Detailed Implementation

[0021] The present invention will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0022] like Figures 1 to 3 As shown, a 3D-printed dental quick-release digital occlusal articulator includes an upper occlusal portion 100 and a lower occlusal portion 200. One end of the upper occlusal portion 100 and the lower occlusal portion 200 are hinged by a pin 300. The free ends of the upper occlusal portion 100 and the lower occlusal portion 200 are respectively provided with corresponding upper and lower locking devices 400. The upper and lower locking devices 400 are used to fix the maxillary model and the mandibular model, respectively. The locking device 400 includes a mounting block 410. A model fixing space 420 is provided on the outer side of the mounting block 410. A model limiting mechanism 430 is provided on one side of the model fixing space 420. One end of the maxillary model or the mandibular model is placed in the model fixing space 420 and fixed by the model limiting mechanism 430. The opening and closing process of the upper occlusal portion 100 and the lower occlusal portion 200 is controlled to drive the maxillary model and the mandibular model to simulate the occlusal relationship.

[0023] The model limiting mechanism 430 includes a rotating pin 431. The free end 432 of the rotating pin 431 is retractable and extendable into the model fixing space 420 to limit and release the model. The rotating pin 431 includes a pin body 432, which is connected to the mounting block 410 via a tension spring. A limiting strip 433 and a limiting slot 434 are correspondingly provided between the pin body 432 and the mounting block 410 to restrict the free end 432 from entering and exiting the model fixing space 420. When the pin body 432 is rotated, and the limiting strip 433 enters the limiting slot 434, the free end 432 simultaneously enters the model fixing space 420 to clamp and limit the model. When the limiting strip 433 is pulled out of the limiting slot 434, the pin body 432 is rotated again until the limiting strip 433 is locked outside the limiting slot 434, at which point the limitation on the model is released. Figure 4 , Figure 5 The image shows the 431 rotary pin quick-release structure. This structure has two states: locked and unlocked. The model is secured by rotating the rotary pin and inserting the free end into the corresponding small hole on the model. The rotary pin has a built-in spring for quick and easy opening and locking.

[0024] The model positioning groove 421 is arranged in the model fixing space 420, which can make the fixed end of the model more accurately placed in the model fixing space 420, and ensure that the free end 432 quickly connects with the fixed end of the model.

[0025] With the cooperation of the rotating bolt 431 and the model positioning groove 421, the digital model can be quickly disassembled without the aid of other tools, and the positioning is accurate and will not cause wear to the digital model, thereby ensuring the accuracy of the digital model bite relationship.

[0026] The clamping device 400 is detachably connected with each corresponding bite part (the upper bite part 100 or the lower bite part 200), the mounting block 410 is connected with the bite part through a spring tensioning connection, the spring can tightly connect the mounting block 410 with the bite part, and meanwhile, the spring has toughness, so that the mounting block 410 and the bite part can longitudinally move, thereby the upper jaw model and the lower jaw model can simulate a multi-orientation bite process, the mounting block 410 and the bite part are respectively provided with through holes 440, and the two ends of the spring are fixed in the two through holes 440, and the spring is detachably arranged.

[0027] The mounting block 410 and the bite part are correspondingly provided with a positioning mechanism, the positioning mechanism comprises a limiting bead 450 arranged on the bite part 410 and a limiting groove 460 arranged on the mounting block 410 and capable of accommodating the limiting bead 450, the limiting bead 450 and the limiting groove 460 are arranged for quickly and accurately connecting the mounting block 410 with the bite part, that is, the front end and the rear end of the bite frame are connected through two limiting beads 450 and a spring. The spring keeps the front end and the rear end closely connected while allowing the front end and the rear end to move. The limiting bead 450 provides an accurate fixed position, so that the front end can be reset to the correct position after each movement.

[0028] The upper bite part 100 and the lower bite part 200 are provided with a movable pad 500 for limiting the angle between the upper bite part 100 and the lower bite part 200, one end of the movable pad 500 is connected with the upper bite part 100 and the lower bite part 200 through a pin rod 700, and the other end can be adjusted up and down between the upper bite part 100 and the lower bite part 200, when the movable pad 500 is horizontally placed, the upper bite part 100 and the lower bite part 200 can be kept parallel when closed. When the movable pad 500 is inserted into the upper jaw frame, the upper bite part 100 and the lower bite part 200 can be kept at a fixed angle when closed, and the angle can be adjusted according to actual needs.

[0029] Two positioning mechanisms are arranged between the mounting block 410 and the bite part, and the spring is located at the midpoint of the connecting line of the two positioning mechanisms, thereby further ensuring the accuracy of the relative position when the mounting block 410 is connected with the bite part.

[0030] Both ends of the spring are fixed into the through hole 440 through the bolt 600.

[0031] In conclusion, the 3D printing dental quick-release digital articulator based on the present application can effectively solve the problem of inaccurate digital model bite relationship caused by the fixed position deviation of the model after multiple installation and disassembly by setting the detachable clamping device at the free end of the upper and lower occlusal parts. It does not require other tools, realizes quick installation and disassembly of the digital model, and due to the convenience of disassembly, only one articulator is needed for each worker, greatly reducing the production cost and improving the efficiency.
