of the upper support columns 210 is located on the inner side of the area surrounded by the teeth 110 of the upper jaw model 100, and the other two upper support columns 210 are located on the left and right sides outside the area surrounded by the teeth 110 of the upper jaw model 100; one of the lower support columns 410 is located on the inner side of the area surrounded by the teeth 110 of the lower jaw model 300, and the other two lower support columns 410 are located on the left and right sides outside the area surrounded by the teeth 110 of the lower jaw model 300.

[0052] In summary, the simple columnar jaw motion frame proposed in this application can be supported by one or two pairs of support structures, and a maximum of three pairs of support structures can be used, thereby reducing the number of components and making the structure simpler. The structural design takes into account the adjustable function and adopts a detachable docking structure to meet the needs of the upper and lower jaw models during the restoration process. This solves the problem that the original built-in jaw frame cannot move the jaw, making it able to adapt to the needs of different patients and ensuring good adaptability. By simplifying the material costs used in the manufacturing process, the patient's treatment costs are reduced, their acceptance is improved, and it is more economical and affordable.

[0053] 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.
