Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, specifically to a removable dental prosthesis model occlusal clamp. Background Technology

[0002] In the process of using removable denture models, an occlusal clamp is needed to work with the removable denture model to simulate the movement of the human upper and lower jaws and temporomandibular joint. However, the existing removable denture model occlusal clamp still has certain defects in the process of use.

[0003] As proposed in application number CN202120013055.1, a convenient occlusal appliance for denture fabrication includes a base. A connecting block three is fixedly connected to one side of the upper surface of the base. A support column is provided on the upper surface of the connecting block three. A slot two is formed on the support column. A movable block is provided inside the slot two. A locking device two is provided on one side of the movable block. When disassembling this convenient occlusal appliance for denture fabrication, by pulling the handle, the locking block moves out of the slot one under the action of a spring, thereby allowing the upper support plate to be removed. The locking device two also allows for the connection of electromagnets one and two. When the power is cut off, the push block and electromagnet one move out of the slot two under the action of spring two, thereby allowing the lower support plate to be removed. This structure facilitates quick disassembly of the device, making it easier for workers to process dentures and effectively improving the processing efficiency of dentures. However, in actual use, the denture model needs to be fixed on the upper and lower support plates with plaster, which reduces the ease of operation when disassembling the denture model. In addition, the positions of the upper and lower support plates in this application are relatively fixed, so it is impossible to make fine adjustments to the position of the denture model fixed on them, which reduces its practicality.

[0004] Therefore, we propose a removable denture model occlusal clamp to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a occlusal clamp for a removable denture model, so as to solve the problems mentioned in the background art of inconvenience in disassembling the denture model and inconvenience in fine-tuning the position of the denture model.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a removable denture model occlusal clamp, comprising a lower clamp assembly and an upper clamp assembly.

[0007] Connecting seats are fixedly installed on both sides of the rear end of the lower clamp assembly;

[0008] An adjustment mechanism is installed on the top of the upper clamp assembly, and a movable seat is sleeved on the adjustment mechanism;

[0009] A connecting rod rotatably passes through the bottom end of the movable seat and the top end of the connecting seat, and a positioning mechanism is installed at one end of the connecting rod.

[0010] Preferably, the lower clamping assembly includes a lower positioning plate fixedly installed between the connecting seats, a lower fixing column symmetrically installed on the top surface of the front end of the lower positioning plate, a lower positioning block fixedly installed on the top surface of the rear end of the lower positioning plate, a lower adjusting screw passing through the internal thread of the lower positioning block, and a lower clamping block rotatably connected to the front end of the lower adjusting screw.

[0011] Preferably, the upper clamping assembly includes an upper positioning plate movably connected to the bottom of the movable seat, upper fixing posts symmetrically installed at the bottom front end of the upper positioning plate, an upper positioning block fixedly installed at the bottom rear end of the upper positioning plate, an upper adjusting screw passing through the internal thread of the upper positioning block, and an upper clamping block rotatably connected to the front end of the upper adjusting screw.

[0012] The above-mentioned structural design facilitates the lower and upper clamping components to securely position the upper and lower parts of the removable denture model, preventing the removable denture model from shaking or falling off during occlusion simulation. At the same time, the lower and upper clamping components also facilitate the easy disassembly of the removable denture model, improving its practicality.

[0013] Preferably, the adjustment mechanism includes positioning shaft seats symmetrically installed on the top surface of the upper positioning plate, an adjustment rod is rotatably installed inside the positioning shaft seat, an adjustment knob is fixedly connected to the rear end of the adjustment rod, the adjustment rod is threaded through the center of the top of the movable seat, a slider is fixedly installed at the center of the bottom surface of the top of the movable seat, a limit groove is formed inside the upper positioning plate, and the slider is slidably connected to the limit groove.

[0014] The above-described structure allows for fine-tuning of the position of the upper clamping assembly via an adjustment mechanism, which in turn enables fine-tuning of the occlusal position between the upper and lower clamping assemblies. This facilitates adaptive adjustment based on the occlusal requirements of the removable denture model, thus improving its practicality.

[0015] Preferably, the positioning mechanism includes a fixed plate fixedly installed on the surface of the connecting rod, a spring connected to one side of the fixed plate, a movable plate connected to one end of the spring, a positioning rod fixedly installed on the top of the movable plate, and a positioning groove equally angled is formed on the inner side of the bottom of one end of the movable seat.

[0016] Preferably, the movable disc is slidably connected to the connecting rod, the movable disc is telescopically connected to the fixed plate via a spring, and the movable disc is engaged with the positioning groove via a positioning rod.

[0017] The above-mentioned structural design facilitates the rotation of the movable seat and connecting rod on the connecting seat, thereby facilitating the rotation of the upper clamping assembly relative to the lower clamping assembly. This is beneficial for driving the clamped movable denture model to perform occlusal simulation. The positioning mechanism facilitates the positioning of the rotation angle of the movable seat and the upper clamping assembly, which is beneficial for observing and adjusting the clamped movable denture model after positioning, thus improving the usability.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the removable denture model occlusal clamp;

[0019] 1. The lower clamping assembly and the upper clamping assembly can clamp and position the upper and lower parts of the removable denture model separately, and can ensure the stability of the removable denture model during the occlusal simulation process. At the same time, unlike the plaster fixation of the existing technology, it can quickly disassemble the removable denture model with the lower clamping assembly and the upper clamping assembly, which improves the convenience of disassembling the removable denture model. The adjustment mechanism can fine-tune the position of the upper clamping assembly at the bottom of the removable seat, which is beneficial for fine-tuning the occlusal position after the removable denture model is positioned and installed, thus improving its practicality.

[0020] 2. The movable seat and the connecting seat can be rotatably connected by the connecting rod, which makes it easy for the upper clamping assembly to rotate using the movable seat, and cooperate with the lower clamping assembly to realize the occlusal simulation of the removable denture model. The positioning mechanism can position the rotation angle of the movable seat and the upper clamping assembly, which is beneficial for observing and adjusting the clamped removable denture model during positioning, thus improving the usage effect.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a removable denture model occlusal clamp, including a lower clamp assembly 1 and an upper clamp assembly 3. Connecting seats 2 are fixedly installed on both sides of the rear end of the lower clamp assembly 1. The lower clamp assembly 1 includes a lower positioning plate 101 fixedly installed between the connecting seats 2. A lower fixing post 102 is symmetrically installed on the top surface of the front end of the lower positioning plate 101. A lower positioning block 103 is fixedly installed on the top surface of the rear end of the lower positioning plate 101. A lower adjusting screw 104 passes through the internal thread of the lower positioning block 103. A lower clamping block 105 is rotatably connected to the front end of the lower adjusting screw 104. The upper clamp assembly 3 includes an upper positioning plate 301 movably connected to the bottom of the removable seat 5. An upper fixing post 302 is symmetrically installed on the bottom front end of the upper positioning plate 301. An upper positioning block 303 is fixedly installed on the bottom rear end of the upper positioning plate 301. An upper adjusting screw 304 passes through the internal thread of the upper positioning block 303. An upper clamping block 305 is rotatably connected to the front end of the upper adjusting screw 304.

[0029] The design of the above structure allows the lower adjusting screw 104 to rotate and move within the lower positioning block 103 by rotating it. This allows it to rotate in conjunction with the lower clamping block 105 at the front end, moving the lower clamping block 105. Together with the symmetrically arranged lower fixing posts 102 at the front end, the lower plate of the removable denture model can be clamped and positioned. It also facilitates the disassembly of the lower half of the removable denture model when the lower clamping block 105 is retracted. Similarly, rotating the upper adjusting screw 304 allows it to move and position within the upper positioning block 303, facilitating the clamping and positioning of the upper half of the removable denture model in conjunction with the symmetrically arranged upper fixing posts 302 at the front end. The retraction of the upper positioning block 303 facilitates the disassembly of the upper half of the removable denture model, thus improving the ease of assembly and disassembly of the removable denture model using this occlusal clamp.

[0030] An adjustment mechanism 4 is installed on the top of the upper clamping assembly 3. A movable seat 5 is sleeved on the adjustment mechanism 4. The adjustment mechanism 4 includes a positioning shaft seat 401 symmetrically installed on the top surface of the upper positioning plate 301. An adjustment rod 402 is rotatably installed inside the positioning shaft seat 401. An adjustment knob 403 is fixedly connected to the rear end of the adjustment rod 402. The adjustment rod 402 is threadedly connected to the top center of the movable seat 5. A slider 404 is fixedly installed at the center of the top bottom surface of the movable seat 5. A limit groove 405 is opened inside the upper positioning plate 301. The slider 404 is slidably connected to the limit groove 405.

[0031] The design of the above structure allows the adjustment lever 402 to rotate inside the positioning shaft seat 401 by rotating the adjustment knob 403. During the rotation, the adjustment lever 402 can use the threaded connection with the slider 404 to drive the upper clamping assembly 3 to make fine adjustments to its position. This is beneficial for fine-tuning the relative position between the upper clamping assembly 3 and the lower clamping assembly 1, and for fine-tuning the relative position of the upper and lower parts of the removable denture model according to the occlusal model of the removable denture model.

[0032] A connecting rod 6 is rotatably passed through the bottom end of the movable seat 5 and the top end of the connecting seat 2. A positioning mechanism 7 is installed at one end of the connecting rod 6. The positioning mechanism 7 includes a fixed plate 701 fixedly installed on the surface of the connecting rod 6. A spring 702 is connected to one side of the fixed plate 701. A movable disc 703 is connected to one end of the spring 702. The movable disc 703 is slidably connected to the connecting rod 6. The movable disc 703 is telescopically connected to the fixed plate 701 through the spring 702. A positioning rod 704 is fixedly installed on the top of the movable disc 703. A positioning groove 705 is opened at an equal angle on the inner side of the bottom of one end of the movable seat 5. The movable disc 703 is engaged with the positioning groove 705 through the positioning rod 704.

[0033] The design of the above structure allows the positioning rod 704 to disengage from the positioning groove 705 by pulling the movable plate 703. At this time, the upper clamping assembly 3 and the movable seat 5 can rotate on the connecting seat 2 using the connecting rod 6. During rotation, the upper part of the movable denture model being clamped will engage with the lower part of the movable denture model being clamped on the lower clamping assembly 1 to simulate biting. When it is necessary to observe and adjust the movable denture model in detail, the movable plate 703 is reset by using the spring 702, which will cause the positioning rod 704 to engage with the positioning groove 705. This allows the upper clamping assembly 3 and the clamped movable denture model to be positioned at different angles, which is beneficial for stable observation and adjustment of the movable denture model after positioning.

[0034] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
